Autogenerated with:
cp dom/.clang-format gfx/ && mach format gfx/**.{cpp,h,mm}
Manual changes:
* OSVRSession headers are not system headers and they are not
standalone / rely on stdint, so tweaked to preserve previous
ordering.
* Missing include in GLDefs.h
* Missing include in gfxOTSUtils.
* Need to keep the windows header order in DCLayerTree.
* missing hb_font include in MockScaledFont.h
