Change 3310007 on 2017/02/17 by Chris.Bunner

	Back out CL 3221219 - causing MIC generation issues and superseded by CL 3273971.

	#jira UE-37792

Change 3310154 on 2017/02/17 by Chris.Bunner

	#jira UE-41823, UE-41950

Change 3310176 on 2017/02/17 by Chris.Bunner

	Merging CL 3233886: AMD HDR support (requires r.AMDSupportsHDRDisplayOutput=1 in ini).
	Update to AGS 5.0.5.
	Partial code tidy up.

Change 3310187 on 2017/02/17 by Chris.Bunner

	Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression.

	#jira UE-41594

Change 3310215 on 2017/02/17 by Chris.Bunner

Change 3333693 on 2017/03/06 by Daniel.Wright

	[Copy] Added 'r.AOListMeshDistanceFields' which dumps out mesh distance fields sorted by memory size, useful for directing content optimizations

Change 3333705 on 2017/03/06 by Daniel.Wright

	[Copy] Mesh distance fields are now 8 bit fixed point by default, but can be changed back to 16 bit floating piont with a project setting.
	* 8 bit uses half memory but introduces error for thin surfaces or large meshes.

Change 3333721 on 2017/03/06 by David.Hill

	DecalProxy:
	Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread.  This avoids  pointer chasing to the UDecalComponent (game thread component).

Change 3333772 on 2017/03/06 by Daniel.Wright

	[Copy] Scene motion blur data is only updated for the main renderer frames.  Fixes scene captures and planar reflections breaking object motion blur.

Change 3333790 on 2017/03/06 by Daniel.Wright

Change 3333836 on 2017/03/06 by Daniel.Wright

	[Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes.  They now use a 2d tiling mode which avoids the bloat, saving 96Mb.

Change 3333843 on 2017/03/06 by Daniel.Wright

	[Copy] Added OcclusionExponent to skylight component
	* Useful for brightening up indoors without losing contact shadows as MinOcclusion does

Change 3333869 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric Fog using a volume texture mapped to the camera frustum
	* Volumetric fog can be enabled on an Exponential Height Fog component with additional controls
	* Lights have a VolumetricScatteringIntensity
	* New cvars r.VolumetricFog, r.VolumetricFog.GridPixelSize, r.VolumetricFog.GridSizeZ, r.VolumetricFog.DepthDistributionScale
	* Lighting features supported:
	   * Directional light with CSM and a light function
	   * Point / spot lights without shadows / light functions / IES profiles
	   * Skylight with occlusion from distance fields
	* Analytical height fog covers the view range past where the volumetric fog ends
	* Temporal reprojection is used on the volumetric fog scattering and extinction to achieve stability
	* Translucency integrates properly into volumetric fog
	* Height fog StartDistance is not supported by volumetric fog and should be set to 0.

Change 3333894 on 2017/03/06 by Daniel.Wright

	[Copy] Initialize GDummyVolumetricFogGlobalDataUniformBuffer outside of parallel rendering

Change 3333908 on 2017/03/06 by Daniel.Wright

	[Copy] Volumetric materials
	* Added new material domain Volume, which can output Scattering, Absorption and Emissive.  All properties are in world space densities.
	* Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius
	* Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice.
	* Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely

Change 3334134 on 2017/03/06 by Daniel.Wright

	[Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

	#jira UE-40332

Change 3251141 on 2017/01/09 by Ben.Woodhouse

	Duplicated from Fortnite CL 3243458:
	D3D12 memory optimization -  The d3d12 buddy suballocator  is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory.

	On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage.

	Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX

Change 3251142 on 2017/01/09 by Ben.Woodhouse

	Duplicated from Fortnite 3243496
	memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time.

	Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways.
	The bound defrag is now done outside of the async work logic.

Change 3252866 on 2017/01/10 by Mark.Satterthwaite

	Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future.
	#jira UE-40357

Change 3254511 on 2017/01/11 by Rolando.Caloca

	DR - PSO stats

Change 3255958 on 2017/01/12 by Mark.Satterthwaite

	Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed.

	Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Change 3256371 on 2017/01/12 by Uriel.Doyon

	Added fastClamp to fastmath.usf

	Disabled bAffectDistanceFieldLighting on DefaultPawn, fixes VisualizeMeshDistanceFields in game

Change 3257112 on 2017/01/13 by Daniel.Wright

	DFAO optimizations
	* Changed the culling algorithm to produce a list of intersecting screen tiles for each object, instead of the other way around.  Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better.  3.63ms -> 3.48ms (.15ms)
	* Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms)
	* Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms
	* Compute shader for ClearUAV 3.04ms -> 2.62ms (.42ms)

Change 3257113 on 2017/01/13 by Daniel.Wright

Change 3257657 on 2017/01/13 by Daniel.Wright

	Mesh distance fields are stored zlib compressed in memory until needed for uploading to GPU
	* 81Mb of backing memory -> 32Mb in GPUPerfTest, atlas upload time 29ms -> 893ms

	Fix FMonitoredProcess to prevent infinite loop in -nothreading mode
	#jira UE-40717

Change 3260594 on 2017/01/17 by Daniel.Wright

	Added a new global distance field (4x 128^3 clipmaps) which caches mostly static primitives (Mobility set to Static or Stationary)
	* The full global distance field inherits from the mostly static cache, so when a Movable primitive is modified, only other movable primitives in the vicinity need to be re-composited into the global distance field
	* Global distance field update cost with one large rotating object went from 2.5ms -> .2ms on 970GTX and 4.6ms -> .3ms.  Worst case full volume update is mostly the same.
	* Adds 12Mb for the new volume textures

Change 3260956 on 2017/01/17 by Daniel.Wright

	Structured buffers for DF object data
	* Full global distance field clipmap composite 3.0ms -> 2.0ms due to scalarized loads

Change 3261296 on 2017/01/17 by Daniel.Wright

	Exposed MaxObjectsPerTile with 'r.AOMaxObjectsPerCullTile' and lowered the default from 512 to 256, saves 17Mb of object tile culling data structures
	Removed unnecessary UAV transitions preventing object and global cone tracing from overlapping, saves ~.1ms

	#jira UE-40841

Change 3264153 on 2017/01/19 by Ben.Woodhouse

	Integrate latest changes from MS-DX12 CLs 3231395-3262526

	- Added WinPixEventRuntime.tps
	- Includes PIX support, various optimizations (saved 1.3ms in testbed scene)

	CL 3262343:
	Fix depth testing on translucency not working correctly after cl 3231395. This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes:
	 - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case.

	CL 3231395:
	  Update D3D12 RHI:
	 - Fix deferred MSAA path in RHI
	 - Add Pix3.h support
	 - Cleanup SetName usage and remove it from shipping builds.
	 - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value.
	 - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64
	 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version.
	 - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident.

Change 3264251 on 2017/01/19 by Mark.Satterthwaite

	Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions.
	#jira UE-40803

	Changes to the FShaderCache to restore it and extend it to optionally report on shader de-duplication when generating a binary shader cache (Console Variable: r.BinaryShaderCacheLogging).

	Duplicate & amend CL #3266053 from Trepka:
	Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled.

	Amend & integrate RCO's CL #3197085.

Change 3267741 on 2017/01/23 by Rolando.Caloca

	Enabled r.Streaming.UsePerTextureBias by default as this has been tested in Orion for several months.
	Fixed issue with the  InvestigateTexture command which could return invalid reference depending on the timing,
	Added th MaxEffectiveScreenSize settings in the investigate texture command.

Change 3271594 on 2017/01/25 by Ben.Woodhouse

	ESRAM support stage 1:
	Implemented noncontiguous ESRAM page allocator replacing XgMemoryLayout API. The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range.
	Unlike the previous implementation, this allocator frees pages for reuse when resources are destroyed
	Note: issues with deferred deallocation may prevent reuse in many cases - that will be addressed in the next stage
	Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR

	#jira UE-36999

Change 3232641 on 2016/12/13 by Mark.Satterthwaite

	- Eliminate redundant state changes in MetalRHI in the state cache.
	- Add a new debug level for setting buffers to nil prior to calls to set*Bytes so that the tool doesn't display incorrect data.
	- Make testing for validation & statistics features use the same EMetalFeatures API as everything else for consistency.
	- Cache the fallback depth-stencil texture in the state cache and ignore it for determining whether a pass can restart - if we are using this texture its contents are worthless anyway.

Change 3232661 on 2016/12/13 by Mark.Satterthwaite

	Add Metal-specific permutations of TBasePassHS - they affect the C++ definition on all platforms but are only cached or used on Metal - because the way we compile the combined VS+HS tessellation stage requires that the combined VS + HS HLSL code references the same resources, otherwise we get incorrect resouce bindings and subsequently fail to render properly. Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine.

	Fixed ULandscapeComponent::GetUsedMaterials

Change 3237597 on 2016/12/15 by Ben.Woodhouse

	Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release.

	It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler.

Change 3238496 on 2016/12/16 by Marc.Olano

	Tone mapping fix for OR-31752, cherry picked from Orion 3208273

Change 3240163 on 2016/12/19 by Daniel.Wright

	Distance field self shadowing controls for hiding world position offset self-shadow artifacts
	* Removed static mesh build settings DistanceFieldBias, which shrunk the distance field, breaking AO and shadows
	* Added DistanceFieldSelfShadowBias, which prevents occlusion close to the surface only, maintaining shadows on the ground and AO on the ground

Change 3240271 on 2016/12/19 by Daniel.Wright

	Use 16 bit indices for distance field objects culled to tiles, when 16 bit will be enough.  Saves 10mb of tile culling buffers.

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.

	UE-28421 - Message box cannot be closed after accessing the home screen on iOS

	 + Implement a timeout when waiting for a reply after sending background/foreground/suspend events from the main thread to the game thread. This solves the immediate problem presented in the jira bug report, however, there are deeper issues with the consequences of blocking the game thread that are not addressed. Perhaps structuring the game thread loop to know about modal dialogs so that it can receive these events even when a modal dialog is up could be a better longer term solution

	Duplicate 4.12 CL #2974765: Workaround for UE-30069 - on Nvidia Macs we are breaking the GMux swap the second time we run the engine and it isn't clear why, so instead explicitly select the Metal device ourselves and don't allow the OS to swap the GPU driving the display. This will potentially reduce performance a little if the discrete GPU isn't already driving the display but until we know how we are clobbering the GMux/driver it is all we can do. This only applies to 10.11.5 with the default OS X drivers where there is more than one GPU in the system, earlier versions of OS X and the Nvidia WebDrivers are unaffected.

Change 2984874 on 2016/05/20 by Keith.Judge

	Xbox One - Re-enable shader DXBC intermediate bytecode stripping, except for geometry and hull shaders where there's a possibility of runtime recompilation in certain combinations. Saves ~2MB in TM-ShaderModels, will save more in larger maps.

	Further changes to ensure that UE-30710 really is fixed while also not live-leaking memory in MetalRHI.

Change 2986059 on 2016/05/20 by Mark.Satterthwaite

	Move the Metal uniform buffers into the same resource pool as all the other buffers and add stats for how many buffers are in the pool, how much memory is in use, free and wasted (due to aligned-buffer sizes).

Change 2986060 on 2016/05/20 by Mark.Satterthwaite

	Disable tiled-reflections on Nvidia & Intel Metal until they sort out the sample command on cube-arrays ignoring the lod level.

Change 2986063 on 2016/05/20 by Mark.Satterthwaite

	Missing change from previous CL.

Change 2986066 on 2016/05/20 by Mark.Satterthwaite

	Duplicate CL #2967998: Integrate - MaterialParameterCollections now create default resources (uniform buffers) which are used when no valid FScene is present (eg DrawTile while exporting materials to lightmass)
	#jira UE-31111

Change 2987591 on 2016/05/23 by Mark.Satterthwaite

	Remove usage of MTLRender/ComputeEncoder setSamplerState/s calls that take Min & Max Lod overrides - they currently don't work as expected on some GPU drivers and as we don't use them anywhere and I can't see that we will removing them costs us nothing and fixes tiled reflections on Nvidia with Metal SM5.

Change 2987679 on 2016/05/23 by Mark.Satterthwaite

	Re-enable tiled reflections on Nvidia by default now that they work.

Change 2987799 on 2016/05/24 by Mark.Satterthwaite

	Add a shader compile option "r.Shaders.ZeroInitialise" that we can turn on to force explicit zero-initialisation of local & temporary variables in hlslcc - so far only implemented for Metal. The default behaviour remains to omit zero-initialisation but the option is helpful to eliminate or track down uninitialised access in shaders that are causing real bugs (e.g. POM material relying on zero-initialised loop counters causing hangs/bad rendering on Mac).

Change 2989395 on 2016/05/25 by Lee.Clark

	PS4 - Fix shader output / render target format mismatch for sparse MRT.

Change 2990003 on 2016/05/25 by Jeremiah.Waldron

	When creating our own ConfigCacheIni in GetConfigCacheIni_APL, do not assume that the Engine ini was requested. Instead use the baseIniName passed to the function.

Change 2990393 on 2016/05/25 by Mark.Satterthwaite

	Back out changelist 2961310 - causes more problems than it solves. DistanceField rendering will still work on Intel Metal SM5  and may work on AMD but will be broken on Nvidia due to a bad access within the compute shader - there's no bounds checking in Metal...

Change 2990516 on 2016/05/25 by Brent.Pease

	 + UEPLAT-1294 - Support for local notifications
	 + UEPLAT-1254 - Add BP event for device orientation change
	 + Added a new class based on UGameInstance for mobile device callbacks

Change 2991361 on 2016/05/26 by Jeremiah.Waldron

	Move InAppPurchase class to StoreHelper.java so GooglePlay and Amazon store helpers can use it

Change 2992450 on 2016/05/27 by Mark.Satterthwaite

	Optional r.Shaders.BoundsChecking flag to control whether shader platforms should manually enforce buffer access bounds - HLSL returns zero or ignores invalid reads & writes but Metal leaves the behaviour undefined and some drivers then fail. By default this is off and its whatever the native platform behaviour is, enabling it will cost some amount of performance as the shader translator inserts additional instructions to try and match D3D as accurately as possible. This is required to fix GPU restart errors on some Metal drivers when using SM5 rendering features including DistanceField shaders.

Change 2993027 on 2016/05/27 by Mark.Satterthwaite

	Fix typo for new CFLAG_BoundsChecking enumeration value.

Change 2993594 on 2016/05/27 by Mark.Satterthwaite

	Build fix - check not assert...

Change 2993595 on 2016/05/27 by Mark.Satterthwaite

	Fix typo from Xcode hang...

Change 2993614 on 2016/05/28 by Mark.Satterthwaite

	At least for now enable shader zero-initialisation and bounds-checking on Mac to ensure that Metal shaders are compiled with semantics that approximate those HLSL assumes. This may cost some performance but will avoid a few GPU restarts on some vendor drivers.

Change 2993747 on 2016/05/28 by Mark.Satterthwaite

	Separate texture & buffer references in the Metal backend as they bind to separate arrays in the runtime to avoid giving the side-table buffer an innaccessible binding index. Also the side-table doesn't need to be emitted if no buffer SRV or UAV is used.

Change 2994256 on 2016/05/31 by Lee.Clark

	PS4 - Fix unitialized Head Position from HMD tracker when tracking fails. Fixes a problem with A3D audio not working.

	#codereview Chad.Taylor,Aaron.McLeran

Change 2994281 on 2016/05/31 by Rolando.Caloca

	DP - Allow hlslcc to process type casts containing the 'const' keyword

	#codereview chris.babcock, Peter.Sauerbrei

Change 2996441 on 2016/06/01 by Jeremiah.Waldron

	Relates to PR #2387: Adding ability to consume purchases during GooglePlay RestorePurchases (Contributed by gameDNAstudio)

	Missing changes from part 2 reworked so that there is still only one RestorePurchases function which takes the product IDs and consumable flags. I reflected this in StoreHelper so no casting is necessary in GameActivity and the soon-to-be-added AmazonStoreHelper in the GameCircle plugin will still work dynamically with GameActivity since it will call StoreHelper functionality rather than a GooglePlayStoreHelper specific function.

	Better categories for some Rendering project settings

Change 2982619 on 2016/05/18 by Daniel.Wright

	Scene capture 2d improvements

	Shorter display name for WorldPosition material node

Change 2984423 on 2016/05/19 by Daniel.Wright

	Fixed WorldPosition and ScreenPosition for downsampled separate translucency by scaling SvPosition before those computations.  The View uniform buffer still contains incorrect buffer sizes for this pass.

Change 2984432 on 2016/05/19 by Rolando.Caloca

	DR - Disable PPCombineLUT for Vulkan to work around glslang issue (will need to be reenabled when adding SM4/5 path)

Change 2985415 on 2016/05/20 by Daniel.Wright

	Hide DFGI show flags from UI

Change 2989901 on 2016/05/25 by Daniel.Wright

	Height fog now works properly in planar reflections
	* The ray used for computing fog is first clipped by the reflection plane

Change 2989904 on 2016/05/25 by Daniel.Wright

	Always use PF_FloatRGBA for LightAccumulation to guarantee alpha channel and negative range

Change 2989991 on 2016/05/25 by Daniel.Wright

	Improved usability for DBuffer Decals
	* 'Show Decals' works correctly, previously would fetch from uninitialized textures
	* DBuffer being enabled forces a full prepass, previously decals would render incorrectly unless correct settings of r.EarlyZPass were used
	* Improved the PrePass draw event to indicate whether it's full or partial
	* Materials using DBuffer blend modes will fail to compile when the DBuffer project setting is disabled, instead of just being invisible
	* r.EarlyZPass can now be changed at runtime, which is useful for profiling

Change 2990008 on 2016/05/25 by Daniel.Wright

	(Early work in progress)

Change 2990363 on 2016/05/25 by Daniel.Wright

	Spreading precomputed visibility to neighbors now uses a 2d grid to find neighbors, speeds up the process for 800k cells from 40 mins to 20s

Change 2990392 on 2016/05/25 by Daniel.Wright

	Added r.AOSpecularOcclusionMode, which determines how specular should be occluded by DFAO
	0: Apply non-directional AO to specular.
	1: (default) Intersect the reflection cone with the unoccluded cone produced by DFAO.  This gives more accurate occlusion than 0, but can bring out DFAO sampling artifacts.
	2: (experimental) Cone trace through distance fields along the reflection vector.  Costs about the same as DFAO again because more cone tracing is done, but produces more accurate occlusion.

Change 2990454 on 2016/05/25 by Martin.Mittring

	polish readme

Change 2990610 on 2016/05/25 by Martin.Mittring

	fixed building with VS2015, the right OpenSubDiv .lib files are missing, temporarily disabled the relevant code
	#code_review:Shane.Caudle

Change 2990754 on 2016/05/25 by Zabir.Hoque

	Fix compiler warning: C4456: declaration of 'NewStaticMesh' hides previous local declaration.

	#CodeReview: Martin.Mittring

Change 2990801 on 2016/05/25 by Zabir.Hoque

	Only allocate reflection capture cubemaps if we are actually doing a reflection capture. The old approach always allocated based on CVar and worked with a warning on D3D since if SRC was larger than the DST, the extra SRC area was dropped. New approach only allocates when necessary and is correctly sized everytime. Also hardened access to CVar and what users are allowed to set.

Change 2945365 on 2016/04/15 by Mark.Satterthwaite

	Assert if anyone calls RHIClearUAV on a structured-buffer or texture under Metal - there's no clear way to implement these cases yet.

Change 2945366 on 2016/04/15 by Mark.Satterthwaite

	Change the Metal parallel command-context submission to hand-off the entire NSArray of MTLCommandBuffers to avoid race conditions between one use of a context and the next.

Change 2945394 on 2016/04/15 by Mark.Satterthwaite

	Duplicate CL #2943702 from 4.11.2: Change the way Metal validates the render-target state so that in FMetalContext::PrepareToDraw it can issue a last-ditch attempt to restore the render-targets. This won't fix the cause of the Mac Metal crashes but it might mitigate some of them and provide more information about why they are occurring.

Change 2945444 on 2016/04/15 by Mark.Satterthwaite

	Cache the Metal fallback depth-stencil surface for the canvas tile rendering so that we only ever keep one spare depth-stencil surface around. This costs us a little more permanent memory but reduces churn.

Change 2945457 on 2016/04/15 by Mark.Satterthwaite

	Add validation code to MetalRHI to ensure that we don't erroneously re-clear existing render contents when restoring the render command encoder. This will only be active when the Metal debug layer is enabled and is completely compiled away in Test & Shipping builds for performance.

Change 2946249 on 2016/04/16 by Nick.Shin

	build HarfBuzz for HTML5

	#jira UE-28552 - HarfBuzz - HTML5

Change 2946250 on 2016/04/16 by Nick.Shin

	Rename/move file(s)

	move emscripten (part 1 of 2)
	from Engine/Source/ThirdParty/HTML5/emsdk
	to Engine/Extras/ThirdPartyNotUE/emsdk

	this is a request from legal

Change 2946251 on 2016/04/16 by Nick.Shin

	move emscripten (part 2 of 2)
	build scripts and cpp files updated with new emscripten path

	from Engine/Source/ThirdParty/HTML5/emsdk
	to Engine/Extras/ThirdPartyNotUE/emsdk

	this is a request from legal

Change 2946516 on 2016/04/18 by Mark.Satterthwaite

	Disable r.DFShadowScatterTileCulling  as well as r.AOScatterTileCulling  on Mac because we don't have the necessary RW textures on Metal.

Change 2947000 on 2016/04/18 by Michael.Trepka

	Print OS X version to log in FMacPlatformMisc::PlatformInit()

Change 2948197 on 2016/04/19 by Lee.Clark

	PS4 - Use SDK 3.508.031

Change 2948301 on 2016/04/19 by Nick.Shin

	upgrading zlib openssl libcurl libwebsockets

	part 1 of 2 -- adding new compiled versions (part 2 will be removing the old version -- which will be done after platform owners are given a chance to recompile for their platform - most notably: zlib)

	NOTE: Linux libraries are built for CentOS 6.7 (i.e. 2010 - glibc 2.12 and gcc 4.4.7)

	#jira UEPLAT-1246  -  Update libWebsockets
	#jira UEPLAT-1221  -  update websocket library
	#jira UEPLAT-1223  -  Arrange testing for 'update websocket library'
	#jira UEPLAT-1203  -  Add Linux library for libwebsockets
	#jira UEPLAT-1204  -  Rebuild libwebsockets with SSL

Change 2948319 on 2016/04/19 by Nick.Shin

	update zlib to v1.2.8

	part 1 of 4 - doing this in stages for tracking purposes

	#jira UEPLAT-1246  -  Update libWebsockets
	#jira UEPLAT-1221  -  update websocket library

Change 2948320 on 2016/04/19 by Nick.Shin

	update OpenSSL to v1.0.1s

	part 2 of 4 - doing this in stages for tracking purposes

	also, removing dynamic libs (for windows) -- these are no longer needed as this is now statically linked in editor
	- tested by installing perforce server setup with ssl access only and pointing editor source code to it as ssl:hostname:port
	- also tested trying accessing it without ssl which resulted in access denied indicating a successful test of dynamic lib removal

	#jira UEPLAT-1246  -  Update libWebsockets
	#jira UEPLAT-1221  -  update websocket library
	#jira UEPLAT-1204  -  Rebuild libwebsockets with SSL

Change 2948322 on 2016/04/19 by Nick.Shin

	update libwebsockets to v1.7.4

	part 4 of 4 - doing this in stages for tracking purposes

	#jira UEPLAT-1246  -  Update libWebsockets
	#jira UEPLAT-1221  -  update websocket library
	#jira UEPLAT-1204  -  Rebuild libwebsockets with SSL

Change 2948323 on 2016/04/19 by Nick.Shin

	VS 2015 libScePad support

Change 2948382 on 2016/04/19 by Mark.Satterthwaite

	Add Mac model, CPU string, num HTs to the log on Mac so that errors reported to us contain the data that Apple want when we turn them into bug-reports. Also added a missing sigaction from the trampoline.

Change 2948385 on 2016/04/19 by Mark.Satterthwaite

	Disambiguate Metal command-buffer failures by vendor & error type so that we don't end up with just one crash-reporting entry for many different kinds of crash and enable this assertion on all builds because it will always be fatal and failing to crash here may end up causing the Mac to reboot.

Change 2948460 on 2016/04/19 by Peter.Sauerbrei

	fix for wrong line endings

Change 2948526 on 2016/04/19 by Nick.Shin

	fix for wrong line endings

Change 2949334 on 2016/04/20 by Nick.Shin

	fix library path

	for some reason, NetworkFileSystem and HttpNetworkReplayStreaming on Mac platform needs full path - even though lib path was set...

Change 2949398 on 2016/04/20 by Lee.Clark

	PS4 - Fix SDK compile warnings

Change 2949656 on 2016/04/20 by Nick.Shin

	Back out changelist 2948320

	but keeping the C# build file as-is

Change 2949676 on 2016/04/20 by Mark.Satterthwaite

	Double-buffer the Metal viewport's back-buffer so that we can access the contents of the back-buffer after EndDrawingViewport is called until BeginDrawingViewport is called again on this viewport, this makes it possible to capture movies on Metal.
	#jira UE-29140

Change 2950025 on 2016/04/20 by Mark.Satterthwaite

	Undo CL #2949676 and instead on Mac where we want to be able to capture videos of gameplay we just insert an intermediate texture as the back-buffer and use a manual blit to the drawable prior to present. This also changes the code to enforce that the back-buffer render-target should never be nil as the code & Metal API itself assumes that this situation cannot occur but it would appear from continued crashes inside PrepareToDraw that it actually can in the field. This will address another potential cause of UE-29006.
	#jira UE-29006

Change 2950084 on 2016/04/20 by Nick.Shin

	OSX warning fix:

	UE4 supports down to OSX 10.9 rebuilt the zlib openssl libcurl and libwebsockets to support that

	build file also updated to use MACOSX_DEVELOPMENT_TARGET=10.9

Change 2950613 on 2016/04/20 by Dmitry.Rekman

	temp: update SSL dlls in Engine/Binaries/ThirdParty/OpenSSL/Win64

Change 2951556 on 2016/04/21 by Nick.Shin

	static libs double checked

	#jira UE-29674 - Editor fails to open in Dev-Platform

Change 2951559 on 2016/04/21 by Nick.Shin

	static libs double checked

	forgot these files - they were in another changelist

	#jira UE-29674 - Editor fails to open in Dev-Platform

Change 2951574 on 2016/04/21 by Nick.Shin

	remove unused variable warning

	was bughunt code...

Change 2951652 on 2016/04/21 by Josh.Adams

	- Disabled MRT support on iPad Air 1 devices, since it doesn't support wide enough MRTs that the engine needs (ie, only use MRTs in METAL_MRT mode on iOS)

Change 2951656 on 2016/04/21 by Josh.Adams

	- Fixed Mac compile error in Metal

Change 2951718 on 2016/04/21 by Nick.Shin

	PS4 - Fix staging and deploying of system prxs

Change 2953152 on 2016/04/22 by Mark.Satterthwaite

	Only cache instances of TShadowDepthVS  with bIsForGeometryShader=true when the RHI can handle the underlying feature. We can save memory on iOS by only emitting these shaders on Mac Metal or RHI's with Geometry shaders which have the required H/W to do this.

Change 2953385 on 2016/04/22 by Nick.Shin

	use HarfBuzz libs for HTML5

	c# build files updated to link in the harfbuzz libs

	#jira UE-28552 - HarfBuzz - HTML5

	#lockdown josh.adams

Change 2958724 on 2016/04/28 by Nick.Shin

	moved setting bVerifyPeer flag AFTER CertBundlePath has been set...

	otherwise, libCurl is going to try to verify the SSL session - but without a cert file, it makes no sense to try and verify the session

	- we could (and probably should) make this an error condition - but the constructor has the bVerifyPeer set to true -- which would mean that all games will need to have a cert file and/or know to set bVerifyPeer to false...

	- and so far, only linux and android seem to have code in place to make use of the cert files...

	#jira UE-29950 - Orion deticated server MCP authentication fails when using CURL
	#lockdown josh.adams

Change 2959058 on 2016/04/28 by Mark.Satterthwaite

Change 2960064 on 2016/04/28 by Dmitry.Rekman

	#codereview Chris.Wood, David.Vossel

Change 2963737 on 2016/05/02 by Dmitry.Rekman

Change 2964398 on 2016/05/03 by Mark.Satterthwaite

	Added GetCompressionBitWindow to IPlatformCompression so that FArchive compression can acquire the platform specific window value at runtime even without the Developer-only TargetPlatform modules. This allows the ShaderCache to perform runtime compression of preloaded shaders in-game without crashing.

b99d773644 Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces
* Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions.  A longer history filter is required to hide the jittering which can increase ghosting.
* The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage)
* A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result.
* The global distance field is composed of 4 128^3 clipmaps that follow the camera around
* Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost.  Worst case update cost (camera teleport) is 5ms on 7870.
* The global distance field currently breaks Distance Field GI
* Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.
