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 3055495 on 2016/07/19 by Marc.Olano
Allow Noise material node on mobile
No reason to exclude mobile, except for Fast Gradient Noise, which uses 3D textures. Allow this node on ES2 for all of the other noise functions.
#jira UE-33345
Change 3055602 on 2016/07/19 by Luke.Thatcher
Fix crash bug in D3D11 RHI when selecting adapters.
- Array of adapter descriptors will get out of sync with the adapter index if any adapter is skipped (e.g. the Microsoft Basic Render Device).
#jira UE-33236
Change 3055890 on 2016/07/19 by Daniel.Wright
Improved the assert in LoadModuleChecked so we won't have to check the log to see which module it was
Change 3055891 on 2016/07/19 by Daniel.Wright
Fixed Global Distance Field not dirtying previous object position on UpdateTransform - left behind a phantom shadow on teleports
* This will effectively double partial distiance field update costs until clipping of the update regions is implemented
Change 3055892 on 2016/07/19 by Daniel.Wright
Higher poly light source shapes drawn into reflection captures
Change 3055893 on 2016/07/19 by Daniel.Wright
More info to 'Incompatible surface format' GNM assert
Change 3055904 on 2016/07/19 by Daniel.Wright
Reflection environment normalization improvements
* Indirect specular from reflection captures is now mixed with indirect diffuse from lightmaps based on roughness, such that a mirror surface will have no mixing. Reflection captures now match other reflection methods like SSR and planar reflections much more closely.
* When a stationary skylight is present, Reflection captures are now normalized as if the initial skylight will always be present, giving consistent results with static skylight reflections. The skylight and reflection captures with sky removed used to be normalized separately, compacting the relative brightness between the sky and scene.
* Added r.ReflectionEnvironmentLightmapMixing for debugging lightmap mixing issues. This toggle was previously not possible due to prenormalizing the capture data.
* The standard deferred reflection path (r.DoTiledReflections 0) can no longer match the results of the compute path or base pass reflections, as it would require MRT to accumulate the average brightness
* Removed unused r.DiffuseFromCaptures
* Cost of reflection environment on PS4 increased from 1.52ms -> 1.75ms with this change, but decreased back to 1.58ms by reducing tile size to 8x8
Change 3055905 on 2016/07/19 by Daniel.Wright

Change 3062244 on 2016/07/22 by Daniel.Wright
Discard old prenormalized reflection environment data on load
Change 3062283 on 2016/07/22 by Daniel.Wright
MSAA support for the forward renderer
* AntiAliasing method is chosen in Rendering project settings, DefaultSettings category
* Deferred passes like shadow projection, fogging and decals are only computed per-pixel and can introduce aliasing
* Added Rendering project setting VertexFoggingForOpaque, which makes height fog cheaper and work properly with MSAA
* The AntiAliasing method in PostProcessSettings has been removed, this may affect existing content
* Added r.MSAACount which defaults to 4
* Integrated wide custom resolve filter from Oculus renderer, controlled by r.WideCustomResolve
* GBuffer targets are no longer allocated when using the forward renderer
* Decal blend modes that write to the GBuffer fall back to SceneColor emissive only
Change 3062666 on 2016/07/23 by Uriel.Doyon
Added legend to streaming accuracy viewmodes
Added a new helper class FRenderTargetTemp to be reused in different canvas rendering.
Exposed the pass through pixel shader so that it can be reused.

[CL 2967480 by Gil Gribb in Main branch]
- 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)
