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 3094167 on 2016/08/18 by Jeff.Fisher
UEVR-97 Morpheus HMD tracking needs to wait until HMD is fully tracked.
-Morpheus CALIBRATING/NOT_TRACKED tracking state hmd orientation update disabled and delegates added to present instructions to the user. This behavior is controlled by morpheus ini setting bDisableHMDOrientationUntilHMDHasBeenTracked, but defaulted to true to avoid subtly bad user experiences.

UEVR-178 Morpheus HMD Black crescents
-Switched reprojection frame time for 60/120 mode from 120hz to 60hz so we much better predict where the hmd will be pointing when the frame we are about to render is actually displayed, and are run off the edge of it less often and less severely. This makes the black crescent artifacts only just visible during very fast head turning. The kWrapModeMirror change, which will be submitted separately, makes the left and right crescents invisible to me.
-Renamed the functions for setting the prediction info in the PS4Tracker.
-Added render frame parameters to sony reprojection functions, these can help with debugging reprojection.
-Added commented out sce call to get the reprojection debug data. Not allowed to submit an executable that calls it, but its nice to at least know where one can put it. May improve this later.
-Wrapped PS4Tracker->Synchronize call in a check that the tracker handle is valid, because I managed to get it called when it wasn't (probably during hmd power off testing, but I don't remember now). It should be fine to not do it if the tracker is not functioning.

Morpheus Config Improvements.
-UEVR-138 Morpheus HMD reprojection wrap mode config setting
-Can now switch between wrap mode Mirror and ClampToBorder. Mirror is the default.
-Made bDisableHMDOrientationUntilHMDHasBeenTracked editable in UE4Editor project settings.
-Using generic project setting for bStartInVR, removed the morpheus specific one.

Change 3111231 on 2016/09/01 by Jeff.Fisher
Fixed bStartInVR ini setting.
-Initial implementation worked via a generic EnableStereo call, which worked, but happened after the hmd setup dialog, which is not what I wanted.
-Also fixed a tracking frame mismatch assert that hit when I powered the hmd off once, causing it to lose tracking. Its ok that it doesn't update in that circumstance.

UEVR-126 Morpheus HMD connect dialog cancel reactions
-VR only apps can't allow the player to cancel out of the hmd setup dialog, so lets just pop the dialog up again (sony were ok with a licencee doing this) if an ini setting says to do that.
-VR/2D apps might want to switch to 2d if the player cancels out of the hmd setup dialog, so there is an ini setting for that.
-A delegate only implementation is also provided for apps that want to do something else. This leaves the game rendering in VR mode, and fires the delegate.
-Refactored to better separate successful HMD acquisition from stereo rendering. This was necessary to support the delegate only option on startup. If you start in vr mode with your hmd off and cancel the dialog stereo rendering now starts with default values for the hmd hardware stats (as read from my pvt) instead of crashing trying to use uninitialized data. When an hmd is connected its values will be read.
-Refactored to ensure reprojection starts immediately when we call StartReprojection.

UEVR-135 Morpheus HMD recent feature error reporting
UEVR-173 2DVR flexibility (UTexture)
-Error log for sceHmdReprojectionSetOutputMinColor failure.

* Else, call SetScreenPercentage using the current value
The obsolete HMD SCREENPERCENTAGE console command is still available and will override the setting until r.ScreenPercentage is modified the next time.

PS4 Stereo Layer double buffering. Since the overlays are reprojected at 120hz but rendered at 60hz we need to render to a separate buffer than the one being used by reprojection.

UEVR-225 Morpheus HMD top and bottom black crescents

Don't depend on the current state of the VR subsystem when exiting PIE mode to decide whether the main window should be restored. Instead always restore it if it was minimized at the start.
Change 3136652 on 2016/09/22 by Keli.Hlodversson
Allow shutting down Steam VR subsystem without shutting down the Steam VR plugin completely in response to quitting from the SteamVR overlay. Enabling stereo rendering again will reinitialize SteamVR. This is useful when using PIE in VR mode as it allows entereing it again without restarting the editor. Also fixes crashes by first disabinge stereo rendering a short while before shutting down the VR subsystem.

UEVR-242 Is AddControllerYawInput not allowed when morpheus is enabled?
-Indeed it did not work. Looks like morpheus would not accumulate the yaw, so it would be reset every frame. I made the implementation of ApplyHmdRotation very similar to the one used for occulus (also similar to other platforms) to fix this.

UEVR-14 PSVR Support for 90Hz to 90Hz, and 120Hz to 120Hz
-Enum setting added for the three frame sequences.
-90Hz mode is trying to run camera updates at 90hz, but they can only run at 60 so every third one fails. This works, but its dubious.
-Feature marked as experimental for now because of that 90hz tracking issue, and the lack of testing.
-Defaulting to 60/120.

Change 3081374 on 2016/08/08 by Ben.Marsh
UBT: Invalidate the makefile if any UHT headers are deleted. Should fix issue where files are moved from one module to another, and the original module no longer contains any generated headers. Its include path needs to be removed from the compile environment.

Change 3087457 on 2016/08/12 by Ben.Marsh
Core: Reorganize the FTransform and FMatrix headers: Transform.h now includes TransformNonVectorized.h or TransformVectorized.h as appropriate, and UnrealMatrix.h is now Matrix.inl (and included from Matrix.h).
Change 3088407 on 2016/08/13 by Ben.Marsh
Replace use of Windows SIZE_T define with the regular C++ size_t.
Change 3088416 on 2016/08/13 by Ben.Marsh
Include a header from all .generated.cpp files (GeneratedCppIncludes.h) which includes all the basic types required to compile them, rather than assuming that the module PCH will include everything.
Also include the real declarations of noexport classes in Object.h (now renamed to NoExportTypes.h for clarity) when the CPP macro is defined, so the .generated.deps.h file will automatically have the correct definitions for them at compile time rather than relying on them being in the private PCH.
Finally, rename UObject.h to Object.h for consistency with the naming convention for all other UObject classes. UObject.h still exists for now, but outputs a deprecated message if included.
Change 3088544 on 2016/08/14 by Ben.Marsh
Core: Move the definition of the TEXT() macro into Platform.h, to avoid having to include OS headers to get it.
Change 3088552 on 2016/08/14 by Ben.Marsh
