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.

Some P4V problem with backing out large changelist missed some files.

Rob asked me to back out GENERATED_*_BODY -> GENERATED_BODY change for now until the "_Validate and _Implementation auto-generation" discussion is over.

Override Material Editor specific Static Mesh Component bounds calculation to use Aggregate Geometry Box Sphere bounds function.
Calculate tighter bounds for Aggregate Geometry that only contains a sphere.
[CL 2367471 by Matthew Griffin in Main branch]
- Improved UI. Removed bOverrideBaseProperties as it was pointless. Altered customization to place check boxes for overrides next to their values like the parameters of instances.
- Overrides now respect the parent chain.
- Mirrored the override data in the MIC render proxy.

#ttp 339373 - Crash: when you create a endless loop with material instance that has it self as a parent the editor will become unresponsive
#branch UE4
#proj Editor.MaterialEditor, Editor.UnrealEd, Runtime.Engine
[CL 2320455 by Richard TalbotWatkin in Main branch]
Invalid/useless "EditInline" tags removed. UHT generates error when "EditInline" is used for property other than Object reference (or an array).

#TTP 340962 - LIVE: RENDERING: Font Sample Parameter Behavior in MIC
Created sub struct for UDEditorFontParameterValue to contain the font parameter fields.
Removed font specific widget construction as it can now use the generic CreateParameterValueWidget function to build the UI.
