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 2860430 on 2016/02/09 by Aaron.McLeran
UE-26216 EQ Settings are incorrect, unable to produce a LPF setting
- Fix is to expose the xaudio2 eq effect parameters actually used
- Added support for real-time previewing of EQ parameter changes (interpolates from current to new values)
Platform code:
- CoreAudio's EQ AU effects have identical settings as well, translated the params to the mac code
- PS4 code was disabled before -- this change is a first-pass implementation for PS4, but its still not enabled
Change 2867932 on 2016/02/15 by Aaron.McLeran
Some adjustments and cleanups to recent dev-framework features
- Removing change to ObjectVersion in favor of a TaggedPropertyRedirect in BaseEngine.ini for EQSettings variables
- Adding bIsTraceDelegateBound bool for flagging need to add delegate binding for async traces
- Reverse iteratoing through PendingSoundsToDelete for deferred delete for async occlusion checks and using RemoveAtAtSwap

Change 2897815 on 2016/03/07 by Zak.Middleton
#ue4 - Avoid multiple iterations with axis flipping in FindTeleportSpot unless we are spawning something. Otherwise the teleport spot could be placed on the other side of a wall. Also avoid using a partial MTD result in EncroachingBlockingGeometry() when one of the MTD tests fails.
#rb Jeff.Farris, Matt.Oelfke
Change 2897819 on 2016/03/07 by Zak.Middleton
#ue4 - FInterpTo() now treats negative values as instant speed as well as zero, consistent with other *InterpTo() functions. Previously it only treated zero as instant, and negative speeds returned the "Current" value.

Don't dirty level when launching standalone from editor
Rework spawning temporary spawn here player start when launching standalone from editor to use a transaction and undo it rather than spawn and destroy
Add a mechanism to squelch notification messages
Add the ability for a undo to say that the transaction cannot be undone

Changed AllocateNameEntry to be template based instead of branching off of whether the string is ansi or wide in multiple places
Removed the load time hashing of FNameEntry as they are loaded which improves FLinkerLoad::SerializeNameMap() perf

Change 2775736 on 2015/11/20 by Richard.Hinckley
Fix for Paper2D issue with repeated imports in one edutor session. Paper2D import process now creates a new importer at the end. This prevents the sprite sheet import process from leaving frame data around, causing subsequent imports (including imports of different sprite sheets) to include this data inappropriately.

Implemented a way to do batched points projection to navmesh, where every point can declare a custom projection box #UE4
The biggest advantage here is that projection box is independent from projected point - no more manual offsetting of projected point to achieve "100uu up and 500uu down"-like functionality

Gameplay debugging tools fixes #UE4
Fixes:
- made newly added logs respect Log Visualizer's filters
- added handling of invalid data when trying to draw EGameplayDebuggerShapeElement::Cylinder in AGameplayDebuggingHUDComponent::DrawPerception. This is a patch, root cause to be found.
- fixed Log Visualizer resetting it's data while trying to serialize invalid objects. This is a patch, root cause to be addressed.
In addition
- while at it removed bunch of 'auto' and 'class' keywords from the files I've touched

Moving occlusion feature settings from audio component to sound attenuation settings struct.
- Sound attenuation setting struct is used for all sounds that do 3d spatialization so it make sense for the occlusion feature settings to be there.
- Kept old low-pass frequency filter setting values on audio component (where HighFrequencyAttenuation used to be)

#ue4 - FMath::Atan2() no longer calls atan2f() because of some compiler or library bugs causing it to randomly return NaN for valid input. It now uses a high-precision minimax approximation instead, measured to be 2x faster than the stock C version.
