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

Change 3012064 on 2016/06/13 by Nick.Whiting

	Merging Main -> DevVR

Change 3048060 on 2016/07/13 by Nick.Whiting

	Integrating CL 3045721 from //depot/Partners/Google/AndroidVR-DevVR
	Upgrade Android and iOS GVR SDK to the latest.
	Fix the flipped vignette issue when using Unreal's post processing distortion.
	Change the Daydream & Cardboard mode to use scanline racing.
	Deprecate the ability to turn off individual UI elements.

Change 3235307 on 2016/12/14 by Keli.Hlodversson

	Filter out excluded HMD modules during FEngineLoop:PreInitHMDDevice. The final selection still happens in UEngine::InitializeHMDDevice as all HMD plugins have not been loaded during PreInit

Change 3235308 on 2016/12/14 by Ryan.Vance

	#jira UEVR-478

	Monoscopic far field improvements

	Shader changes are now gated behind the read only cvar vr.MonoscopicFarField. Changing this requires a shader compile.
	Moved the mono rendering mode to the cvar vr.MonoscopicFarFieldMode. This is writable, so users can enable/disable mono rendering on the fly if the above cvar is enabled.
	Only write to the alpha channel in the mobile base pass if the object is opaque and MONOSCOPIC_FAR_FIELD is defined.
	Addressed code review comments.

Change 3235397 on 2016/12/14 by Keli.Hlodversson

Change 3257373 on 2017/01/13 by Keli.Hlodversson

	#jira UEVR-411: Finish renaming/removing/remodelling the remaining Oculus (Rift+GearVR) commands
	#jira UEVR-412: Rename and merge remaining Morpheus console commands
	#jira UEVR-417: Remove Exec from IHeadMountedDisplay

Change 3269971 on 2017/01/24 by Jeff.Fisher

	UEVR-498 move controller is missing world to meters
	UEVR-522 PS4 motion controller worldscale support.
	-Passing world to meters scale into getControllerOrientationAndPosition because the thing asking about it ought to be part of a world, and know what it should be.  This also avoids making PS4 motion controllers dependent on the HMD.  Note Google VR Controller doesn't do position, so doesnt' care about scale.  Oculus already had internal threadsafe tracking of world scale, so I left that.  Steam handles world scale below our input level.
	-Also adding PlayerIndex member to FSceneView so we can figure out which view the MotionControllerComponent should get its worldscale from for the late render thread update.
	#jira UEVR-498
	#review-3384107

Change 3288308 on 2017/02/06 by Jeff.Fisher

	UEVR-517 Detect MotionController Connectivity
	-PS4 can only track 2 controllers and 1 hmd.  Support for dealing with that is needed.
	-Also need to support multiple motion controller components mapped to a single controller.  Licencees have done that before.
	-Created a new interface IMotionTrackingSystemManagement, and implements it for PS4Tracker on PS4.
	-Created a MotionTrackedDeviceFunctionLibrary to expose that interface to blueprint.
	-With those one can enable and disable tracking on ps4 controllers and query their state to stay within the controller tracking limit.
	-PS4Tracker also keeps a blackboard of the enable/disable state so that one can enable or disable controllers that have not been connected yet, and have them enable tracking or not when they are connected.
	-DS4 controller no longer jumps back to 000 if it loses tracking.
	#review-3384107
	#jira UEVR-517

Change 3288309 on 2017/02/06 by Keli.Hlodversson

	Add file missing from CL#3257373.

Change 3288311 on 2017/02/06 by Jeff.Fisher

	UEVR-517 Detect MotionController Connectivity - Test content.
	-tm-motionControllers has a third mode where all playstation motion controllers for player 0 are availalbe.  You can toggle them to track or not with ctrl-P,G,L,R for pad, gun, leftmove, rightmove or with alt-P,G,L,R.  Ctrl tests doing so via MotionControllerComponent.  Alt tests doing so by player index and controller type enum.
	-ctrl-A disables tracking of all controllers
	-alt-A disables tracking of all controllers for player 0
	-ctrl-D toggles enabling new controllers by default
	-Also fixed one button not working in one of the other test modes for the Aim (gun) controller.
	-The controller 'models' have an arrow out the front.  It is black if disabled.  Red if enabled, but no tracker is active, yellow if tracked but inertial only, and green if fully tracked by the camera.
	-This logic is in the QA_MoCoAll blueprint.

Change 3291601 on 2017/02/07 by Jeff.Fisher

	UEVR-536 PSVR motion controller tracking problem with multiple controllers
	-Previous code called GetRelativeTransform from the render thread, but the game thread could update it at any time.  This caches that transform so that it can be safely used in the render thread.
	#jira UEVR-536
	#review-3384107 @Ryan.Vance

Change 3292460 on 2017/02/08 by Jeff.Fisher

Change 3311999 on 2017/02/20 by Keli.Hlodversson

	Create a default implementation for RecordAnalytics.

	Also create an initial stub for FHeadMountedDisplayBase for future default implementations of common HMD functionality.
	Make implementing IHeadMountedDisplay::GetDeviceName mandatory instead of defaulting to "Unknown"

	#jira UEVR-213

Change 3313467 on 2017/02/20 by Ryan.Vance

	#jira UE-41604

	3278583
	pCustomPresent->AllocateRenderTargetTexture may return false, if we blindly return true we can end up with an invalid render target since the fall back sceneviewport will be skipped.

	3278536
	Adding ovrError_NoHmd to our sanity check in OnStartGameFrame.

	* Pre VS2015 compilers don't like mixing wide and unmarked strings in concatenation. Unfortunately LOCTEXT hides the call to the TEXT macro, completely hinding the prefix (which only gets added to the first fragment.)
	* Switch apparently doesn't know how to format a size_t for analytics either.
	Also: Typo in backwards compatibility command name alias

Change 3337347 on 2017/03/08 by Jeff.Fisher

Change 3375480 on 2017/03/31 by Jeff.Fisher

	UEVR-9 PSVR: Social Screen Support
	-Experimental social screen support for 4.16.
	-This does the basics of driving output through the Aux port in the proper format for display on the mirror monitor.
	-Only supports 30fps on the mirror monitor.  60fps will require the implementation of sony system dialogs to deal with incompatable system features (video streaming, remote play).
	-There is a project setting in Morpheus, under experiemental bEnableSocialScreenSeparateMode.  This must be set to true to use this feature.  When it is false we avoid allocating the back buffers.
	-MorpheusFunctionLibrary blueprints now have a node "SetSocialScreenMode" which can switch between SystemMirror (hardware supported mirroring), SeparateTest (alternates black and white), SeparateTexture (displays a texture, eg a render target, specified via blueprint), and SeparateMirror(puts the hmd render buffer on screen - which is both eyes, like a debug mode).
	-Also finally updated the bEnabled flag in project settings to tell people it's only for PC.

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

Change 3219796 on 2016/12/02 by Rolando.Caloca

	DR - vk - Increase timeout to 60ms

Change 3219884 on 2016/12/02 by Daniel.Wright

	Assert to help track down rare crash locking capsule indirect shadow vertex buffer

Change 3219885 on 2016/12/02 by Daniel.Wright

	Fixed saving a package that doesn't exist on disk but exists in p4 at a newer revision when the user chooses 'Mark Writable'

Change 3219886 on 2016/12/02 by Daniel.Wright

	Don't create projected shadows when r.ShadowQuality is 0
	* Fixes crash in the forward path trying to render shadows
	* In the deferred path, the shadowmap was still being rendered and only the projection skipped, now all cost will be skipped

Change 3219887 on 2016/12/02 by Daniel.Wright

	Changed ClearRenderTarget2D default alpha to 1, which is necessary for correct compositing

Change 3219893 on 2016/12/02 by Daniel.Wright

	Level unload of a lighting scenario propagates the lighting scenario change - fixes crash when precomputed lighting volume data gets unloaded

Change 3220029 on 2016/12/02 by Daniel.Wright

	Async shader compiling now recreates scene proxies which are affected by the material which was compiled.  This fixes crashes which were occuring as proxies cache various material properties, but applying compiled materials would not update these cached properties (bRequiresAdjacencyInformation).
	* A new ensure has been added in FMeshElementCollector::AddMesh and FBatchingSPDI::DrawMesh to catch attempts to render with a material not reported in GetUsedMaterials
	* Fixed UParticleSystemComponent::GetUsedMaterials and UMaterialBillboardComponent::GetUsedMaterials
	* FMaterialUpdateContext should be changed to use the same pattern, but that hasn't been done yet

Change 3220108 on 2016/12/02 by Daniel.Wright

	Fixed shadowmap channel assignment for stationary lights which are not in a lighting scenario level, when a lighting scenario level is present

Change 3220504 on 2016/12/03 by Mark.Satterthwaite

	Metal Desktop Tessellation support from Unicorn.
	- Apple: Metal tessellation support added to MetalShaderFormat, MetalRHI and incl. changes to engine runtime/shaders for Desktop renderer and enabled in ElementalDemo by default (OS X 10.11 will run SM4).
	- Epic: Support for different Metal shader standards on Mac, iOS & tvOS which required moving some RHI functions around as this is a project setting and not a compile-time constant.
	- Epic: Fragment shader UAV support, which is also tied to newer Metal shader standard like Tessellation.
	- Epic: Significant refactor of MetalRHI's internals to clearly separate state-caching from render-pass management and command-encoding.
	- Epic: Internal MetalRHI validation code is now cleanly separated out into custom implementations of the Metal @protocol's and is on by default.
	- Epic: Various fixes to Layered Rendering for Metal.
	- Omits Mobile Tessellation support which needs further revision.

	Experimental Metal EDR/HDR output support for Mac (iOS/tvOS need custom formats & shaders so they are not supported yet).
	- Only available on macOS Sierra (10.12) for Macs with HDR displays (e.g. Retina iMacs).
	- Enable with -metaledr command-line argument as it is off-by-default.

	Fix a dumb copy-paste error from the HDR changes to Metal.

Change 3224220 on 2016/12/06 by Mark.Satterthwaite

	Fix various errors with Metal UAV & Render-Pass Restart support so that we can use the Pixel Shader culling for DistanceField effects.
	- Unfortunately Metal requires that a texture be bound to start a render-pass, so reuse the dummy depth-stencil surface from the problematic editor preview tile rendering.

Change 3224236 on 2016/12/06 by Mark.Satterthwaite

	IWYU CIS compile fix for iOS.

Change 3224366 on 2016/12/06 by Mark.Satterthwaite

	Simplify some of the changes from CL# 3224220 so that we don't perform unnecessary clears.
	- If the RenderPass is broken to issue compute or blit operations then treat the cached RenderTargetsInfo as invalid, unless the RenderPass is restarted.
	- This guarantees that we don't erroneously ignore calls to SetRenderTargets if the calling code issues a dispatch between two RenderPasses that use the same RenderTargetsInfo.

Change 3224416 on 2016/12/06 by Uriel.Doyon

	New default implementation for UPrimitiveComponent::GetStreamingTextureInfo using a conservative heuristic where the textures are stretched across the bounds.
	Optimized UPrimitiveComponent::GetStreamingTextureInfoWithNULLRemoval by not handling registered components with no proxy (essentially hidden game / collision primitives).

	Added blueprint support for texture streaming built data through FStaticMeshComponentInstanceData.

	Fix for material texture streaming data not being available on some cooked builds.

	Enabled split requests on all texture load requests (first loading everything visible and then loaded everything not visible).
	This is controlled by "r.Streaming.MinMipForSplitRequest" which defines the minimum mip for which to allow splitting.
	Forced residency are now loaded in two steps (visible, then forced), improving reactiveness.

	Updated "stat streaming" to include "UnkownRefMips" which represent texture with no known component referencing them,
	and also "LastRenderTimeMips" which related to timed primitives.
	Changed "Forced Mips" so that it only shows mips that are loaded become of forced residency.

	"Texture Streaming Build" now updates the map check after execution.

	Removed Orphaned texture logic as this has  become irrelevant with the latest retention priority logic.

	Updated "r.streaming.usenewmetrics" so that it shows behavior before and after 4.12 improvements.

Change 3224532 on 2016/12/07 by Uriel.Doyon

	Integrated CL 3223965 :

	Building texture streaming data for materials does not wait for pending shaders to finish compilation anymore.
	Added more options to allow the user to cancel this build also.

Change 3224714 on 2016/12/07 by Ben.Woodhouse

	Cherry pick CL 3223972 from //fortnite/main:

	Disable Geometry shader onchip on XB1. This saves 4ms for a single shadow casting point light @ 512x512 (4.8ms to 1.8ms)

	Scene Capture 2D can specify a global clip plane, which is useful for portals
	* Requires the global clip plane project setting to be enabled

Change 3226214 on 2016/12/07 by Daniel.Wright

	Improved deferred shadowing with MSAA by upsampling light attenuation intelligently in the base pass
	* If the current fragment's depth doesn't match what was used for deferred shadowing, the neighbor (cross pattern) with the nearest depth's shadowing is used
	* Edge artifacts can still occur where the upsample fails or the shadow factor was computed per-sample due to depth / stencil testing
	* Indirect Occlusion from capsule shadows also uses the nearest depth neighbor UV for no extra cost
	* Base pass on 970 GTX 1.69ms -> 1.85ms (.16ms) in RoboRecall

Change 3227635 on 2016/12/08 by Daniel.Wright

	Forward renderer supports shadowing from movable lights and light functions
	* Only 4 shadow casting movable or stationary lights can overlap at any point in space, otherwise the movable lights will lose their shadows and an on-screen message will be displayed
	* Light functions only work on shadow casting lights since they need a shadowmap channel to be assigned

	Fix Mac HDR causing incorrect output color encoding being used, HDR support is now entirely off unless you pass -metaledr which will enable it regardless of whether the current display supports HDR (as we haven't written the detection code yet). Fixed the LUT/UI compositing along the way - Mac Metal wasn't using volume LUT as it should have been, RHISupportsVertexShaderLayer now correctly returns false for non-Mac Metal platforms.

Change 3227705 on 2016/12/08 by Daniel.Wright

Change 3228940 on 2016/12/09 by Mark.Satterthwaite

	Editor fixes for 4.15:
	- PostProcessTonemap can't fail to bind a texture to the ColorLUT or the subsequent rendering will be garbage: the changes for optimising stereo rendering forgot to account for the Editor's use of Views without States for the asset preview thumbnails. Amended the CombineLUT post-processing to allocate a local output texture when there's no ViewState and read from this when this situation arises which makes everything function again.
	- Don't start render-passes without a valid render-target-array in MetalRHI.

Change 3228950 on 2016/12/09 by Mark.Satterthwaite

	Make GPUSkinCache run on Mac Metal - it wasn't working because it was forcibly disabled on all platforms but for Windows D3D 11.
	- Fixed the Skeleton editor tree trying to access a widget before it has been constructed.

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 3091951 on 2016/08/17 by Chris.Bunner

	(Duplicate) CL 3090919: Fixed edge case interactions in HLOD ray rejection logic in Lightmass.

Change 3093162 on 2016/08/18 by Ben.Woodhouse

	Fix minor memory leak (missing delete of RT Heartbeat thread)

Change 3093470 on 2016/08/18 by Ben.Woodhouse

	Fix minor leak in FMonitoredProcess - the Thread member would get leaked if the FMonitoredProcess was cancelled, because it gets NULLed without deleting it.  Fix is to add a bool to keep track of whether the thread is running, rather than using the Thread pointer.
	Also fixes a race condition where the FMonitoredProcess::Thread member could get initialized after the thread had completed. This would cause IsRunning to never return false, even if the thread has completed, and the editor would hang on startup (this was fixed by setting bIsRunning to true before creating the thread)

Change 3093698 on 2016/08/18 by Daniel.Wright

	Merging stereo planar reflections from Odin.

Change 3094060 on 2016/08/18 by Daniel.Wright

	Fully featured base pass reflection captures with blending and parallax correction
	* Used in the forward renderer when materials opt-in to 'High Quality Reflections'
	* Used in the deferred renderer for translucent 'Surface ForwardShading' materials
	* Reflection captures are culled to a frustum space grid using the same reverse linked-list method as lights in the forward renderer
	* Fixed grid culling in stereo / splitscreen
	* The ReflectionEnvironment compute shader used in the deferred path also uses the culled grid now which reduces its cost from .93ms -> .70ms on 970 GTX.  PS4 cost is about the same.
	* Capsule indirect self-shadowing is now reduced in the forward path to match deferred, and both are controlled by r.CapsuleIndirectShadowSelfShadowIntensity
	* SetupHZB is now skipped when SSAO / SSR / HZB are all disabled

Change 3098418 on 2016/08/23 by Olaf.Piesche

	Moving vertex factory dirtying to always happen in-editor for mesh emitters on dynamic data reinitialization; there are several cases in which this needs to happen (some material changes, mesh reimports...) which are difficult to track, so in-editor we just always recreate the mesh particle vertex factory with the dynamic data.

	#jira UE-34838

Change 3098448 on 2016/08/23 by Rolando.Caloca

	DR - vk - fixes for depth/stencil descriptors

	Lightmass area shadows only mark texels as mapped inside the light's influence, which fixes multiple stationary lights with bUseAreaShadowsForStationaryLight interfering.

Change 3098672 on 2016/08/23 by Rolando.Caloca

	DR - vk - Fixed crash when using vertex shaders with no descriptors

Change 3099173 on 2016/08/24 by Ben.Woodhouse

	Fixed various issues with subsurface profile, for checkerboard and non-checkerboard code paths

	- Re-enable non-checkerboard skin by default

	- Checkerboard issues fixed:
	    - Emissive lighting was being applied twice due to not taking checkerboard pattern into account
	    - Emissive lighting was modulated by basecolor in the recombine
	    - Metallic materials were contributing specular lighting to the diffuse channel

	 - Non-checkerboard fixes:
	    - Fix write mask during SkyLightDiffuse so alpha is updated correctly
	    - Metallic specular lighting was broken (specularColor was lerping to white instead of baseColor)

	 - Optimisation: Fall back to default lit for pixels where the opacity is 0.
	    - For non-checkerboard, this gives better handling of metallic/emissive for pixels where SSS is not required (non-CB RGBA encoding for diffuse/spec doesn't cope well with colored specular or emissive)
	    - For checkerboard, this gives similar results in terms of shading, but we get full-resolution shading on non SSS pixels

	#jira UE-34561

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

Change 3079316 on 2016/08/05 by Ben.Marsh

	Better PCH selection in ShaderFormatOpenGL and MetalShaderFormat - make sure Core is the first included header.

Change 3080579 on 2016/08/08 by Ben.Marsh

	Slate: Move DEBUG_TAB_MANAGEMENT into SDockingTabStack.h to remove circular include dependency with DockingPrivate.h.

Change 3080587 on 2016/08/08 by Ben.Marsh

	StandaloneRenderer: Move platform includes into a separate header so we can make individual headers self-contained, without having a circular dependency on StandaloneRendererPrivate.h.

Change 3080789 on 2016/08/08 by Ben.Marsh

	Move BuildGraph tasks for chunking, posting builds, labeling builds, and merging manifests into the MCP project. While we do provide public interfaces for this functionality, we don't currently expect anyone outside Epic to be using them.

Change 3080815 on 2016/08/08 by Ben.Marsh

	BuildGraph: Add a -GenerateDocs option, which writes out an HTML file constructed from C# XML documentation containing all the task information.

Change 3081374 on 2016/08/08 by Ben.Marsh

	UBT: Invalidate the makefile if any UHT headers are deleted. Should fix issue where files are moved from one module to another, and the original module no longer contains any generated headers. Its include path needs to be removed from the compile environment.

Change 3083152 on 2016/08/09 by Ben.Marsh

	PR #2667: Add Intel C++ Compiler support to Windows build (Contributed by JeffRous)

Change 3084039 on 2016/08/10 by Ben.Marsh

	BuildGraph: Add additional markup for parameter attributes. Also improve some documation.

Change 3084240 on 2016/08/10 by Ben.Marsh

	Plugins: Allow plugins in the project folder to replace plugins in the engine folder with the same name. Prohibit multiple plugins with the same name at other times.

Change 3084337 on 2016/08/10 by Ben.Marsh

	UBT: Specify the -precompile option when generating project files for a target, so we include all valid modules for intellisense.

Change 3085594 on 2016/08/11 by Ben.Marsh

	Change modules which reference a public header for their PCH to use a private PCH instead, even if it just includes the public header for now.

Change 3085999 on 2016/08/11 by Ben.Marsh

	Add some missing #pragma once directives.

Change 3086146 on 2016/08/11 by Ben.Marsh

	Core: Move prototype and linkage specifier for ConsoleCommandLibrary_* functions into header matching cpp file.

Change 3086172 on 2016/08/11 by Ben.Marsh

	Fixup some C-style header guards to use #pragma once instead.

Change 3087289 on 2016/08/12 by Ben.Marsh

	Split out UPackage and UMetaData into their own headers (they're already implemented in separate CPP files)

Change 3087310 on 2016/08/12 by Ben.Marsh

	Move method stubs for FNullSlateSoundDevice into a CPP file, since they're exported from the SlateCore module.

Change 3087341 on 2016/08/12 by Ben.Marsh

	UdpMessaging: Move PCH before #if PLATFORM_DESKTOP; it will only be defined if the definition is included.

Change 3087457 on 2016/08/12 by Ben.Marsh

	Core: Reorganize the FTransform and FMatrix headers: Transform.h now includes TransformNonVectorized.h or TransformVectorized.h as appropriate, and UnrealMatrix.h is now Matrix.inl (and included from Matrix.h).

Change 3088407 on 2016/08/13 by Ben.Marsh

	Replace use of Windows SIZE_T define with the regular C++ size_t.

Change 3088416 on 2016/08/13 by Ben.Marsh

	Include a header from all .generated.cpp files (GeneratedCppIncludes.h) which includes all the basic types required to compile them, rather than assuming that the module PCH will include everything.

	Also include the real declarations of noexport classes in Object.h (now renamed to NoExportTypes.h for clarity) when the CPP macro is defined, so the .generated.deps.h file will automatically have the correct definitions for them at compile time rather than relying on them being in the private PCH.

	Finally, rename UObject.h to Object.h for consistency with the naming convention for all other UObject classes. UObject.h still exists for now, but outputs a deprecated message if included.

Change 3088544 on 2016/08/14 by Ben.Marsh

	Core: Move the definition of the TEXT() macro into Platform.h, to avoid having to include OS headers to get it.

Change 3088552 on 2016/08/14 by Ben.Marsh

	Fix compile errors for some modules that don't already include CoreUObject.h.

Change 3088925 on 2016/08/15 by Ben.Marsh

	Remove circular include dependencies from VulkanRHI.

Change 3088926 on 2016/08/15 by Ben.Marsh

	Remove duplicate definition for WITH_FIXED_AREA_ENTERING_COST from EngineDefines.h - always uses the definition from DetourNavMeshQuery.h instead.

Change 3088930 on 2016/08/15 by Ben.Marsh

	Remove circular include dependency from PhysX.

Change 3088935 on 2016/08/15 by Ben.Marsh

Change 3088965 on 2016/08/15 by Ben.Marsh

	Add private PCH to Landscape, MoviePlayer, TaskGraph, XAudio2 and RealtimeProfiler modules.

Change 3088966 on 2016/08/15 by Ben.Marsh

	Engine: Move CPP files out of public header directories.

Change 3089520 on 2016/08/15 by Ben.Marsh

	BuildGraph: Change documentation command to output markdown.

Change 3090299 on 2016/08/16 by Ben.Marsh

	D3D12RHI: Move around some implementations to fix circular header dependencies which are masked by delayed template instantiation.

Change 3090303 on 2016/08/16 by Ben.Marsh

	Engine: Add a template specialization for TPointerIsConvertibleFromTo<AActor, const volatile UObject> to fix dependency on complete AActor definition for static assert in TWeakPointer<AActor>, which only appears if including Level.h without Actor.h. Delayed template instantiation usually masks this issue.

Change 3091861 on 2016/08/17 by Ben.Marsh

	Remove circular header dependencies, and fix ambiguous include paths in OSVR.

Change 3092068 on 2016/08/17 by Ben.Marsh

	Moving VulkanDynamicRHI into its own header.

Change 3093133 on 2016/08/18 by Ben.Marsh

Change 3093147 on 2016/08/18 by Ben.Marsh

	UBT: Add an error message when attempting to do a single-file compile with the wrong target selected.

Change 3093228 on 2016/08/18 by Ben.Marsh

	Remove redundant setting for remote server name from XML config, and set it to a valid machine in the engine config.

	UE-23925
	Clamping noise tessellation for beams at a high but sensible value; also making sure during beam index buffer building that we never get over 2^16 indices; this is a bit hokey, but there are so many variables that can influence triangle/index count, that this is the only way to be sure (short of nuking the entire site from orbit).

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

Change 3028958 on 2016/06/27 by Ben.Woodhouse

	Fix for perf issue with GetSingleFinalDataConst

	This was caused by the LPV integration/switch to blendables. Now we cache the flag for the directionalocclusion in the LPV class. This reduces calls to GetSingleFinalDataConst on the blendable data (potentially slow), and makes things a bit cleaner and consistent.

	Tested in QAGame editor (with LPV enabled in ConsoleSettings.ini)

	#jira UE-26179

Change 3029401 on 2016/06/27 by Rolando.Caloca

	DR - More vk logging

Change 3029549 on 2016/06/27 by Uriel.Doyon

	Refactored "r.OnlyStreamInTextures" into "r.Streaming.FullyLoadUsedTextures", making it fully load every used textures, as an alternative to disabling texture streaming.
	New options "r.Streaming.UsePerTextureBias" that assign a  bias between 0 and MipBias to each texture in order to fit in budget.
	Fixed crash when disabling texture streaming.
	Fixed issue when disabling texture streaming that would make current loaded texture low res.
	New logic to prevent retrying to cancel a streaming request more than once.
	Pending load request of one extra mip will not be cancelled anymore.
	Changed UTexture2D from float to double. Also using FApp::GetCurrentTime() instead of FPlatformTime::Seconds().
	#jira UE-32197
	#jira UE-31102

Change 3029837 on 2016/06/27 by David.Hill

	Fixed Shutter SM4 not working when using compute shader eye-adaptation

	#jira UE-31238

Change 3030607 on 2016/06/28 by Marc.Olano

	Random Number generators: fixed bug in TEA, added integer and float Blum-Blum-Shub. BBS is way cheaper for similar quality, suggest it for future use.

Change 3030627 on 2016/06/28 by Ben.Woodhouse

	Fix for warning. CVar naming scope clash (doesn't appear to happen in vs2015).

Change 3030809 on 2016/06/28 by Marc.Olano

	Noise shader function rename & perf improvement.

	Due to incorrect terminology in internet soruces, previous "Perlin" noise was not, in fact, Perlin noise. Now more accurately called "Value" noise. 6x perf improvement for value noise by changing random number function to BBS. Also updated instruction counts in UI tooltips.

Change 3030850 on 2016/06/28 by Marc.Olano

	Rename & redirect noise material enums. At some point these got switched around and no longer accurately described the noise options the selected. Redirect, so all existing content will continue to work as-is. Updated UDN docs to match.

Change 3030981 on 2016/06/28 by Rolando.Caloca

Change 3035577 on 2016/07/01 by Marc.Olano

	Tiling noise. Adds tiling option for gradient, gradient texture, and value noise in the noise material node. Tiling is more expensive, but allows noise functions to be baked into a seamless repeating texture.

Change 3035587 on 2016/07/01 by Ben.Woodhouse

	Fix for async SSAO bug (SSAO Async Compute results are used before the async job wait)

Change 3036935 on 2016/07/04 by Simon.Tovey

	Removing Data Objects

Change 3036942 on 2016/07/04 by Ben.Woodhouse

	Fix for decal rendering resource leak

	The cause was that FD3D11BoundRenderTargets doesn't support setting RTs sparsely. So if one element is NULL, it won't release the ones after it.

	The sparse RT layout happened as a result of a change back in October, which meant that GBuffers for decals could be set sparsely, dependent on whether the decal wrote to the normalbuffer

	This change adds support for sparsely bound rendertargets in FD3D11BoundRenderTargets.

	#jira UE-32602

Change 3037563 on 2016/07/05 by Chris.Bunner

	#Jira UE-31710

Change 3039454 on 2016/07/06 by Simon.Tovey

	Moved all Niagara files from Engine and UnrealEd to remove dependancies and increase compile times.
	Niagara is now 99.999% decoupled from engine and editor so development should be much streamlined.

	Plus a few other edits to remove Curves/DataObjects that I missed in last CL.

	Fixed non-directional DFAO occlusion on specular 'r.AOSpecularOcclusionMode 0'
	Skylight occlusion tint now applies to specular
	Skylight occlusion tint on diffuse is now correctly affected by DiffuseColor

Change 3039960 on 2016/07/06 by Daniel.Wright

	Forward renderer initial implementation
	* Point and spot lights are culled to a frustum space grid, base pass loops over culled lights.
	* Light culling uses a reverse linked list to avoid a per-cell limit, and the linked list is compacted to an array before the base pass.
	* New cvars to control light culling: r.Forward.MaxCulledLightsPerCell, r.Forward.LightGridSizeZ, r.Forward.LightGridPixelSize
	* A full Z Prepass is forced with forward shading.  This allows deferred rendering before the base pass of shadow projection methods that only rely on depth.
	* Dynamic shadows are packed based on the assigned stationary light ShadowMapChannel, since stationary lights are already restricted to 4 overlapping.
	* GBuffer render targets are still allocated
	* Fixed several issues in parallax corrected base pass reflections - not blending out box shape, discontinuity in reflection vector, not blending with stationary skylight properly
	* Forward shading is now used for TLM_SurfacePerPixelLighting translucency in the deferred path
	* Notable missing features: shadowing of translucency, support for various translucency lighting modes, multiple blended reflection captures

	Skylights aren't captured until their level is made visible- fixes the case where skylights capture too early

Change 3040316 on 2016/07/06 by Daniel.Wright

	PerObject shadows from point / spot lights do the light source pull back based on subject box size, not subject radius, since the box is used to find a valid < 90 degree projection.  Fix from licensee

Change 3040361 on 2016/07/06 by Daniel.Wright

	* Binding and outputting to GBuffers is disabled when using simple forward shading, along with dependencies of the GBuffers
	* Specular, normal maps and the 3rd SH band of skylighting are all hardcoded off.  Materials are forced fully rough.
	* Enabled with 'r.SimpleForwardShading 1', which can be changed at runtime
	* Added r.SupportSimpleForwardShading, which determines if the necessary shaders are compiled
	* Removed r.SimpleDynamicLighting, whose functionality (unshadowed directional light in the base pass) is a subset of simple forward shading, and was unused
