MAJOR FEATURES & CHANGES
============================
Change 4073167 by Krzysztof.Narkowicz
Added subsurface profile for eye shading model.
#jira none
Change 4073422 by Krzysztof.Narkowicz
Added dual specular for subsurface profile shading model.
#jira none
Change 4075278 by Krzysztof.Narkowicz
Fixed forward reflection/refraction rendering issues, which caused ShaderModels.Material.Refraction to fail.
#jira none
Change 4084231 by Krzysztof.Narkowicz
Dual specular - replace lobe spread with two separate roughness multipliers. Default material roughness is now replaced by an average lobe roughness in order to support non dual specular features.
#jira none
Change 4092798 by Matt.Collins
Some HDR refactoring.
Previously the DisplayOutput and ColorGamut were only set in GameUserSettings.
I added a Sink that checks the HDR enable. If it's toggled we apply the correct DisplayOutput and ColorGamut for the current platform (this way we get good settings even if you toggle via the console). These settings are still exposed via the console and can be set independently if the user wants.
Change 4096954 by Chris.Bunner
Added ShaderModelID as scene texture option and renamed existing value to ShaderModelColor to better reflect the internal code.
Change 4111285 by Brian.Karis
Eye shading update.
Added Iris normal (disabled). Removed wrap. Fixed contact shadows.
Change 4155261 by Krzysztof.Narkowicz
Planar reflection prefilter - use scene viewport size instead of reflection target size in order to keep filter size constant in screen space. This makes planar reflection filter more stable in case of dynamic resolution.
#jira none
Change 4167644 by Krzysztof.Narkowicz
Global shader map is now stored in multiple DDC entries (one per shader filename) instead of keeping everything in a single one. This allows to skip recompilation of unchanged shader files.
Change 4183727 by Yuriy.ODonnell
Implemented auto-conversion from deferred to DBuffer decals in forward shading mode (when GBuffer is not available).
Added support for specular and metallic channels for DBuffer decals, based on work by Chris Bunner.
This requires DBufferC to be expanded from 2 to 4 channels, leading to slight increase in DBuffer bandwidth and memory requirements.
Appearance of DBuffer decals is affected by this change, as specular and metallic channel values previously hard-coded in DBufferDecalShared.ush.
Decals were forced to be non-metallic and have specular of 4% (0.5 numeric value). Now the authored decal material values will be used, which matches GBuffer decals.
Added support for DBuffer decals with emissive component.
Most decal types can now be automatically converted, with the exception of stain decals. Those are currently approximated as regular translucent decals.
Change 4197684 by laz.matech
Added a PostProcess Volume test to the map to test that Cinematic Depth of View can be achieved through PPVs as well. Changed the BP_DepthOfFeildPOV asset - I exposed Focus Method so that it can be disabled for the PPV test. Added a second Hair Model head to the InFocusHair test so that it tests in and out of focus hair models (changed the name of the test to FocusHair).

#jira UE-59525
Change 4260154 by Mark.Satterthwaite
Parallelize the creation of Metal archives and libraries when they are broken up into smaller sub-libraries, this should reduce apparent cook time by going wide across threads on the host of the cooker.
Change 4270594 by Brian.Karis
Fix for textured rect light L pointing away from plane due to approximate diffuse integration.
Change 4273361 by Daniel.Wright
Particle Cutouts with 8 verts now always use stochastic approach. Circle textures with > 234 edges in the convex hull were overflowing the uint64 calculation of the total number of combinations, causing an infinite loop.
Change 4309174 by Mark.Satterthwaite
Graph device utilization from the driver monitor stats - really helps see how well the GPU is being used.

Optmizing RemoveUniformBuffersFromSource. Brings it from ~20% to ~1.5% in my testing.
#jira none

Fix from Stephen Hill for incorrect light grid culling near the near plane
Change 4314169 by Richard.Wallis
FShaderCache and associated public structures are now marked as deprecated. All FShaderCache code hooks removed from MetalRHI, OpenGLDrv and engine Launch/Shutdown logic.
#jira none
Change 4320760 by Arne.Schober
DR - Remove SV_Coverage from basepass interpolants when running with Masked in early Depth with ForwardShading as otherwise earlyZ will be disabled (as the PS has to run).
#jira UE-60992
Change 4334607 by Uriel.Doyon
Added custom overrides to reset ULightComponent::Intensity to default (in FLightComponentDetails).
Now settings a light Intesity to default resets the brightness to the archetype brightness.
This handles correctly cases where the intensity units differs between the two objects.
Also changed FLocalLightComponentDetails so that changing intensity units kepts the same brightness
(by recomputing the Intensity).
#jira UE-61401

Updated items from original shelved version by Mark Satt:
- Added MetalBackend.cpp to change main function string to have an initial crc + code length zero's
**Description below taken from Mark Satt's original verison of this in CL3343280**
Updated for Dev-Rendering's PSOs & integrates Richard's work on RHI shader libraries.
Replace the FShaderCache's cook-time binary shader cache with Dmitriy Dyomin's standalone FShaderCodeLibrary that saves all shader byte-code arrays to files named by the FSHAHash. This de-duplicates shaders so we only ever store the byte code once. Includes optional support for generating a platform specific library file - which Metal implements to provide a single Metal library. The platform-native implementation can perform more de-duplication and in the case of Metal has lower file overheads and will compress more efficiently.
- All of the support code for the FShaderCache's cook caching is gone, which affects all platforms. The FShaderCodeLibrary is currently supported by Cook-By-The-Book but can be used with iterate or child cookers - only DLC cooking requires further work.
- With further modifications it should be possible to support Cook-on-the-Fly as well (output directories would be needed in FShaderCodeLibrary::InitForCooking) and the file-access pattern should be changed to use async. IO so that Material loading is not considered complete until all required byte-code arrays are loaded into the FShaderCodeLibrary.
- For Metal archiving shaders this way will compile with debug information and the FShaderCodeLibrary, with some help from extensions to IShaderFormat, will save the debug information out into separate files during cooking - these can then be used to debug the game without having to locally recompile, recook & repackage but the shipped byte-code is stripped. Global shader caches are also subject to de-duplication in the library in order to support Metal's shader stripping.
- File Move operations need to respect the 'Replace' flag - for FShaderCodeLibrary to work we need Move to be atomic.
- This bumps the object version and will cause all content to recook.
- Native library support is optional - only Metal currently implements one, but so could Vulkan and D3D12. For Metal the big advantages are further de-duplication where different materials generate the same MetalSL text but a different FSHAHash, that the single Metal library has lower overhead and that as a single file it all compresses far better (esp. with LZMA - 5x smaller).
Change 3367854 on 2017/03/28 by Mark.Satterthwaite
Don't track or record draw call resources for non-OpenGL shader platforms in the shader-cache as it is unnecessary and makes it slower on the CPU than it needs to be.

Added flags in UPrimitiveComponent to keep track of its state in the streaming manager.
This allows to avoid unnecessary callback and processing in begin destroy reattach and being destroy logic.
Removed the limitation of only processing UMeshComponent when handling spawed primitive.
This releases the level manager from having to manage dynamic primitives.
This improves performance by not having to manage dynamic references in the level manager.
Primitives managed as dynamic now have a callback when ever their proxy is udpated, handling
many cases automatically where previously a manual callback to notify would have been required.
Fixed an issue where primitives with no reference to streaming textures would loose they dynamic state
because of lack of references in the streamer.

- This would reduce the Locking required as it's naturally per thread/context and only the final record would need a lock

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 3163562 on 2016/10/14 by Mark.Satterthwaite
Tidy up and extend the Metal debugging options:
- Added rhi.Metal.BufferScribble which when enabled will fill freed buffer regions with 0xCD to help identify any areas where we are writing to a buffer while it is still being processed on the GPU.
- Added rhi.Metal.BufferZeroFill which will zero-fill newly allocated buffer regions before any other data is read/written. Useful for catching cases where we might be reading uninitialised memory.
- Added rhi.Metal.ResourcePurgeOnDelete which will purge the backing store of resources prior to releasing them back to the system or the respective pool. This will make any use-after-free conditions much more likely.
- Added rhi.Metal.ResourceDeferDeleteNumFrames to defer releasing resources to the system or the resource pool by the specified number of frames (in addition to the current policy of waiting for the current end of frame & command-buffer completion). Useful for tracking down resource lifetime errors.
- Fixed a number of bugs related to the modifications to vertex stream handling and addition of the SetShaderBytes API.
- Track the start & end of FRingBuffer ranges - it appeared that the ring-buffer usage was invalid but it was in fact only my assumptions about the range that needed to be scribbled for rhi.Metal.BufferScribble. There is still the possibility that command-buffers that are implicitly parallelised by the driver may cause the ring-buffer range tracking to go awry - but with our data dependencies and the separation of the async. compute context I don't believe this is likely.
- Fix up the "nometalv2" flag so that we can disable the features only available on iOS/tvOS-10/macOS-10.12 on newer devices to save having to reboot all the time.
- Fixed the flickering geometry when enabling rhi.Metal.RuntimeDebugLevel=4 which breaks render passes into separate command-buffers - the occlusion query was waiting on the wrong command buffer in this case.
