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 2920745 on 2016/03/24 by Uriel.Doyon
Texture streaming build now takes into account the material texcoord scales applied to the texture sampling.
Also finds out which texcoord is being used when sampling textures (between 0 and 3 currently).
TexCoord analysis debug view shaders is now working with SM4 ane SM5.
StaticMeshComponents hold persistent data coming from the texture streaming build.
#tests tested with different Paragon assets. Editor SM4 & SM5. Cooked maps

Distance Field Specular Occlusion
* Prototype - disabled by default
Change 2921681 on 2016/03/24 by Daniel.Wright
UnmappedTexelsPercentage is now 100 based
Change 2921682 on 2016/03/24 by Daniel.Wright
Planar reflections
* New actor and component
* The scene is rendered to texture with a mirrored camera and a clip plane each frame
* The reflection texture is then applied to opaque pixels in a deferred pass, with distance and angle from plane fades
* Translucent materials apply the nearest reflection plane in the base pass
* Planar reflections require the project setting 'Support global clip plane for Planar Reflections' to be enabled, since writing to SV_ClipDistance all the time adds about 15% BasePass GPU time on PS4
* Fixed global distance field in materials which had been broken since moving global distance field properties into the view uniform buffer
* Fixed PS4 removing system-value semantics when output from vertex shader and not read in next stage
Change 2921734 on 2016/03/24 by Uriel.Doyon
