FImage is now the standard preferred type for a bag of pixels
FImageView can point at pixels without owning an allocation
ERawImageFormat (FImage) converts to ETextureSourceFormat
FImageUtils provides generic load/save and get/set from FImage
major cleanup in the ImageWrappers
new preferred API is through ImageWrapperModule Compress/Decompress
SetRaw/GetRaw functions cleaned up to not have undefined behavior on unexpected formats
ImageWrapper output added for HDR,BMP,TGA
RGBA32F format added and supported throughout import/export
EditorFactories import/export made more generic, most image types handled the same way using FImage now
Deprecate old TSF RGBA order pixel formats
Fix many crashes or bad handling of unusual pixel formats
Pixel access functions should be used instead of switches on pixel type

MAJOR FEATURES + CHANGES

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.

Fixing a problem with widget components crashing on destruction with the render commands to pre/post render for window render commands needing access to the policy, but it potentially being deleted. Inserting a NoOp command that keeps the shared ptr alive through the RHI render process.
#jira UE-25752
Change 2836342 on 2016/01/20 by Nick.Darnell
Depending on shutdown order, the Slate Renderer may go away, and then render data handles may not be collected correctly because they are trying to reference a pointer that's no longer valid and cause a crash on exit. The correct approach would be to have render handles actually have a pointer back to who owns them, in this case the RHI Resource Manager, which is still alive and well at this point in the pipeline. Then if the resource manager is collected, it forces all handles to get cleaned up correctly, or if the handles are collected first, they can be sure they've got a valid pointer back to the resource manager.

Change 2836782 on 2016/01/20 by Jamie.Dale
Added FTextLayout::AddLines
This is similar to AddLine, however it allows you to add multiple lines in a single call, thus avoiding the re-justification cost associated with each call to AddLine.
AddLine has also been changed to take the same structure type as AddLines (which takes an array of these structures), and the existing version of AddLine has been deprecated.
