  Renamed from patch 0013.
-0004-Make-it-possible-to-link-ANGLE-statically-for-single
  Removed. Fixed by adding defines to project files.
-0008-ANGLE-Dynamically-load-D3D-compiler-from-a-list-or-t
  Renamed to patch 0005.
-0009-ANGLE-Support-WinRT
  Removed. Mostly fixed upstream; remaining parts in patch 0001.
