============================
  MAJOR FEATURES & CHANGES
============================

Change 3658809 by Chris.Bunner

	Changing default HDR display gamut to P3 as in practice that's more common than Rec2020, this should be a user-facing option where possible though as we can't automatically retrieve that data.

Change 3658842 by Chris.Bunner

	Backing out previous HDR default gamut change as it conflicts with mandatory platform defaults.

Change 3695269 by Arne.Schober

	DR - Make clang happy wreorder

Change 3695418 by Guillaume.Abadie

	Fixes compilation failure in FoliageType_InstancedStaticMesh.cpp.

Change 3695430 by Guillaume.Abadie

	DR - vk - Custom memory allocator
	Remove old/unused stats

Change 3697486 by Rolando.Caloca

	DR - vk - Fix validation issue

Change 3697488 by Richard.Wallis

	Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6.  Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.

	Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.

	#jira UE-37553

Change 3697501 by Richard.Wallis

	Move audio processing over to audio bus tap.  Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework.  This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.

	Original Code Review Description:

	Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer.  This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac.  There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.

	- Stuttering Audio Performace issue investiagation:  Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one.  Basic investigation seems to point to somewhere in the engine audio handing.  When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue.  I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough.  This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

	#jira UEPLAT-1677

Change 3697517 by Richard.Wallis

	XCode 9.0 extra nullability specifiers required.

Change 3697537 by Richard.Wallis

	Back out revision 23 from //UE4/Dev-Rendering/Engine/Plugins/Media/AvfMedia/Source/AvfMedia/Private/Player/AvfMediaTracks.cpp

Change 3697670 by Rolando.Caloca

	DR - vk - Fix mapstaging surface

Change 3697846 by Uriel.Doyon

	Allow denormalized values when converting float32 to float16.

Change 3697892 by Uriel.Doyon

	Fix for unaligned structure elements

Change 3699335 by Richard.Wallis

	Mac compile fix - turns out I did need these nullability specifiers here.

Change 3699663 by Guillaume.Abadie

	Fixes time unit conversions from microseconds to milliseconds error in dynamic resolution heuristic when using GPU busy time queries.

Change 3699959 by Rolando.Caloca

	DR - Fix barrier in the middle of render pass

Change 3699969 by Rolando.Caloca

	DR - vk - Change dump layer location so it prints out validation ids

Change 3700356 by Guillaume.Abadie

	Implements secondary screen percentage to be able to do TAA upsample followed spatial upscale so that the editor viewport still have same TAA upsample screen percentage range to test the content with no matter monitor's DPI.

Change 3701105 by Guillaume.Abadie

	Ignore per view automatic mip bias on texture type other than 2d textures.

	#jira UE-51396

Change 3702297 by Richard.Wallis

	Mac compile fix for nullable specifier.  Looks like Obj class using the C++ class also needs this otherwise it throws.  Seems to be some kind of xcode/compiler caching bug with this stuff as it'll report the error once then on subsequent compiles say everything is ok.

	#jira UE-51386

Change 3702357 by Richard.Wallis

	Mac nullability compile fix - again.  Looks like I fell foul of that xcode compile caching!
	#jira UE-51386

Change 3702424 by Guillaume.Abadie

	Fixes planar reflection from drowing themselves in their own FSceneRenderer in forward shading.

	#jira UE-51395

Change 3702464 by Guillaume.Abadie

	Fixes wrong viewport to buffer conversion of the distortion.

	#jira UE-51406

Change 3702819 by Guillaume.Abadie

	Fixes planar reflections with secondary screen percentage for HighDPI editor viewports.

Change 3703732 by Guillaume.Abadie

	Removes unecessary check(); when there is more than 2 players with planar reflections.

	#jira UE-51436

Change 3704302 by Guillaume.Abadie

	Removes unecessary Interface suffix on new dynamic resolution related interfaces

Change 3704390 by Chris.Bunner

	Fixed a coincidentally correct define.

Change 3704730 by Rolando.Caloca

	DR - vk - Fix map for depth surfaces

Change 3704739 by Rolando.Caloca

	DR - Debug label on D3D11 UAVs
	- Validate when running -d3debug

Change 3705000 by Chris.Bunner

	Skip compiling opacity and opacity mask inputs on opaque surface materials. Previously the code was always added to the shader, sometimes we force opaque materials down a masked path which then calls the dormant code unintentionally. A safer fix for UE-48254.
	Partially reverted previous fix in CL 3608303 which removed a material instance optimization caching the overridden base properties.

Change 3706065 by Guillaume.Abadie

	Does some renaming for primary screen percentage, and move the primary screen percentage method selection from dynamic resolution driver to FSceneView.

Change 3706464 by Chris.Bunner

	Fixed material property translate overrides that were generating code in the wrong entry.
	Fixed conditions  in If material expression GetInputType and IsMA check.

	#jira UE-51368

Change 3706641 by Chris.Bunner

	Missing "break" in switch statement (which unfortunately needs another bump to resolve).

Change 3706642 by Guillaume.Abadie

	Fixes assertion failure when r.TemporalAA.EnableUpscale = 1

Change 3706650 by Gil.Gribb

	UE4 - UE4 - Changes from intel. Increase number of worker threads on Windows to if hyperthreads (hyperthreads √ 2) else cores √ 1 up to a max of 22 workers. Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3706733 by Daniel.Wright

	Print Embree Build time

Change 3706841 by Daniel.Wright

	EmbreeFilterFunc4 now handles masked out intersections properly

Change 3707437 by Rolando.Caloca

	DR - vk - Android compile fix

	#jira UE-51474

Change 3707785 by Guillaume.Abadie

	Fixes viewport issue in bloom setup pass with TAA upsample.

Change 3709623 by Rolando.Caloca

	DR - vk - Missing barrier for reading into cpu

Change 3709633 by Rolando.Caloca

	DR - vk - Compile fix

Change 3710454 by Mark.Satterthwaite

	Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
	- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
	- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
	- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
	- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
	- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
	- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
	- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
	- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.

Change 3710456 by Mark.Satterthwaite

	Fix the Eddie workset project generator so that Enterprise projects don't get mixed in with regular projects at the top-level because of the way Eddie combines workset groups.

Change 3710457 by Mark.Satterthwaite

	DX11 texture formats for Mac Metal please!

Change 3710480 by Mark.Satterthwaite

	Permit RHI thread and parallel execution in Mac -game mode again.

Change 3710522 by Mark.Satterthwaite

	MSVC type-mismatch error fixes.

Change 3710580 by Mark.Satterthwaite

	Alright then - if I can't use the C++11 extended string semantics I'll have to use "xxd -i" to generate a hex-dump include header from ue4_stdlib.metal instead. This can only be updated from a machine with access to the POSIX xxd command (Mac & Linux, possibly the new Linux sub-system for Win10).

Change 3710616 by Mark.Satterthwaite

	Missing file.

Change 3712972 by Guillaume.Abadie

	Fixes Circle DOF's negative alpha channel getting clamped to 0 in TAA pass.

Change 3712979 by Guillaume.Abadie

	Fixes wrong RT reallocation when doing TAA upsample in editor viewports with secondary upscale.

Change 3713406 by Mark.Satterthwaite

	Use GPU morph targets on Mac - the necessary buffer conversions will always be available there. For iOS it can only be supported if iOS 10 is the minimum OS & Metal standard so leave that on the CPU path for now.

Change 3713494 by Richard.Wallis

	Fix for hitch when PIE unloading sublevel.  PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads.  However they all just need to read the data not change it.  Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.

	Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.

	Also tested again repro in linked bug UE-24711.

	#jira UE-40533

Change 3713612 by Mark.Satterthwaite

	Integrate LPV_STORE_INDEX_IN_HEAD_BUFFER related changes from //depot/Partners/Microsoft/UE4-MS/Engine-Fable @ 2954744

	This should make Light Propagation Volumes potentially viable on non-Microsoft platforms.

Change 3713623 by Mark.Satterthwaite

	Implement ByteAddressBuffer/RWByteAddressBuffer in hlslcc in a similar manner to StructuredBuffer/RWStructuredBuffer so that the backends don't need too much modification. Implement the necessary changes into MetalBackend to make this work for Metal.

	Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.

Change 3713636 by Mark.Satterthwaite

	Enable LPVs for Mac Metal.
	- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
	- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
	- Turn on LPVs for Metal as it works now.

Change 3714049 by Guillaume.Abadie

	Do not set screen percentage method to TAA upsample when anti aliasing method is not TAA even if there is automatic fallback in the renderer.

Change 3714306 by Guillaume.Abadie

	Fixes assertion failure in dynamic resolution state proxy with GPU busy time queries.

Change 3714714 by Mark.Satterthwaite

	Tweak Metal GPU identification so that it works with eGPU boxes and protoype hardware - these changes only apply to macOS 10.13 so the system as a whole remains.

Change 3716104 by Mark.Satterthwaite

	Fix 10.12/Xcode 8 compile errors from the build-farm which is still split until Fortnite can update.

Change 3716120 by Mark.Satterthwaite

	Silence static-analysis.

Change 3716158 by Guillaume.Abadie

	Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3716271 by Daniel.Wright

	Lightmass correctness fixes
	* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
	* Photon density trimming intended for direct photons was affecting indirect photons as well.  This caused high noise for point / spot lights with a large attenuation radius.  Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
	* Removed legacy fudge factor on point / spot light photon energy
	* Spotlights no longer emit based on indirect photon paths.  Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
	* Fixed photons computing one more bounce than requested.
	* Added an option to use the Radiosity solver for all multibounce, replacing photons.  Useful as a reference but generally too much noise indoors.
	* Fixed visualization of photons without final gather

Change 3716434 by Mark.Satterthwaite

	Backout the remaining change from 3632041 that is no longer necessary - this was the last of the 4.18 Metal workarounds.

Change 3716491 by Chris.Bunner

	Fixing up an edge-case on a recent optimization.

Change 3716611 by Guillaume.Abadie

	Allows secondary screen percentage >= 100%.

Change 3716977 by Guillaume.Abadie

	Back out changelist 3716158 to unblock QA pass.

	#jira UE-51580

Change 3717111 by Arne.Schober

	Fixing nomalization of Morph Tangents https://udn.unrealengine.com/questions/392462/
	Also implemanted batching of the dispatches which should help worst case perfomance where dispatches become too small.
	CalculateInverseAccumulatedWeights is not cheap and proably should be moved onto a task thread that runs as soon as the input weights are ready.

Change 3717127 by Mark.Satterthwaite

	Fix a mismerge from the reversion of 3632041 - part of the modified code had been moved into another file and I didn't initially notice.

Change 3717178 by Mark.Satterthwaite

	Remove useless copy-pasted expressions from glsl_type::GetByteAddressBufferInstance & force MetalBackend to relink. Apparently the previous Mac libs were mysteriously broken.

	#jira UE-51583

Change 3717476 by Marcus.Wassmer

	Fix PS4 compile.  funciton local statics not allowed on PSSL
	Also enabled the new atomics method for LPVs for all platforms

Change 3717502 by Arne.Schober

	DR - Compiletime option for compressed ruleset (0.02ms perf gain on PS4 and disabled by default as it limits array size to 2million entries)

Change 3717601 by Arne.Schober

	DR - Move cycle counter into more meaningfull locations.

Change 3718054 by Guillaume.Abadie

	Removes unecessary check() failure on secondary upscale that fires when testing raw output screen percentage method.

Change 3718066 by Guillaume.Abadie

	Reland: Rewrites editor primitive compositing to support TAA upsample.

	This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.

Change 3718589 by Mark.Satterthwaite

	Console-variable to enable and disable Manual-Vertex-Fetch for Metal and fix the internal code to handle the subtle changes in behaviour for vertex-declarations so we don't explode under the Metal validation layer. MVF works on macOS, though testing did expose an error with Tessellation on Nvidia (true for MVF enabled & disabled).

Change 3718633 by Guillaume.Abadie

	Fixes temporal instability issue of TAA upsample with secondary screen percentage.

Change 3718658 by Arne.Schober

	DR - 25% MorphTarget Speed increase because there was a bit of cache thrashing between the waves going on.

Change 3718818 by Mark.Satterthwaite

	Fix compilation on hlslcc - integral values are not automatically converted into comparisons with zero.

Change 3719004 by Guillaume.Abadie

	Lets the game viewport client automatically set raw output screen percentage method when doing dynamic resolution with stereo rendering but without TAA upsample.

Change 3719375 by Mark.Satterthwaite

	Extend mtlpp compiler testing app to support Metal tessellation compute shaders so we can send Nvidia a much simpler reproduction of their regression.

Change 3720099 by Mark.Satterthwaite

	Make the left-hand arguments work in airdiff.

Change 3720413 by Mark.Satterthwaite

	Support standalone compute shaders in the mtlpp compiler test app.

Change 3721232 by Mark.Satterthwaite

	No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

Change 3721244 by Mark.Satterthwaite

	Fix incorrect enum handling for Metal features due to overflow.

	#jira UE-51643

Change 3721338 by Mark.Satterthwaite

	MIssing file from 3721232

Change 3722139 by Arne.Schober

	DR - [UE-51602] -Fixed Typo that accidently bound the LightingInstancebuffer to the Transform one

	#jira UE-51602

Change 3722165 by Rolando.Caloca

	DR - Default -opengl to GL4

Change 3722682 by Guillaume.Abadie

	Fixes wrong clear color in SSR important for VR that has a HMD mesh.

Change 3722766 by Rolando.Caloca

	DR - Fix static analysis

Change 3722943 by Mark.Satterthwaite

	Disable the METAL_SM5_NOTESS shader platform again - I can workaround the Nvidia pipeline state compiler crash by changing the buffer address space from "constant" to "device" as we're managing to confuse the poor thing. This won't materially affect AMD or Intel as they don't care much about this, but to limit performance issues on Nvidia we only need to do this for Tessellation Compute shaders.

Change 3723100 by Mark.Satterthwaite

	Apparently users like enabling Metal shader standards that won't work on their current OS, so don't display those that aren't going to work & display an error message before quitting rather than crashing when trying to load a project that tries to use an incompatible shader version.

	Render thread dynamic resolution & TAA upsample.

	Merging //Tasks/UE4/Dev-DynamicRes/...@3694528 to //UE4/Dev-Rendering/...

	New features breakdown:
	- TAA upsample compute shader that accepts screen percentage from 50% to 200%, with a faster shader permutation for consoles;
	- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
	- Material texture per view mip bias to produce sharper images with TAA upsample;
	- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
	- Dynamic resolution in PIE and game builds;
	- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can  exactly associate GPU frame times with screen percentages in its history;
	- Game user settings to enable/disable dynamic resolution;
	- In editor viewport screen percentage config to previsualise and test content at different screen percentage.

	Fixes:
	- Various fixes for algorithms producing different outputs at different screen percentage.
	- Various fixes for algorithms sampling outside view rects.

	Refactors:
	- TAA shader
	- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.

	Aknowledgements:
	- VR plugins are broken
	- DFAO still have some artifacts

	Premiliminary review: Marcus.Wassmer
	Review for TAA refactor and TAA upsample shader: Brian.Karis
	Review for dynamic resolution: Brian.Karis

MAJOR FEATURES + CHANGES
==========================

Change 3209340 on 2016/11/23 by Ben.Marsh

	Convert UE4 codebase to an "include what you use" model - where every header just includes the dependencies it needs, rather than every source file including large monolithic headers like Engine.h and UnrealEd.h.

	Measured full rebuild times around 2x faster using XGE on Windows, and improvements of 25% or more for incremental builds and full rebuilds on most other platforms.

	  * Every header now includes everything it needs to compile.
	        * There's a CoreMinimal.h header that gets you a set of ubiquitous types from Core (eg. FString, FName, TArray, FVector, etc...). Most headers now include this first.
	        * There's a CoreTypes.h header that sets up primitive UE4 types and build macros (int32, PLATFORM_WIN64, etc...). All headers in Core include this first, as does CoreMinimal.h.
	  * Every .cpp file includes its matching .h file first.
	        * This helps validate that each header is including everything it needs to compile.
	  * No engine code includes a monolithic header such as Engine.h or UnrealEd.h any more.
	        * You will get a warning if you try to include one of these from the engine. They still exist for compatibility with game projects and do not produce warnings when included there.
	        * There have only been minor changes to our internal games down to accommodate these changes. The intent is for this to be as seamless as possible.
	  * No engine code explicitly includes a precompiled header any more.
	        * We still use PCHs, but they're force-included on the compiler command line by UnrealBuildTool instead. This lets us tune what they contain without breaking any existing include dependencies.
	        * PCHs are generated by a tool to get a statistical amount of coverage for the source files using it, and I've seeded the new shared PCHs to contain any header included by > 15% of source files.

	Tool used to generate this transform is at Engine\Source\Programs\IncludeTool.

Change 3122543 on 2016/09/13 by Ben.Woodhouse

	Override HasOcclusion for Widget3DComponentProxy to detect if the material is has depth testing enabled.

	#jira UE-35878

Change 3122544 on 2016/09/13 by Ben.Woodhouse

	Shadow stencil optimisation with cvar (enabled by default)

	Avoids redundant clearing the stencil buffer for per-object and pre shadows by zeroing the stencil during testing, following discussion on UDN.

	This means we don't benefit from Hi Stencil on GCN for the shadow projection draw calls, but it's still faster in all the cases I could find, including for the player character where the bounding box is quite large. (Note: early stencil still works fine, according to PIX)

	Shadow projection GPU time profiling :
	Test map with 35 characters, stationary directional light
	  - 4ms-2ms on XB1
	  - 2.5ms to 0.9ms on PC (r9-390X)
	  - 3ms-2ms on PS4

	Paragon PS4 (roughly 20% reduced - from ~0.39ms)

	DR - [UE-34481] - Extract all the State which is necessary to execute the DebugTextDrawingDelegate from the SceneProxy into its own Helpers to be drawn to the canvas later on.

Change 3127130 on 2016/09/15 by Mark.Satterthwaite

	Add overloads to as* functions in hlslcc - HLSL allows you to call these on variables of the same type, in which case it simply returns the existing value but we had only defined the float<->u/int conversions, so hlslcc added implicit casts that broke such cases (i.e. asuint(uint) -> floatBitsToUint(float(uint))). This change defines the missing overloads as returns with regular casts.

	Improve vector noise tooltips & documentation

Change 3130547 on 2016/09/19 by Ben.Woodhouse

	Fix for ensure fail when initializing point light shadowmaps.

	This came about because cubemap rendertargets always have Extents of (Resolution, 0). The Y component was implicitly used to determine if it was a cubemap, which is odd... The fix was to make the definition explicit via a flag and initialize both the X and Y parameters.

	I suspect the ensure started happening recently due to a more recent change, but fixing the underlying logic seems like the correct fix.

	- Disable framebuffer recycling as its causing a hang

Change 3131625 on 2016/09/19 by Mark.Satterthwaite

	Inside MetalRHI add an optional cache for disposed texture objects so we may reuse them - controlled by CVAR rhi.Metal.TextureCacheMode which must be set prior to running as it can't be changed at runtime. Settings: 0 = off, 1 (default) = will attempt to reuse private memory texture objects within the frame they are released otherwise they are disposed of as before. Setting 2 extends the caching to all textures - though Managed/Shared textures cannot be reused until after the frame in which they were released has been processed on the GPU. In this mode id<MTLTexture> objects are never returned to the OS so in order to conserve VRAM calls to setPurgeableState are made to allow the driver to reclaim unusued memory if required.

This needs to be rethought to pack these into fewer command buffers with the same synchronisation requirements to minimise command-buffer splits but for now we'll just make the default sufficiently large that we shouldn't see the hang until the work is done. Also ensure that command-buffer failure is always fatal - there is no way to recover or continue if a command-buffer fails.

Change 3140360 on 2016/09/26 by Daniel.Wright

	Lighting Scenarios and lightmaps moved to separate package
	* Levels can be marked as lighting scenarios (eg Day, Night).  Lighting is built separately for each lighting scenario with actors / lights in all other scenario levels hidden.  Only one lighting scenario level should be visible at a time in game, and its lightmaps will be applied to the world.
	* Most outputs of the lighting build now go into a separate _BuiltData package.  This improves level Save and AutoSave times as the separate package will only be dirtied after lighting rebuilds.
	* If a lighting scenario is present, all lightmaps are placed inside it's _BuiltData package.  This means that only the currently loaded lighting scenario's lightmaps will be loaded (Day or Night, but not both).  This also means that lightmaps for a streaming level will not be streamed with it.
	* For backwards compatibility, existing lightmaps are moved to a new _BuiltData package on load.
	* Reflection captures and precomputed visibility were not moved to the separate package.  Reflection captures are force updated on load of a lighting scenario level, which can increase load times.

Renamed the heavy weight members on this struct to Compute*. Methods that modify The ViewMatrices have been renamed to Hack* to discurage their use in the future until a better solution for those problems is found. The ViewMatrix modification is especially misleading because it only changes the State of the ViewMatrices to read their Position from the Material Editior as if coming from the Lightsource (mainly for manual bilboards) as well as doing someting similar to generate CPU bilboards for shadows.

==========================
MAJOR FEATURES + CHANGES
==========================

Change 2973846 on 2016/05/11 by Jamie.Dale

	Exposed FConfigValue::ExpandValue and added FConfigValue::CollapseValue

	These are both static and can be used to expand or collapse the macros used in our config files (mostly when dealing with paths), in code that has to deal with the config system, but isn't internal to the config system (mostly things that deal with default configs outside of UObjects).

	The old non-static version of FConfigValue::ExpandValue is now FConfigValue::ExpandValueInternal, which just calls FConfigValue::ExpandValue on SavedValue and ExpandedValue.

	This also changes some code that was using FString.Replace to use FString.ReplaceInline. This reduces allocations, and also allows us to avoid another string comparison to see whether the strings are identical (as ReplaceInline returns the number of replacements that were made).

Change 2973847 on 2016/05/11 by Jamie.Dale

	Changing the loading phase in the localization dashboard now writes to the default config

	#jira UE-30482

Change 2973866 on 2016/05/11 by Jamie.Dale

	Deprecated some functions that were taking an unused position.

	These unused parameters caused confusion and lead to UE-30276. The old versions have been deprecated, and new versions without those parameters have been added. Existing code has been updated to call the non-deprecated version.

	- FViewportFrame::ResizeFrame
	- FSceneViewport::ResizeFrame
	- FSceneViewport::ResizeViewport

Change 2974505 on 2016/05/11 by Nick.Darnell

	PR #2309: Added Combobox styling (Contributed by Chris528)

Change 2975241 on 2016/05/12 by Richard.TalbotWatkin

	Made sRGB Preview the default in the Color Picker.

Change 2975390 on 2016/05/12 by Jamie.Dale

	Made sure that en-US-POSIX is in our list of available cultures

	Some people use machine tags as their native text, so they need an invariant machine like culture to use as their native culture. en-US-POSIX is perfect for this.

Change 2975411 on 2016/05/12 by Jamie.Dale

	PR #2237: Fixed formatting of Error_TooManyMaterials message (Contributed by pfranz)

Change 2975559 on 2016/05/12 by Jamie.Dale

	Dialogue Wave VO direction can now be localized

	This is gathered as editor-only data.

	Resolved some loc key conflicts

	#jira UE-25833

Change 2975774 on 2016/05/12 by Jamie.Dale

	PO files now only contain a single entry in the case of a native translation being exported

	They used to contain the original entry, as well as an entry for the native translation, however the original entry would never be used.

	This change also cleans up some directory walking code that was looking for archive files, and replaces it with code to load the specific archive file.

Change 2975776 on 2016/05/12 by Jamie.Dale

	Downgraded a PO file import warning that isn't really an issue

	#jira UE-25833

Change 2976675 on 2016/05/13 by Jamie.Dale

	Fixed some more fallout from changes to use the window position when changing the game viewport mode

	- FSceneViewport::ResizeFrame:
	  - Fixed the HMD monitor info setting the wrong variables.
	  - Fixed SetWindowMode and ResizeViewport potentially being passed two different modes.
	  - We now only move the window if we need to (this avoids issues with WindowedFullscreen window positioning).

	- FWindowsWindow::MoveWindowTo:
	  - Now treats the screen space position it's given as relative to the top-left of the window, rather than the top-left of the windows' client area.

	- FWindowsApplication:
	  - WM_MOVE was passing a screen space position relative to the top-left of the windows' client area, rather than its window area like Slate expected.

	#jira UE-30276
	#jira UE-30677

Change 2976804 on 2016/05/13 by Jamie.Dale

	Slight optimization to FICUInternationalization::FindOrMakeCulture to avoid hitting the filesystem until we know we need to

	The FBX Importer no longer runs cleanup upon failing to import an FBX file and won't crash the engine the next time an FBX is imported within the same editor session.

	Fbx tests automation
	#jira UE-29635

Change 2978797 on 2016/05/16 by Alexis.Matte

	#jira UE-30774
	- prevent baking the pivot if we transform the vertex with the absolute transform.
	- Also make sure we set the identity for the Max puivot in case we dont bake the pivot and we dont transform the vertex with the absolute transform.

	[UE-31005] - Undo temp Hardware Survey API change from 4.10 - CL 2782817

Change 2986679 on 2016/05/23 by Alex.Delesky

	#jira UE-24747 - Importing FBX files that contain meshes that do not have non-degenerate triangles will no longer crash the editor on import, and will warn the user that the meshes are bad.

Change 2986798 on 2016/05/23 by Alex.Delesky

	#jira UE-31136 - Chord Input fields will no longer display the blinking edit cursor if they do not have focus.

	Fbx importer, fail import must not create a package in the content browser
	#jira UE-31154

	#jira UE-30988 - Changed the default window mode when launching a game from the .uproject file to Windowed

Change 2988708 on 2016/05/24 by Jamie.Dale

	Fix for crash when missing the fallback/last resort font

Change 2988782 on 2016/05/24 by Jamie.Dale

	Added the ability to version each localized string individually when loaded into the localization manager

	The single 32-bit global history has now been replaced with two 16-bit histories. One is global, and is updated whenever the culture is changed (or a LocRes file is loaded), and the other is local to each string, and is updated if the display string is changed outside of a culture update (to handle cases where the display string is changed, but the key is preserved). Changing the global history will reset all local histories.

	Because of the change from an int32 to a uint16, 0, rather than INDEX_NONE, is now considered the "unset" value for a history.

Change 2988856 on 2016/05/24 by Jamie.Dale

	Added a way to get the package(s) of the object(s) being edited by a property panel

	Typically the package is just the outermost of the object being edited, however there are some cases where this may not be the case:
	  - UMG widgets edit a transient copy of the real data, so we use the SetObjectPackageOverrides to override the package these objects should use to be the real asset package.
	  - Structs (UDS, Data Table, etc) don't have a way to get to their package, so you have to specify it on their FStructOnScope instance (see FStructOnScope::GetPackage and FStructOnScope::SetPackage). This has been hooked up for the UDS and Data Table editors.

Change 2988955 on 2016/05/24 by Alex.Delesky

	#jira UE-30645 - Adding in support for splash images to support .png and .jpg files. In general, this adds multi-extension support for external image references and external image picker modules.

	Git Request #2376

Change 2989418 on 2016/05/25 by Jamie.Dale

	Added a way to count text references within a package that match the given search criteria

	This can be used to detect whether a localization ID is unique within its package.

	The following search modes are available:
	  - MatchId: Detect a reference if it matches the given ID (ignoring the source text)
	  - MatchSource: Detect a reference if it matches the given ID and source string
	  - MismatchSource: Detect a reference if it matches the given ID but has a different source string

Change 2989436 on 2016/05/25 by Jamie.Dale

	Added "root-level" meta-data (meta-data associated with the package rather than an object within it)

Change 2989471 on 2016/05/25 by Alexis.Matte

	Fbx scene importer, fix naming clash when creating package we now also look in memory to find existing package not just on disk

Change 2989639 on 2016/05/25 by Jamie.Dale

	Added static version of FName::IsValidXName

	This allows you to verify name-like strings without having to convert them to an FName (and thus add them to the name table)

Change 2989716 on 2016/05/25 by Alex.Delesky

	#jira UE-30828 - The Standalone Session Frontend will now render the names of automation tests correctly instead of as solid white blocks.

	#jira UE-31177 - Attempting to export an entire level as an object file and choosing to export all materials as images will no longer crash the editor.

Change 2999709 on 2016/06/03 by Jamie.Dale

	Fixed some issues with gathering text from BP bytecode

	Bytecode in Blueprints is very volatile, and can only be safely gathered after it's been compiled (which is not guaranteed to have happened by the time we save the package). This change avoids caching any assets that contain scripts (non-data-only Blueprints), and instead will always load them to perform a gather (which will ensure the Blueprint bytecode is up-to-date due to compile-on-load).

Change 2999755 on 2016/06/03 by Richard.TalbotWatkin

	Fixes to Spline Mesh collision generation.
	- Fixed a serious issue with DDC ID generation, in that the static mesh wasn't forming a part of the key, hence any two spline meshes with identical properties but different meshes would yield the same cache entry.
	- Fixed how different collision boxes are transformed when rebuilding physics meshes. Convex collision transforms are now correctly taken into account, and spherical and capsule collision now gets correctly translated when a scale is applied to the start or end of the spline mesh.
	- Optimized physics rebuilding.  A new BodySetup object is now only created when needed, otherwise it is reused.

	#jira UE-31361 - Splines handle box collision and collision from other shapes differently

	#jira UE-30436 Refresh the property editor when a array element is added, remove, insert, delete and the property is favorite

Change 3004132 on 2016/06/07 by Jamie.Dale

	Fixed a hash conflict that could occur when both the case-sensitive and case-insensitive FName hashes were identical

	This resulted in the case-preserving FName being added to the head of the linked list for the bucket, which caused any subsequent name lookups to return that name index for the comparison index (since it matched an insensitive string comparison), rather than the name index of the first case-variant of that name that was added to the bucket.

	This change has new entries be inserted at the tail of the list, which ensures that enumeration for a case-insensitive name will always find the same entry in the bucket (the first one that was ever added) and will continue to compare correctly.

Change 3004286 on 2016/06/07 by Jamie.Dale

	Ensured that assignments that publish new names to the bucket are atomic

Change 3004310 on 2016/06/07 by Jamie.Dale

Change 3004381 on 2016/06/07 by Jamie.Dale

	FAsyncPackage now creates the meta-data before processing the remaining exports

Change 3006760 on 2016/06/08 by Jamie.Dale

	Added support for stable localization keys

	This feature adds support for preserving the existing key of an FText property when editing the source string, providing that it is the only reference to that string within the package. A side effect of this is that you're now able to specify custom keys for FText properties since we can now verify that the custom key won't cause an identity conflict.

	In order to limit the search domain for uniqueness to a single package, we've added the concept of a "localization namespace" to packages (stored in the meta-data). Each package is given a unique namespace, which is appended to the user-defined namespace of the text when it is modified, saved, or duplicated. This package namespace ensures that the same user-defined namespace and key may be used in different packages without causing an identity conflict.

	In order to access the package namespace within the Core code that hosts FText (which doesn't know about UPackage), FArchive now provides a GetLocalizationNamespace function to access the package namespace within the Core code, and a SetLocalizationNamespace function for CoreUObject and Engine code to pass down the package namespace from their packages.

	If you have an archive that handles duplicating objects into a different package, or duplicating packages themselves, then you'll want to make sure it's setting the package namespace correctly. FObjectReader and FObjectWriter have been updated to do this, and serve as a good example. FDuplicateDataReader (used by StaticDuplicateObject), and FCopyPropertiesArchiveObjectWriter (used when compiling Blueprints) have also been updated to set the package namespace, as they both handle copying objects between packages. TextNamespaceUtil provides a suite of functions for getting at (or setting) the namespace for a package.

	Keys will start to stabilize naturally over time once this feature is enabled, however the StabilizeLocalizationKeys commandlet may also be used to stabilize all the keys for a game at once. Running it for a game under source control would look something like this:
	  MyGame -run=StabilizeLocalizationKeys -IncludeGame -NativeCulture=en -EnableSCC

	This commandlet also updates your localization archives to use the new text identities, however you'll still need to run a localization gather and localization compile before the updated translations will be available for your game.

	Note: This feature is currently disabled via the USE_STABLE_LOCALIZATION_KEYS define. It will be enabled at a later date.

	#jira UETOOL-796

Change 3007501 on 2016/06/09 by Trung.Le

	#jira UE-31722
	Fix MaterialFunctions crash when editing text in Libraries Category Text field.

	PR #2459: Generate JSON for nested structs in DataTable rows (Contributed by jorgenpt)

Change 3008019 on 2016/06/09 by Jamie.Dale

	Updated structs to export as JSON when displaying them in the Data Table editor

	This produces much cleaner results than using the text export method (which will use the internal names for user defined structs).

	This also cleans up the FDataTableExporterCSV and FDataTableExporterJSON APIs so that you don't need to pass in a UDataTable if you're not going to use it.

	#jira UE-29958

Change 3008052 on 2016/06/09 by Jamie.Dale

	Fixed bug importing an array inside a JSON Data Table

	This was noticed when testing a GitHub PR, but the JSON importer for a Data Table was appending the new data to the array rather than replacing it. It now clears the array prior to importing.

Change 3013111 on 2016/06/14 by Jamie.Dale

	Unified the number, percentage, and currency formatting between the ICU and Legacy text implementations

	Removed all the old legacy number formatting code, and removed the calls to the ICU specific number formatting. Everything is now using FastDecimalFormat as this will allow some optimizations later when formatting numbers in FText::Format.

Change 3015438 on 2016/06/15 by Cody.Albert

	Fixing ScrollBy function to calculate new scroll offset based on the current scroll offset and not the current desired scroll offset (which may not be the same during an animation)

Change 3016782 on 2016/06/16 by Richard.TalbotWatkin

	Corrected ConvexHull2D so that it returns an empty set of indices when passed an empty points array.

Change 3016949 on 2016/06/16 by Jamie.Dale

	Added FastDecimalFormat overloads to write into an existing string

	This helps avoid an extra allocation if you already have a pre-sized string that you're writing the number to (as is the case in FText::Format).

Change 3016952 on 2016/06/16 by Jamie.Dale

	Changed an Add for an Emplace to avoid moving a temporary

Change 3016954 on 2016/06/16 by Jamie.Dale

	Updated some FText code to avoid creating temporary objects just to move data through a hierarchy

	There was some code in FText and its internal types that were using pass-by-value as a marshaller to move data through a hierarchy. This resulted in temporary objects being created and destroyed to facilitate the movement of data.

	This change has all the internal FText code (private FText constructors, internal text data, and internal text history) take its movable types as an r-value reference. This avoids the temporary objects, but also makes it impossible to accidentally copy a construction argument when you meant to move it (you can still copy, but the copy must be explicit).

	In addition to this, FText::FromString and FText::AsCultureInvariant now have two overloads, const FString& and FString&&, to avoid them creating a temporary when you're invoking a move. FText::ChangeKey now takes its parameters by const& as their data wasn't being moved further down the chain, so the by-value copy was wasteful.

Change 3019021 on 2016/06/19 by Richard.TalbotWatkin

	When deleting a brush, ensure geometry is rebuilt before updating the details panel according to the selection change, so that the old Surface Properties don't continue to appear.
	#jira UE-8966 - Surface Properties of a BSP remain in the details panel after the BSP is deleted

Change 3019022 on 2016/06/19 by Richard.TalbotWatkin

	Fixed issue where the Surface Properties category in the Details panel doesn't appear after selecting a surface on a Brush which has just been placed.
	#jira UE-31916 - Selecting an edge of BSP geometry then a face does not show Surface Properties while in Place mode
	#jira UE-31915 - Selecting BSP face does not show Surface Properties in Details

Change 3019025 on 2016/06/19 by Richard.TalbotWatkin

	#jira UE-32173

Change 3021145 on 2016/06/21 by Jamie.Dale

	Added support for text format argument modifiers

	These can be used to mutate a format argument before appending it to the resultant formatted string, and are applied to the preceding argument via a pipe, eg) "{Arg}|plural(one=is,other=are)".

	We provide a few of these by default:
	 - |plural(key=val,...)
	 - |ordinal(key=val,...)
	   Provides support for cardinal and ordinal plural forms, where key may be any of "one", "two", "few", "many", or "other", and val may be any optionally quoted string.
	 - |gender(masculine,feminine,[neuter])
	   Provides support for gender forms, where the 0th item is the masculine version, the 1st item is the feminine version, and the 2nd item is an optional neuter version. The values may be any optionally quoted string.
	 - |hpp(consonant,vowel)
	   Provides support for Hangul post-positions, where the 0th item is the consonant suffix, and the 1st item is the verb suffix. The values may be any optionally quoted string.

	Major changes:
	 - Exposed the ICU plural form handling via FCulture::GetPluralForm.
	 - Updated the FText formatting code to use an expression evaluator (to support the more complex expressions needed for the argument modifiers).
	 - Added FTextFormat to store a pre-compiled format expression. Re-using one of these if you're performing a lot of formats with the same FText will increase your performance (as around half of the FText::Format cost can be compilation, via an implicit construction of FTextFormat).
	 - Updated the FText::Format(...) family of functions to take their format string as FTextFormat, and take their arguments as FFormatArgumentValue. This allows us access to the real numeric types within the format code, but doesn't break the existing API as these types are implicitly constructible from the old parameters (FText).
	 - Converted text history to store their format string as an FTextFormat in-case they need to perform a re-format (this is still saved as an FText).

	Breaking changes:
	 - The rules for the escape token have been simplified, and there is an incredibly unlikely chance that this may affect some text:
	   - The ` character will now only escape a valid character (producing only the escaped character in the final string), or it will be ignored and inserted as a literal character, eg) "`{F" -> "{F", and "`F" -> "`F".
	   - Previously it would also remove the escape character when it followed { or }, eg) "{`" -> "{" and "}`" -> "}", rather than "{`" and "}`" like you might expect. It would also have previously removed a ` at the end of a string due to a parser bug.

Change 3021156 on 2016/06/21 by Jamie.Dale

	Updated LinuxToolChain to use the same output delegate for all of its actions when cross-compiling

	This avoids the compile and link actions being split into different batches.

Change 3023154 on 2016/06/22 by Jamie.Dale

	Ported over CL# 3018771 to the UE automation

	This fixes an issue where a downloaded PO file smaller than the one already on disk leaving a mix of both files on disk (rather than the existing file on disk being truncated).

Change 3023579 on 2016/06/22 by Jamie.Dale

	Expanded the Blueprint FormatText node to support numeric and gender types

	These are needed to correctly support the new plural and gender forms that can be used in format strings, as these require actual numeric/enum data to be passed into the format arguments, rather than pre-formatted text.

	Major changes:
	 - The FormatText node for Blueprints now uses PC_Wildcard as its pin type for format arguments instead of PC_Text.
	   - Any existing literal text argument data in the pin is hoisted out into a "Make Literal Text" node which is then connected to the pin.
	 - FFormatArgumentData has been updated to be variant on the data needed by Blueprints. It's now a less comprehensive and non-unioned version of FFormatArgumentValue.
	 - The version of FText::Format taking FFormatArgumentData has been deprecated as its usage was internal to Blueprints and we have much better ways to format text in C++. Any existing C++ using that (of which we have none internally) should be updated to use FFormatArgumentValue instead.

Change 3024994 on 2016/06/23 by Nick.Darnell

	UMG - Removing the DesignerWidgetTree, instead going to directly inject the widget tree into the partially constructed UUserWidget during design time, when refreshing the preview.  This avoids doing something a little dangerous and sketchy like updating the living class instance with a new designer tree that all new instances will begin biasing using.  Also making the preview widget explictly non-transactional as there's no reason to track changes to the preview, all the changes that need to be tracked should be on the template widget.  This should fix the crash in the widget designer when you Undo just after compiling the widget blueprint.

	Fixed some measuring issues with bi-directional text within a right-flowed document

	There were three main issues:
	  1) Measuring blocks was measuring visual glyphs rather than logical glyphs (this caused bad measures/wrapping and overlapped rendering).
	  2) The text layout would consider blocks visually contiguous without making sure the block flow direction matched the line flow direction (this caused bad highlights).
	  3) The text layout would fail to compensate for a non-contiguous block that had a flow direction different to the line flow direction (it was hard-coded for RTL in LTR, so broke for LTR in RTL - this caused bad highlights).

	UMG - The widget component now extends from UMeshComponent, it can have a custom material applied to it, in order to achieve cooler effects - like ignoring the depth buffer.

	#jira UE-32326 - Clicking on the "Install {compiler}" button when trying to create a new code class or code project will now not crash the engine if it fails to open the installation file for write, nor will it create multiple notifications if the button is pressed repeatedly.

	This also addresses a potential issue with static initialization order when it comes to adding TickableEditorObjects to its corresponding array, since it was wholly possible for a statically initialized TickableEditorObject to initialize itself and add itself to the tickable objects arra before the tickable objects array was initialized, causing that object to not get ticked at runtime and causing a crash when the editor was closed.

	Fix to SListPanel so that those with horizontal arrangement (i.e. from STileView) use the number of desired items instead of the number of actual items in order to calculate the desired size of the geometry.  This fixes the case where an STileView is contained within an SScrollBox.
	#jira UE-32195 - STileView no longer works correctly when placed inside of a SScrollBox

Change 3035951 on 2016/07/01 by Richard.TalbotWatkin

	Fixed issue when importing a brush, so that the brush is always validated (relinked), whether it be a static or dynamic brush. This is because the process of rebuilding a dynamic brush sets the link indices to signify FBspSurf indices from the UModel instead of FPoly indices (the FPoly::iLink member is overloaded in its meaning). Always forcing a relink correctly sets the linked list of coplanars.

	#jira UE-32424 - Added a safeguard to ensure that renaming a world that was duplicated from another world would not crash the editor if both worlds' lightmaps and shadowmaps were still active in memory, due to the editor attempting to rename identical textures from different packages to the same location.

	The actual fix to this issue was performed in an earlier CL, but this should prevent the editor from crashing if the issue returns.

Change 3044922 on 2016/07/11 by Nick.Darnell

	Slate/UMG - Working on better support for VR interactions with Slate widgets.  This change fixes a lot of issues with the way interaction works with slate widgets rendered in the virtual world.  Breakages, direct mouse interaction with widgets in the virtual world is no longer supported.  Those kinds of interactions must all use the WidgetInteractionComponent now, which by default works similar to the lasers in VREditor for interaction.  However - you can disable automatic hittesting, and instead provide a custom hitresult instead if you want to use screen tracing and act like you're just a mouse cursor that is supported.  Menu anchors now properly function inside of widgets in the virtual world.  Performance improvements - the viewport no longer arranges all 3d widgets every frame.  Additionally, Widget Components now support a whole bunch of methods for reducing how often they redraw to help control performance, they also support manual refresh.  This automatically works in tandem with the widget interaction component to request refresh whenever the widget interaction component is interacting with the widget, thus giving you a simple way to only redraw widgets that the user is hovering on top of.  Unrelated - this change also fixes Stop navigation commands not working with Next/Prev navigation - Wrap is still unsupported.

Change 3048892 on 2016/07/13 by Nick.Darnell

	UMG - Fixing a problem with the interaction component, it now does some basic intelligent ignoring of anything it's attached to - excluding widget components.  So it's easier to attach it to things that might be inside of a say a player collision capsule.  Also removing the 'Max Interaction Distance' from the widget component as that is no longer the arbitor of interaction distance.

	#jira UE-33250

Change 3049096 on 2016/07/13 by Trung.Le

	Slate - Fixing a small bug in the virtual user function - was preventing getting the same virtual user multiple times if it had already been created.  Adding an option to the widget component to control the focusabilty of the underlying slate window that's created to host the widget content.  Adding an option to the widget interaction component to control if it should be simulating mouse input at all - use this to effectively disable hit testing, and changing hover states and the like.
