MAJOR FEATURES + CHANGES
==========================
Change 2719147 on 2015/10/07 by Mark.Satterthwaite
Allow the shader cache to perform some precompilation synchronously on load before falling back to asynchronous compilation to balance load times against total time spent precompiling. Added a stat to the group that reports how long the precompile has been running until it completes so it is easier to track.
Change 2719182 on 2015/10/07 by Mark.Satterthwaite
Refactor the ShaderCache's internal data structures and change the way we handle recording whether a particular predraw state has been submitted to try and make it more efficient.
Change 2719185 on 2015/10/07 by Mark.Satterthwaite
Merging CL #2717701: Try and fix random crashes on Mac when manipulating bound-shader-states caused by ShaderCache potentially providing a bogus shader state pointer on exit from predraw.
Change 2719434 on 2015/10/07 by Mark.Satterthwaite
Make sure that Mac ensures reports have a source context and a sane callstack when sent to the crash-reports server.
Change 2724764 on 2015/10/12 by Josh.Adams
[Initial AppleTV support]
Merging //depot/YakBranch/... to //UE4/Dev-Platform/...
Change 2726266 on 2015/10/13 by Lee.Clark
PS4 - Calc reserve size required for DMA copy when using unsafe command buffers
Change 2726401 on 2015/10/13 by Mark.Satterthwaite
Merging CL #2716418: Fix UE-15228 'Crash Report Client doesn't restart into project editor on Mac' by reporting the original command line supplied by LaunchMac, not the modified one that strips the project name. The CRC can then relaunch as expected.

Change 2726421 on 2015/10/13 by Lee.Clark
PS4 - Don't try to clear invalid targets
Change 2727040 on 2015/10/13 by Michael.Trepka
Merging CL 2724777 - Fixed splash screen rendering for images with DPI different than 72
Change 2729783 on 2015/10/15 by Keith.Judge
Fix huge memory leak in Test/Shipping configurations, caused because I am a numpty.
Change 2729847 on 2015/10/15 by Mark.Satterthwaite
Merging CL #2729846: On OS X unconstrain windows from the dimension of the parent display when in Windowed mode - it is OK for them to be larger in this case. They do need to be repositioned if on the Primary display so that they don't creep under the menu bar and become unmovable/unclosable and Fullscreen windows still need to be constrained to a single display. We can now take screenshots of windows that are larger than the display & not get grey bars beyond the cutoff.
#jira UE-21992
Change 2729865 on 2015/10/15 by Keith.Judge
Fast semantics - Finish up resource transitions, adding resource decompression where appropriate and using non-fast clears where we can't determine the resource transition.
Change 2729897 on 2015/10/15 by Keith.Judge
Fast Semantics - Make sure all GetData() calls are made safe with GPU fences.
Change 2729972 on 2015/10/15 by Keith.Judge
Removed the last vestiges of ID3D11DeviceContext/ID3D11DeviceContext1 from the Xbox RHI. Everything now uses ID3D11DeviceContextX directly.
This should be marginally quicker as it stops a double call to ClearState().
Change 2731503 on 2015/10/16 by Keith.Judge
Added _XDK_VERSION to the DDC key for textures, which should solve the issue of the tiling mode changing in August XDK (and future changes Microsoft may inflict).
Change 2731596 on 2015/10/16 by Keith.Judge
Fast Semantics - Add deferred resource deletion queue to make deleted resources be actually deleted a number of frames later so that the GPU is definitely finished with them. Hooked up the temporary SRVs for dynamic VBs as a first step.

Change 2732018 on 2015/10/16 by Mark.Satterthwaite
Emit a shader code cache for each platforms requested shader formats, this is separate to the targeted formats as not all can or need to be cached.
- The implementation extends the ShaderCache's hooks in FShaderResource's serialisation function to capture the required shaders.
- Each target platform has its own list of cached shader formats, analogous to the list of targeted RHIs. Presently only the Mac implements this.
- Code cached shaders are now compressed (for size) to reduce the overhead associated with keeping all the shader code around - this works esp. well for text-based formats like GLSL.
Change 2732365 on 2015/10/16 by Josh.Adams
- Packaging a TVOS .ipa now works (still haven't tried any of the Editor integration like Launch On)
Change 2733170 on 2015/10/18 by Terence.Burns
Fix for Android IAP query not returning entire inventory.
Change 2733174 on 2015/10/18 by Terence.Burns
Fix Movie player issue where wait for movie to finish isnt being respected.
Seems a stray bUserCanceled event flag was causing this not to be observed.
Added some verbose logging to apple movie player.
Change 2733488 on 2015/10/19 by Mark.Satterthwaite
Added the ability to merge the .ushadercache files used by the ShaderCache to store shader & draw state information.
- Fixed a bug that would cause invalid shader membership and draw state information to be logged.
- Added a separate command-line tool to merge shader cache files, currently Mac-only but in theory should work on other platforms too.
Change 2735226 on 2015/10/20 by Mark.Satterthwaite
Fix temporal AA rendering on GL/Mac OS X - you can't rely on EyeAdaptation values unless SM5 is available so only perform that code on SM5 & we must correctly clamp saturate(NaN) to 0 as the current hlslcc won't do that for us (& is required by the HLSL spec). The latter used to be clamped in the AA_ALPHA && AA_VELOCITY_WEIGHTING code block that was removed recently.

Change 2736722 on 2015/10/21 by Daniel.Lamb
Improved performance of cooking stats system.
Change 2737172 on 2015/10/21 by Daniel.Lamb
Improved cooking stats performance for ddc stats.
Adding Texture LOD settings to Device Profiles
- this will improve how we currently edit and override lod settings on a per device type bases.
- LOD Settings can now be set in the Device Profile Editor
- Any device profiles with no values set for LOD Settings, will use the default objects.
- These can be found in BaseDeviceProfiles.ini in the /Script/Engine.TextureLODSettings section
- Appropriate defaults set for those groups not listed.
-Other fixes
- - Incorrect with_editor check in HTML5 target platform, changed to with_engine
[CL 2481510 by Terence Burns in Main branch]
- Moved HighQualityLightmap support check to IOSTargetPlatform so it can check project settings for Metal support
- Fixed some issues running on an x86_64 device
- Cleaned up some unused functions in TargetPlatform

[CL 2478853 by Josh Adams in Main branch]
We already had FPlatformProcess::CreateProc/CloseProc pair (which is part of larger set with WaitForProc(), TerminateProc(), GetProcReturnCode(), etc). FProcHandle::Close() made the API more confusing (and actually introduced bugs, because it did not call CloseProc() until recently).

[CL 2476322 by Dmitry Rekman in Main branch]
- Added class to hold values (AndroidSDKSettings)
- Added code to Android editor module to setup the values on load
- Changed device detection so that the thread is always started and the SDK path can be changed on the fly
- Changed Platform Target Management Module so that a single platform can be checked via UBT
- Settings can now be sourced from an ini file via temp direct reading code (auto seralisation is disabled until later changes are made)
-- Settings currently not exposed in editor
- Added Mac Environment var setting support
Unreleated
- Envars can now be passed down to process start points in tools

[CL 2412194 by Robert Jones in Main branch]
* Multicast delegate Add* calls now return FDelegateHandles, and Remove* calls are now all deprecated, except for a new Remove function which takes a FDelegateHandle.
* New FConsoleManager::RegisterConsoleVariableSink_Handle and UnregisterConsoleVariableSink_Handle functions which work in terms of FConsoleVariableSinkHandle.
* Timer calls which don't take FTimerHandles are deprecated.
* FTicker::AddTicker now returns an FDelegateHandle and is removed by an overloaded Remove function.
* DEFINE_ONLINE_DELEGATE* macros now define _Handle variants of the Add/Remove functions which return/take handles.
* Various other handle-based registration changes.
* Some unity build fixes.
* Some simplification of delegate code.
* Fixes for lots of existing code to use handle-based registration and unregistration.

[CL 2400883 by Steve Robb in Main branch]
- Enabled ES31 for GitHub/P4 users (currently only works on a Tegra K1 with recent system software)
- Always use separate APKs - this means that all APKs will have -armv7-es2 (or whatever) in their name. This may affect scripts, etc people have written
- Fixed a bug when using multiple java libraries (for users who add their own libs)
- Properly collapse Android devices into a single device with multiple variants. LaunchOn will now choose the best format based on the connected device. If you want to override the format, you will need to use the ProjectLauncher
- Added Android serial number to the device type, in case you have multiple devices of the same type (also fixes [UE-3770])
