MAJOR FEATURES & CHANGES
============================
Change 3658809 by Chris.Bunner
Changing default HDR display gamut to P3 as in practice that's more common than Rec2020, this should be a user-facing option where possible though as we can't automatically retrieve that data.

Change 3697488 by Richard.Wallis
Fix for Mac editor session no longer accurately tracking Mouse location after moving between Desktops in Mission Control on 10.12.6. Problem stems from the extra call to update the slate cached window position in mouse move while dragging, which is itself is a hack but apparently this is needed as we don't get window position updates on Mac while dragging (although I couldn't see any -ve side effects without it) then the OS (in 10.12.6) doesn't always push out a final window did move notificaiton when changing desktops which leaves the window according to slate incorrectly positoned to it's frame.
Solution is to either remove the mouse-move-while-drag window position hack or add a final window position update to the mouse-up event while dragging - this change is the latter.
#jira UE-37553
Change 3697501 by Richard.Wallis
Move audio processing over to audio bus tap. Currently on Mac Media audio playback uses OS media player mixer rather than Engine as existing implemtation, using AVAssetReader, now suffers from poor performance with new Media Framework. This audio tap version replaces that asset reader implementation but also suffers from bad quality audio hence is still disabled at the top of AvfMediaTracks.cpp.
Original Code Review Description:
Convert Mac to Play audio through the engine MediaFramework API rather than using AVMediaPlayer. This is the Mac implementation only - this should work ok on iOS but unable to test due to missing audio type implementation (throws error "Init Buffer on unsupported sound type name = Synth type = 5"), as such is only enabled for Mac. There maybe some extra tweaks required for iOS on app backgrounding etc if this feature is enabled.
- Stuttering Audio Performace issue investiagation: Re-Tested this implementation against [now fixed] current Mac implementation which was working fine last year and that implementation now has the same audio output quality (performance) issues as this one. Basic investigation seems to point to somewhere in the engine audio handing. When poor audio is heard the FMediaAudioResampler::Generate() function is dequeing an IMediaAudioSample sample buffer and the audio sample queue usually has 50-100 of these IMediaAudioSample buffers waiting in the queue. I think the AvfMedia playback system is providing the sample buffers in good time but they are not getting consumed "fast" enough. This under consuming also occurs if I force the Core Audio - Audio Unit mixer to use 48000 samples/sec.

Ignore per view automatic mip bias on texture type other than 2d textures.
#jira UE-51396
Change 3702297 by Richard.Wallis
Mac compile fix for nullable specifier. Looks like Obj class using the C++ class also needs this otherwise it throws. Seems to be some kind of xcode/compiler caching bug with this stuff as it'll report the error once then on subsequent compiles say everything is ok.
#jira UE-51386

DR - Debug label on D3D11 UAVs

Change 3705000 by Chris.Bunner
Skip compiling opacity and opacity mask inputs on opaque surface materials. Previously the code was always added to the shader, sometimes we force opaque materials down a masked path which then calls the dormant code unintentionally. A safer fix for UE-48254.
Partially reverted previous fix in CL 3608303 which removed a material instance optimization caching the overridden base properties.
Change 3706065 by Guillaume.Abadie
Does some renaming for primary screen percentage, and move the primary screen percentage method selection from dynamic resolution driver to FSceneView.

Change 3706650 by Gil.Gribb
UE4 - UE4 - Changes from intel. Increase number of worker threads on Windows to if hyperthreads (hyperthreads √ 2) else cores √ 1 up to a max of 22 workers. Increase MAX_THREADS multiplier per bank from 22 to 26. Intel VTune ITT event annotations. Wrapped in same function as your existing CPU events and enabled with √vtune. Optimize NV cloth by consuming FVector instead of FVector4 out of the solver. Vertex buffers were using FVector all along. ~15% improvement. Optimize cloth copy to vertex buffer by adding prefetch (similar to how bones are already done). Move local to world cloth transform from CPU to GPU. When simulating lots of vertices game thread was becoming bottleneck doing matrix multiply. Add your TaskGraph task switch latency test code.

Change 3710454 by Mark.Satterthwaite
Refactor the way we compile Buffer<> & RWBuffer<> types for Metal so that we can support the type-conversion semantics of HLSL/D3D.
- Buffer<> types are converted to Linear Textures unless the internal type is 3-compnent or the STRONG_TYPE macro is added as a type-qualifier. Linear Textures require an MTLTexture "view" object be created around the MTLBuffer which is the backing-store and it is typically best if that buffer is marked as Private (GPU-only) memory, reading from this in the shader then uses the texture-fetch hardware to perform the format conversion on load.
- RWBuffer<> & 3-compnent Buffer<> types are converted to use template functions to load/store - the implementation of which will read the format from the BufferSizes meta-table and determine which type-conversion to apply. Function-constants are used to specialise the shader where feasible to reduce branch costs (function-constants are a Metal feature that allow efficient runtime recompilation of bytecode shaders).
- Buffer<> & RWBuffer<> types where the STRONG_TYPE macro is added as a type-qualifier (only does something on Metal, everywhere else it is #define'd away) are compiled as "raw" Metal buffers of the inner-type (e.g. float4 for Buffer<float4>) and the MetalRHI runtime will enforce that only SRVs/UAVs of the proper format are bound to it. This is necessary in a couple of cases (BoneMatrices, NumCulledLightsGrid, CulledLightDataGrid & ForwardLocalLightBuffer buffers) which are used in a larger number of shaders as Linear Textures have poorer performance than Buffer<>/RWBuffer<>.
- Most of the complications to generating subtly different Metal code for different OS/device combinations have been factored out into ue4_stdlib.metal which acts as an extension to the Metal shader standard-library and helps simplify the MetalBackend code - particularly helpful for Buffer<>/RWBuffer<> but also texturecube_array and the SM6 wave-related intrinsics.
- Reverted some of the awkward Metal-specific changes Richard.Wallis & Arne had to make to the high-level shaders as they aren't necessary anymore.
- Made the existing Metal-specific changes to use uint32 for all light-grid injection buffers apply to all Metal platforms again (I had hoped that it would not be necessary anymore, but it is much faster this way).
- STRONG_TYPE is actually hlslcc's "invariant" keyword applied as a type-qualifier to a Buffer<>/RWBuffer<> type - only valid when using Metal which exports this through ILanguageSpec and #define'd out for everyone else.
- Old versions of iOS (anything earlier than iOS 10.3) won't be able to use this new code, so every buffer will be treated as "raw" and the MetalRHI will now properly report when something goes awry rather than it leading to mysterious rendering errors and crashes.
Change 3710456 by Mark.Satterthwaite
Fix the Eddie workset project generator so that Enterprise projects don't get mixed in with regular projects at the top-level because of the way Eddie combines workset groups.
Change 3710457 by Mark.Satterthwaite

MSVC type-mismatch error fixes.
Change 3710580 by Mark.Satterthwaite
Alright then - if I can't use the C++11 extended string semantics I'll have to use "xxd -i" to generate a hex-dump include header from ue4_stdlib.metal instead. This can only be updated from a machine with access to the POSIX xxd command (Mac & Linux, possibly the new Linux sub-system for Win10).
Change 3710616 by Mark.Satterthwaite
Missing file.
Change 3712972 by Guillaume.Abadie
Fixes Circle DOF's negative alpha channel getting clamped to 0 in TAA pass.
Change 3712979 by Guillaume.Abadie
Fixes wrong RT reallocation when doing TAA upsample in editor viewports with secondary upscale.
Change 3713406 by Mark.Satterthwaite
Use GPU morph targets on Mac - the necessary buffer conversions will always be available there. For iOS it can only be supported if iOS 10 is the minimum OS & Metal standard so leave that on the CPU path for now.
Change 3713494 by Richard.Wallis
Fix for hitch when PIE unloading sublevel. PerformReachabilityAnalysisOnObjects is spawing multiple threads in Editor builds as there is an extra code path that results in Critical Section locking within a singleton type static object - this is a bottle neck for multiple threads. However they all just need to read the data not change it. Replaced FScopeLock with a Read/Write version allowing these threads to all take a read lock at the same time to reduce contention.
Changed the FUObjectAnnotationDense implementation only - left the sparse implementation alone as its not currently affecting this - although we could proactivly change that too.
Also tested again repro in linked bug UE-24711.

Integrate LPV_STORE_INDEX_IN_HEAD_BUFFER related changes from //depot/Partners/Microsoft/UE4-MS/Engine-Fable @ 2954744
This should make Light Propagation Volumes potentially viable on non-Microsoft platforms.
Change 3713623 by Mark.Satterthwaite
Implement ByteAddressBuffer/RWByteAddressBuffer in hlslcc in a similar manner to StructuredBuffer/RWStructuredBuffer so that the backends don't need too much modification. Implement the necessary changes into MetalBackend to make this work for Metal.
Load/Store{+2,3,4} & Atomics are supported. Counter operations are not supported and aren't likely to be.
Change 3713636 by Mark.Satterthwaite
Enable LPVs for Mac Metal.
- Rework some multi-dimensional arrays & array-index dependent HLSL code that hlslcc simply can't cope with, the mesa-glsl compiler core is only capable of dealing with 1 dimensional arrays and array-indexing can't itself be directly dependent on the result of an array-index operation.
- MetalRHI needs to ignore any SetRenderTargets call that binds nothing at all as you must bind at least one target (UAV, RT, Depth/Stencil) for it to be able to do anything sensible.
- Turn on LPVs for Metal as it works now.
Change 3714049 by Guillaume.Abadie
Do not set screen percentage method to TAA upsample when anti aliasing method is not TAA even if there is automatic fallback in the renderer.

Rewrites editor primitive compositing to support TAA upsample.
This takes the oportunity to remove the manual depth testing in base pass pixel shader of editor primitives.
Change 3716271 by Daniel.Wright
Lightmass correctness fixes
* After these changes, point, spot, directional and sky lights closely match reference renderer Mitsuba after light unit conversions
* Photon density trimming intended for direct photons was affecting indirect photons as well. This caused high noise for point / spot lights with a large attenuation radius. Indirect photon density even for small lights is 5x with this change, which improves 2nd bounce quality.
* Removed legacy fudge factor on point / spot light photon energy
* Spotlights no longer emit based on indirect photon paths. Fixes excessive photon energy from spot lights as they were emitting outside of the cone.
* Fixed photons computing one more bounce than requested.
* Added an option to use the Radiosity solver for all multibounce, replacing photons. Useful as a reference but generally too much noise indoors.
* Fixed visualization of photons without final gather
Change 3716434 by Mark.Satterthwaite

Also implemanted batching of the dispatches which should help worst case perfomance where dispatches become too small.
CalculateInverseAccumulatedWeights is not cheap and proably should be moved onto a task thread that runs as soon as the input weights are ready.
Change 3717127 by Mark.Satterthwaite

Change 3718589 by Mark.Satterthwaite
Console-variable to enable and disable Manual-Vertex-Fetch for Metal and fix the internal code to handle the subtle changes in behaviour for vertex-declarations so we don't explode under the Metal validation layer. MVF works on macOS, though testing did expose an error with Tessellation on Nvidia (true for MVF enabled & disabled).

Change 3720099 by Mark.Satterthwaite
Make the left-hand arguments work in airdiff.
Change 3720413 by Mark.Satterthwaite
Support standalone compute shaders in the mtlpp compiler test app.
Change 3721232 by Mark.Satterthwaite
No more Metal Shader Model 4 - instead we have to have a Metal Shader Model 5 w/o Tessellation as Nvidia's shader compiler is broken on all tessellation shaders in 10.13.0 and above. There is no guarantee that they will fix this prior to 10.14 and I can't afford to disable tessellation entirely as if I do that then the AMD & Intel compilers will also regress. As there is no Shader Model 4 platform on Mac anymore I've amended the LevelEditorActions to disable the preview modes when no appropriate shader platform is available.

Change 3722943 by Mark.Satterthwaite
Disable the METAL_SM5_NOTESS shader platform again - I can workaround the Nvidia pipeline state compiler crash by changing the buffer address space from "constant" to "device" as we're managing to confuse the poor thing. This won't materially affect AMD or Intel as they don't care much about this, but to limit performance issues on Nvidia we only need to do this for Tessellation Compute shaders.
Change 3723100 by Mark.Satterthwaite
Apparently users like enabling Metal shader standards that won't work on their current OS, so don't display those that aren't going to work & display an error message before quitting rather than crashing when trying to load a project that tries to use an incompatible shader version.

Render thread dynamic resolution & TAA upsample.
Merging //Tasks/UE4/Dev-DynamicRes/...@3694528 to //UE4/Dev-Rendering/...
New features breakdown:
- TAA upsample compute shader that accepts screen percentage from 50% to 200%, with a faster shader permutation for consoles;
- Material no longer have to deal with BufferUV, and post process material after TAA upsample can sample any scene buffer seamlessly;
- Material texture per view mip bias to produce sharper images with TAA upsample;
- Render thread dynamic resolution heuristic is fully plugable by game code (for VR plugin specific heuristics);
- Dynamic resolution in PIE and game builds;
- Busy time queries in the RHI to be implemented on the different platforms so that the dynamic resolution heuristic can exactly associate GPU frame times with screen percentages in its history;
- Game user settings to enable/disable dynamic resolution;
- In editor viewport screen percentage config to previsualise and test content at different screen percentage.
Fixes:
- Various fixes for algorithms producing different outputs at different screen percentage.
- Various fixes for algorithms sampling outside view rects.
Refactors:
- TAA shader
- Moved some screen percentage specific members from FSceneView to FViewInfo for thread race bullet proofing.
Aknowledgements:
- VR plugins are broken
- DFAO still have some artifacts

Change 3441680 by Uriel.Doyon
Added units to point light intensity, to allow the user to specify the value in candelas or lumens.
New point light actors now configure the intensity in candelas by default.
Replaced viewport exposure settings by an EV100 slider.
Hidding the tone mapper in the show flag now still applies the exposure.
Added a new AutoExposure method called EV100 which allows to specify :
- MinEV100, MaxEV100

Visualize volumetric lightmaps uses 18% grey in lit mode
Change 3636398 by Daniel.Wright
Translucency lighting modes work with Volumetric Lightmaps
* The old Indirect Lighting Cache always interpolated one sample per object, while Volumetric lightmaps operate at the frequency of the Translucency Lighting Mode (per-vertex or per-pixel) so the lighting accuracy is much higher.
* The old ILC always applied the single lighting sample with a per-pixel normal, even in per-vertex lighting modes
* Volumetric PerVertex NonDirectional (cheapest lit translucency) went from 74 instructions down to 42
* Volumetric Directional went from 104 up to 122
Change 3636604 by Chris.Bunner
Added a material translation error on identically named/associated but differently valued parameters as this will cause one of them to be lost during parameter evaluation, the result being "random".

Change 3640053 by Mark.Satterthwaite
Fix Desktop Forward rendering on Nvidia Metal rendering on macOS by modifying the shader and runtime to treat ForwardLocalLightBuffer data as uint rather than float and invert the use of as*() casts.
Tthis is *necessary* to avoid a bug/limitation of Nvidia's current Metal shader compiler that flushes all denorm values to zero on load from any resource. AMD & iOS Metal only flush-to-zero when sampling from textures and that's what Apple regard as the expected behaviour. I have however asked them to standardise on the D3D behaviour of preserving denorms on all load, move (incl. min/max/as*()-casts) & store operations. This won't happen in the current or imminent OS/Xcode releases.
Now only Intel Metal is broken and their problems run deeper.
#jira UE-48881

Change 3642442 by Mark.Satterthwaite
Fix the native shader libraries again & undo the increase in cook time from changes to the way FShaderCodeLibrary was compiling & deduplicating the shaders.
- Remvoe the single linear array for accumulated shader code: reallocating this is tremendously expensive and will double the time taken to iteratively cook large projects.
- Uncompress the shader data for the native library system so that it actually works again.
- Fix some errant change to the Metal compiler that was trying to wedge the fully compiled library into the single Metal library which is 100% bogus.

Ref-count the mtlpp Device object so that it can be the repository for IMP caching - now just have to go through the types created from a specific device and have them keep a reference....
Change 3644431 by Uriel.Doyon
Added a intensity units property, for point lights and spot lights, that can be set to Candelas, Lumens or Unitless (legacy).
The default units value for newly placed point lights and spot lights is configured in the project settings.
Spot lights configured in lumens have their whole luminous energy redirected toward the cone.
This means that changing the outer cone angle, changes the spot light brightness.
New exposure menu that uses an EV100 slider.
New post process settings "camera" tab regrouping : ShutterSpeed, ISO, Aperture and ExposureCompensation.
Post process settings "auto exposure" tab renamed "exposure".
The calibration constant for "Auto Exposure Basic" is now configurable in the advanced tab.
The auto exposure method is renamed "Metering Mode"
New pre-exposure feature that allows the engine to apply the previous frame exposure before writing to the scene color.
This allows the engine to render the scene with similar range than the final color (after exposure), and avoid arithmetic overflow for low precision RT formats.
The amount of exposure applied directly is called pre-exposure, and is compensated by a smaller post-exposure value.

Change 3650436 by Mark.Satterthwaite
Implemented the necessary extensions for Metal shading language to move lots of complexity out of MetalBackend and into actual shader code to make life *vastly* simpler.
- Full ue4::typed_buffer<T> wrapper type & associated ue4::buffer<>/ue4::buffer_atomic<> API - totally untested but should be functionally equivalent to HLSL Buffer<T>/RWBuffer<T>.
- All the sensible casts I can think of are now defined in ue4_format - any additional ones can just be added. The enurm of formats needs to be exposed to MetalRHI so we upload the correct values, but this should be trivial.
- Added a full series of wrappers around texturecube_array and depthcube_array to insulate code from whether it is backed by a real cube_array or a texture2d_array so we don't have to maintain complicated variants for new/old iOS devices.
- Added implementations for a bunch of annoying HLSL & GLSL intrinsics that were being matched by name + reverse_bits which needs a custom implementation on old shader standards.

D3D11 equivalent to 3656341 (only enabled when -d3ddebug is) to validate DrawIndexedPrimitives isn't trying to draw off the end of the instanced vertex streams which has inconsistent (and potentially undefined) behaviour across the various APIs we support. This fires when painting the landscape because the code attempts to render with a FirstInstance value that is as large as the number of elements in the instance-data streams which D3D11 drivers silently fails to render, but which Metal (& probably Vulkan too) will renders as garbage. This pattern is wrong & will be even more dangerous in a Draw*Indirect world.

* Sky lights which capture the scene now work correctly with Lighting Scenarios
* Lighting Scenarios must now be loaded for each time they are made visible (no switching back and forth while keeping both loaded)

Initial, incomplete, tool added to mtlpp to help debug macOS Internal Compiler Errors - the mtlpp command-line tool can be fed the debug output from UE4 along with compiler settings to automatically compile shaders and construct the render pipeline that crashes the runtime compiler.

In the prototype Metal stdlib extension library add inline versions of the D3D SM6 "wave" intrinsics that can be expressed in terms of Metal 2.0 simd/quad group operations (macOS=simd, iOS=quad). These are unlikely to be as efficient as direct intrinsics but they should be functionally equivalent.
These functions are not available *yet* as I still need to hook the ue4_stdlib into MetalShaderFormat & MetalRHI.
The following HLSL 6 functions are implemented:
WaveAllBitAnd
WaveAllMax
WaveAllMin
WaveAllBitOr
WaveAllBitXor
WaveAllEqual
WaveAllProduct
WaveAllSum
WaveAllTrue
WaveAnyTrue
WaveBallot
WaveGetLaneCount

3667805 Changing sincos in Metal fragment shaders had undesirable side-effects - the compiler is now re-associating another floating point operation - so limit the use of precise::sincos to vertex-shaders for now. This fixes the WPO materials without causing any other obvious problems.

Change 3669912 by Mark.Satterthwaite
Fix Metal compilation for PCSS shadows - the HLSL that is compiled uses both SampleCmp and Sample which GLSL disallows (shadowSampler types in GLSL only allow SampleCmp) but is perfectly valid in Metal where only the texture type declaration changes.

Change 3670989 by Mark.Satterthwaite
Stop trying to be so clever with Metal clip-distances: AMD have a bug in 10.13.0 that means we can only emit one clip-distance value, so simply emit the value with the lowest index (we have handily ordered them by importance!) and let the others become user-interpolators until this bug is resolved in a macOS SU (according to Max@AMD the fix is in, just not in time for 4.18). This means planar reflections will work, VR no-multi-view-fallback will work & layered rendering will work either individually or together - the difference being that on macOS *only* the VR no-multi-view-fallback & layered rendering paths may be slower when combined with the global clip plane.
Hit & run fix to MetalCaptureManager and availability of tile-shader functions while I'm here.

Submitted on behalf of Richard Wallis:
Only disable V-Sync on Metal in macOS 10.13 when running in "true" fullscreen mode (where we switch display modes & forbid switching spaces or tabbing out) so that you won't see the rainbow artefact caused by being out-of-sync with WindowServer, only the tearing you'd expect when V-Sync is disabled. We'll chat with Apple about whether there is a way to avoid the rainbow artefact when switching spaces in Windowed Fullscreen with displaySync disabled.

Enabling WorldPositionOffset requires disabling fast-math on Metal because the manually specified FMA's are not respected if one or more arguments is a literal which then leads to very different compiler optimisation between the depth-only shader and the base-pass shader.

Lightmass skylight solver improvements
* Lightmass uses a filtered cubemap to represent the skylight instead of a 3rd order Spherical Harmonic. Directionality in shadowed areas is improved. Mip level is chosen based on the ray differential for anti-aliasing.
* Multiple skylight and emissive bounces are now supported with a radiosity solver, controlled by NumSkyLightingBounces in Lightmass WorldSettings. More bounces results in longer build times, and the radiosity time is not distributable.
* The mapping surface cache is now rasterized with supersampling, reduces incorrect darkness in corners
* Combined direct lighting, photon irradiance, skylight radiosity and diffuse in the mapping surface cache so final gather rays only have to do one memory fetch, speeds up lighting builds by 7%.
* Added support for Embree packet tracing although no solver algorithms use it yet
Change 3618413 by Daniel.Wright
Swarm hands out the most expensive tasks in roughly a round robin ordering among distribution agents. Lightmass processing of a single task is multithreaded, so ideally the most expensive tasks are evenly distributed among active agents. This has the biggest impact in small scenes with 10's of high resolution lightmaps, and with a distribution farm. Build time in one scene went from to 113s -> 47s.

Fix cloth rendering on Metal - some of the data in FClothVertex is uint but we load it from a float buffer. This could be due to a bug in Metal's as_type<uint4>() or it could be that Xcode 9's compiler is now finally enforcing Metal's official flush-to-zero-on-load semantics for denorms - it isn't immediately obvious.

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 3093470 on 2016/08/18 by Ben.Woodhouse
Fix minor leak in FMonitoredProcess - the Thread member would get leaked if the FMonitoredProcess was cancelled, because it gets NULLed without deleting it. Fix is to add a bool to keep track of whether the thread is running, rather than using the Thread pointer.
Also fixes a race condition where the FMonitoredProcess::Thread member could get initialized after the thread had completed. This would cause IsRunning to never return false, even if the thread has completed, and the editor would hang on startup (this was fixed by setting bIsRunning to true before creating the thread)

Fully featured base pass reflection captures with blending and parallax correction
* Used in the forward renderer when materials opt-in to 'High Quality Reflections'
* Used in the deferred renderer for translucent 'Surface ForwardShading' materials
* Reflection captures are culled to a frustum space grid using the same reverse linked-list method as lights in the forward renderer
* Fixed grid culling in stereo / splitscreen
* The ReflectionEnvironment compute shader used in the deferred path also uses the culled grid now which reduces its cost from .93ms -> .70ms on 970 GTX. PS4 cost is about the same.
* Capsule indirect self-shadowing is now reduced in the forward path to match deferred, and both are controlled by r.CapsuleIndirectShadowSelfShadowIntensity
* SetupHZB is now skipped when SSAO / SSR / HZB are all disabled

Fixed various issues with subsurface profile, for checkerboard and non-checkerboard code paths
- Re-enable non-checkerboard skin by default
- Checkerboard issues fixed:
- Emissive lighting was being applied twice due to not taking checkerboard pattern into account
- Emissive lighting was modulated by basecolor in the recombine
- Metallic materials were contributing specular lighting to the diffuse channel
- Non-checkerboard fixes:
- Fix write mask during SkyLightDiffuse so alpha is updated correctly
- Metallic specular lighting was broken (specularColor was lerping to white instead of baseColor)
- Optimisation: Fall back to default lit for pixels where the opacity is 0.
- For non-checkerboard, this gives better handling of metallic/emissive for pixels where SSS is not required (non-CB RGBA encoding for diffuse/spec doesn't cope well with colored specular or emissive)
- For checkerboard, this gives similar results in terms of shading, but we get full-resolution shading on non SSS pixels

The cause was that FD3D11BoundRenderTargets doesn't support setting RTs sparsely. So if one element is NULL, it won't release the ones after it.
The sparse RT layout happened as a result of a change back in October, which meant that GBuffers for decals could be set sparsely, dependent on whether the decal wrote to the normalbuffer
This change adds support for sparsely bound rendertargets in FD3D11BoundRenderTargets.

Forward renderer initial implementation
* Point and spot lights are culled to a frustum space grid, base pass loops over culled lights.
* Light culling uses a reverse linked list to avoid a per-cell limit, and the linked list is compacted to an array before the base pass.
* New cvars to control light culling: r.Forward.MaxCulledLightsPerCell, r.Forward.LightGridSizeZ, r.Forward.LightGridPixelSize
* A full Z Prepass is forced with forward shading. This allows deferred rendering before the base pass of shadow projection methods that only rely on depth.
* Dynamic shadows are packed based on the assigned stationary light ShadowMapChannel, since stationary lights are already restricted to 4 overlapping.
* GBuffer render targets are still allocated
* Fixed several issues in parallax corrected base pass reflections - not blending out box shape, discontinuity in reflection vector, not blending with stationary skylight properly
* Forward shading is now used for TLM_SurfacePerPixelLighting translucency in the deferred path
* Notable missing features: shadowing of translucency, support for various translucency lighting modes, multiple blended reflection captures

Shadow depth refactor
* Shadow setup and render target allocation now happens in InitViews, and shadow depth rendering happens at one spot in the frame
* This provides control over where shadow depths are rendered for things like async compute, and allows easy atlasing of shadowmaps for forward shading
* The 33Mb of shadow depth buffers in FSceneRenderTargets has been removed, and shadow depth buffers are now allocated as needed
* A large amount of duplicated code to handle each shadow type has been combined
* Cleaner parallel rendering: no more view hacking for the shadow depth pass, no more shadow depths in the middle of translucency
* 'vis ShadowDepthAtlas' or 'vis WholeSceneShadowMap' must now be used to visualize the shadow depth textures

Cached shadowmaps for whole scene point and spot light shadows
* Controlled by 'r.Shadow.CacheWholeSceneShadows', defaults to enabled (7ms -> 1.5ms of shadow depths on Titan for ~20 lights)
* Primitives with Static or Stationary mobility have their depths cached, as long as the light is not moving
* Primitives with Movable mobility or using World Position Offset in their materials will not have their depths cached
* Cached shadowmaps are copied each frame and then movable primitive depths composited
* Fast paths exist for when there were no static primitives (skip cached shadowmap) or movable primitives (project directly from cached shadowmap)
* 'r.Shadow.CacheWPOPrimitives' controls whether materials using WPO can be cached (default is off for correctness)
* 'r.Shadow.CachedShadowsCastFromMovablePrimitives' can be used to force off all support for movable primitives, skipping the shadowmap copies (1.5ms -> 0ms of shadow depths for ~20 lights)

Add a per-object shadow setting for directional lights (r.Shadow.PerObjectDirectionalDepthBias), which is independent of the CSM setting. Often a smaller bias is desirable on per-object shadows, where detailed self-shadowing is needed.
This change also makes the CSM naming consistent with what the setting actually does (the old setting was named r.shadow.csm, although it affects per-object shadows as well as CSMs).

Change 2963214 on 2016/05/02 by Ben.Marsh
BuildGraph: Allow specifying optional dependencies for a node, indicating that the build products from an upstream node are desired, but should not block the node from running.
Change 2972295 on 2016/05/10 by Ben.Marsh
EC: Remove spacing in notification emails to reduce size, and help prevent gmail from truncating messages. Also allow mailing notification emails when doing a dry run, and reading stream settings from another branch.

Change 2733540 on 2015/10/19 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream
Capsule shadows
* Capsule shadows excel at extremely soft area shadows caused by a large light source angle, but don't support accurate self-shadowing
* Artists can setup a physics asset containing Spheres and Sphyls (capsules) for a skeletal mesh that will be used to represent the mesh's occlusion
* These shapes can then be used for direct shadowing (bCastCapsuleDirectShadow) on a skeletal mesh component, whose softness depends on the light source angle / radius
* The shapes can also be used to create an indirect shadow (bCastCapsuleIndirectShadow), whose direction and softness is derived from the precomputed sky occlusion (stationary sky light) or primary indirect lighting (static sky light)
* Capsule shadowing is computed at half res and uses tiled deferred culling for efficiency - only implemented for PC SM5 + PS4 so far
* Shadowing of movable skylights is not yet supported
Change 2735460 on 2015/10/20 by Uriel.Doyon@uriel.doyon_office_data
Basepass drawlist are now merged within a single drawlist.

RHIIsRenderingSuspended
Change 2745714 on 2015/10/28 by Daniel.Wright@Daniel.Wright_G5038_RenderingStream
Lighting channels - each component and light can choose from 3 channels
* Primitives output their channel mask to stencil during the base pass, the masks are copied to a texture after the base pass, deferred lighting passes compare the primitive mask against the light's mask
* Dynamic shadow casting also respects the channels
* Only works on opaque materials, direct lighting, dynamic lighting
* Not implemented for tiled deferred atm
* This will replace CastsShadowsFromCinematicObjectsOnly in the future

Lightmass solver quality improvements
* IndirectLightingScale is no longer applied to photons, avoids splotchy artifacts when using small scales
* New 'Lightmass Portal' actor / component which tells the solver where to look for significant lighting. When lighting with a Static Skylight only, in a mostly indoor environment, setting up these portals is the only way to get high quality.
* Skylight bounce lighting is now much more accurate and leverages adaptive sampling
* Fixed a bug that effectively disabled adaptive sampling on high IndirectLightingQualities
* Shadow penumbras are also improved by IndirectLightingQuality
* Texel debugging is now a cvar 'r.TexelDebugging', instead of requiring a full recompile
