MAJOR FEATURES + CHANGES
==========================
Change 2771498 on 2015/11/18 by Rolando.Caloca
DevRendering - HlslParser - Do not crash if an unknown preprocessor directive is found; add proper support for #pragma
#codereview Marcus.Wassmer
Change 2771600 on 2015/11/18 by Rolando.Caloca
DevRendering - SCW - Added support for running the platform shader compiler for one usf file off the dumped usf
Usage:
ShaderCompileWorker -directcompile FILENAME.USF -entry=EntryPoint -format=PCD3D_SM5/SF_PS4/etc -vs/-ps/-gs/-hs/-ds/-cs
-Also removed old communication enum from SCW
#rb Daniel.Wright
Change 2771647 on 2015/11/18 by Rolando.Caloca
DevRendering - HlslParser - Refactored removed unused outputs code in prep for reusing a lot of this code
- Entry point string now gets modified to the optimized one
- Fixed parser allocator when requesting pages bigger than PageSize
#rb Chris.Bunner
Change 2772133 on 2015/11/18 by Chris.Bunner
Removed physics shape type zeroing on Speedtree import. UE-23285
#rb Ori.Cohen
Change 2772225 on 2015/11/18 by Rolando.Caloca
DevRendering - Hlsl - Support for removing unused inputs on pixel shaders
- Fix some shadow variable warnings
#rb Chris.Bunner, Nick.Penwarden
Change 2772469 on 2015/11/18 by Daniel.Wright
Fixed SCW always exiting after compiling a long shader, now checks idle time starting from the end of the last compile task
Automated smoke tests aren't run in standalone programs which are frequently launched as they increase the startup time (doubles startup time of SCW as shown in sampling profile)
#rb Rolando.Caloca
Change 2772471 on 2015/11/18 by Daniel.Wright
Particle SubUV cutouts
* A new asset type 'SubUV Animation' precomputes bounding geometry for every frame of a SubUV texture animation.
* Particle emitters with a SubUV module can then use this SubUV Animation to render with much tigher bounding geometry to reduce overdraw.
* GPU performance savings depend on how much empty space (zero alpha) existed in the texture. Measured a reduction of 2-3x GPU time on a smoke effect.
* This only works if the material does not modify opacity to reveal areas with zero texture alpha

Filtering options on UnrealPak -list
#rb Josh.Adams
Change 2772644 on 2015/11/18 by Daniel.Wright
Integrate - Temporal AA dithering is only enabled if outputting to a low precision format
#rb Nick.Penwarden
Change 2773336 on 2015/11/19 by Rolando.Caloca
DevRendering - PS4 shaders - Added input/output attribute information when r.PS4StripExtraShaderBinaryData=0
#rb Marcus.Wassmer
Change 2773476 on 2015/11/19 by Rolando.Caloca
DevRendering - PS4 Shader attribute export stats
Run using r.PS4DumpExportStats 1 in the console

#codereview Marcus.Wassmer
Change 2773865 on 2015/11/19 by Gil.Gribb
UE4 - Added an FName churn tracker.
Change 2773900 on 2015/11/19 by Rolando.Caloca
DevRendering - Fix sharing shaders for material & mesh shaders
#rb Marcus.Wassmer
Change 2774277 on 2015/11/19 by Gil.Gribb
UE4 - Did minor optimizations to the PS4 RHI and drawlists.
Change 2774421 on 2015/11/19 by Olaf.Piesche
Fix#2 for UE-23325 - separate translucency materials don't show in static mesh editor
#codereview Martin.Mittring
Change 2774447 on 2015/11/19 by Rolando.Caloca
DevRendering - Velocity and Depth shader pipelines
#rb Marcus.Wassmer
Change 2774603 on 2015/11/19 by Marcus.Wassmer
Windowed vsync for ps4
#rb Rolando.Caloca
Change 2775650 on 2015/11/20 by Rolando.Caloca
DevRendering - Added two utility overloads per UDN suggestion
#codereview Gil.Gribb

Adding a new AutoExposure method
#rb Martin.Mittring
Change 2776345 on 2015/11/20 by Daniel.Wright
Capsule shadows for movable skylight
* Gathers capsule occlusion along the unoccluded sky cone computed by Distance Field Ambient Occlusion
* Requires DFAO to be enabled at the moment
* Some serious artifacts remaining in indoor scenarios, as the unoccluded sky direction is not continuous
Change 2777033 on 2015/11/22 by Uriel.Doyon
Enabled SceneTextures node validation when material domain is DeferredDecal

Change 2778618 on 2015/11/23 by Daniel.Wright
- Removed default shader platform parameter from GetGlobalShaderMap()
- Added an inline overload of GetGlobalShaderMap() that takes a feature level instead, and translates to the correct shader platform
- Cached feature level on FSceneView for faster access
- Cached shader map on FViewInfo for faster access
- Cached featurelevel/shadermap on rendering composition graph execution context, for faster access
Fixed a couple of crashes when switching feature level dynamically
- Needed to allow certain shader permutations to be generated if feature level was ES2, but still on a PC platform. (i.e. hitproxy shaders, and basepass shaders used by editor primitives system)
