Lit->Lumen
Added Lit->Lumen submenu with 4 view modes - Lumen Scene, Lumen Reflection View, Lumen Surface Cache and Overview:
* Lumen Scene - same as ShowFlags->VisualizeLumenScene. Visualizes Lumen scene representation in highest possible quality, with highest possible view distance
* Lumen Reflection View - Lumen Scene, but with current reflections settings. Basically represents how things look in the reflections
* Lumen Surface Cache - visualizes surface cache and marks with pink missing surface cache coverage
* Overview - 3 Lumen view mode tiles, overlaid on top of normal view
Show->Lumen
Added Show->Lumen submenu with 6 flags, which allow to disable specific trace types (screen space, detail, global, far field), disable secondary bounces (radiosity) and disable Screen Space Directional Occlusion.
Show->Visualize
Removed �Lumen Scene� (replaced by Lit->Lumen->Lumen Scene view mode) and �Lumen Global Illumination� (replaced by r.Lumen.Visualize.IndirectDiffuse) from
Advanced visualization modes are accessible through r.Lumen.Visualize.Mode, which overrides current Lit->Lumen-> settings.
Misc changes:
* Renamed VisualizeLumenScene* to LumenVisualize*
* Moved shared visualize parameters to LumenVisualize.h
* Lumen HWRT visualize now uses same ray footprint as SWRT visualize
* Replaced HALF_WORLD_MAX with Lumen::MaxTracingEndDistanceFromCamera and Lumen::MaxTraceDistance in preparation for the LWC WORLD_MAX changes

- Image exposure is locally adjusted by decomposing luminance of the frame into a base layer and a detail layer.
- Base layer contrast can be reduced while preserving detail.
- Support blending with gaussian blurred luminance as proposed in Advances in Real-Time Rendering in Games 2021.
- Controls in PostProcessVolume.
- r.LocalExposure cvar to control whether local exposure is supported.
- Visualization mode in "Show->Visualize->Local Expsoure". Multiple modes controllable using r.LocalExposure.VisualizeDebugMode.
- Bilateral grid generation not yet optimized. Optimization should include increasing depth of grid to match histogram size so that global histogram can be generated from grid.
- Added option to use mirror address mode in PostProcessWeightedSampleSum, since black border adds noticeable vignetting to the blurred luminance.

DR - [UE-44393] - The Canvas is using the Globalshaders for clearing but compilation is done asynconously at load time. Unfortunately there could be Code that uses a canvas to draw and cause this issue in between. There might be some plugins that do this. For now we need to wait and block for the shaqders to be compiled until we can allo the use of the canvas.

Change 3482012 by Simon.Tovey
Fixed issue when building distribution lookup tables where the final sample fell short of the max input time.
As sampling is done only over this range, under constant interpolation the final value was never actually sampled and so cut from the final optimized LUT.
#tests constant interpolation now works.

New AllowAsyncLoading flag for UTexture::CachePlatformData().
It allows to load the source texture data in the async task if the source bulk data was not yet loaded.
Data loaded that way is not sharable between tasks and will be discarded.
This is required because updating the source data is not thread safe.

Fix the Nvidia driver bug with the old reversebits fallback function - you need to use the native reverse_bits intrinsic or use some uint(ushort()) casts to get the compiler to do the right thing, which means injecting the reverse_bits function in MetalBackend not the HLSL (as it has no such type).

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 3073689 on 2016/08/02 by Ben.Woodhouse
Improved skin postprocess - support for full resolution, with diffuse/spec lighting combined into single RGBA (sharing chroma)
Full res lighting gives less temporal AA flickering, sharper diffuse and specular lighting in the surface (since this is now at full resolution), faster postprocessing if using a 64-bit rendertarget (on NV 980Ti).
Checkerboard rendering is controlled via the r.sss.checkerboard cvar. - 0 is off/full res, 1 is checkerboard, 2 is automatic based on scenecolor (non-checkerboard requires 64bit or more rendertarget w/separate alpha)
Tested/profiled on PC, PS4

Fix for UE-34241
Scene proxy ptr was being cached during a downcast.
Inside a call to CreateDynamicData, CheckMaterialUsage_Concurrent() was causing the scene proxy to be recreated an so the cached ptr was stale.
I've fixed the immediate issue but recreating the scene proxy here doesn't seem great. Maybe CheckMaterailUsage() should be rethought a bit.

Downsampled separate translucency uses a separate view uniform buffer with correct buffer sizes
* Fixes WorldPosition in downsampled translucency
* View uniform buffer parameters are now cached on the view, to allow recreating the uniform buffer without having to rebuild the entire struct. Currently used by global distance field, downsampled separate translucency.
* Fixed the downsampled translucency depth buffer being full res used together with a smaller color target, now they are both the downsampled res

Fixed lighting build failure from UMaterialInstanceDynamic assigned to a mesh that's being exported to Lightmass. The Swarm cache entry is created using the parent's guid, causing multiple MID's with the same parent to acquire a file handle multiple times which fails after the first.

I did the first part, lock some showflags to be 0 or 1 in SHIPPING
If this causes problems for some applications (e.g. using showflag as scalability which they shouldn't) the user needs to update the code.
or we remove the lock from that showflag.
For editor or non shipping features it's fine to use the SetSHOWFLAGNAME() calls, they become NOPS in SHIPPING.
This is a performance optimization (when used in inner loop) and prepares for removing more
