Callable shaders are similar to hit shaders, but they can be invoked from RayGen shaders without tracing any rays. They have records in the shader binding table and allow local parameters to be bound. The total number of callable shader slots/records must be declared when creating a ray tracing scene. Each record must be filled using SetRayTracingCallableShader() command, which is similar to SetRayTracingHitGroup().

This implements the framework to write the high level rendering code into passes organized in direct acyclic graph. It is also unifying the uniform buffer, shader parameters, and pass parameters to same single API: structures with run time meta data. This allow high level user code be extremely seamless, user code debugging, and render graph ease of implementation and debugging.
Issue of collaborative work of Arne Schnober, Brian Karis, Daniel Wright, Marcus Wassmer and Guillaume Abadie.
Names of the graph managed resources are not final.

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.

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).

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 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).

UE-49173 Progress bar causes black screen on iOS
#iOS
#4.20
#jira UE-49173
The bug occurs on iOS with Metal, when the last Slate element to be draw in the scene is a ScrollBar with progress between 0 and 1.
As a workaround, adding another widget (eg. button, image) in the Blueprint solves the problem.
The bug can be reproduced by adding OutDrawElements.PushClip & OutDrawElements.PopClip in any SWidget::OnPaint.
The solution is to disable the scissor
RHICmdList.SetScissorRect(false, 0, 0, 0, 0);
in FSlateRHIRenderingPolicy::DrawElements after the batch rendering

#jira UE-54490
Call ForceCompletion for the intial movie player on onPause.
Call App Restart on Resume.
Programmatically restarting an Android application basically consists in killing the current app, then using the launch intent as parameter for startActivity.
This can be done only in onResume , which means that the movie player still has to be manually paused/stopped in onPause.
I╞ve tried to kill the activity on onPause, tested on several devices, with various problems: the app doesn╞t restart anymore (onResume is not called) or the app is automatically sent to background (seems to be crashing when using the multitasking soft key).

Most of the times there is a desync and the data is not yet loaded when the lightmap is validated (in FScene::AddPrecomputedVolumetricLightmap).

Note: Using a new AutomationTool command (re-starting the Automation tool after canceling the BuildCookRun task chain) is too slow - takes 3-10 sec depending on the PC configuration.
AutomationTool is used now only to correctly retrieve the bundle id for each Android device. This is done inside the BuildCookRun command when the application is deployed on the device(s). Cannot simply use the current project's properties to retrieve the bundle id, because when using Launch-> Device Launcher, the user can choose to cook&deploy a different project/texture format, also the user can create & use a profile with multiple devices / with different texture formats.

UEMOB-436 Support "All Android" Launch On and Project Launcher options
The main change is in the DeviceProxy class.
A new type ("All devices" proxy) was added, and the proxy now holds a list of physical device IDs for every variant (texture format), instead of a single device ID.
The "All devices" proxy is updated automatically by the device discovery thread.
The change was necessary because the list in the Project Launcher is using the device proxy list.
