+0001-ANGLE-Improve-Windows-Phone-support
  Consolidated remaining parts from 0009/0010.
+0002-ANGLE-Fix-compilation-with-MinGW
  Remaining issues from patch 0016.
+0003-ANGLE-Fix-compilation-with-MSVC2010
  Remaining issues from patch 0015.
+0004-ANGLE-Dynamically-load-D3D-compiler-from-list
  Renamed from patch 0008.
+0005-ANGLE-Add-support-for-querying-platform-device
  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.
-0010-ANGLE-Enable-D3D11-for-feature-level-9-cards
  Removed. Mostly fixed upstream; remaining parts in patch 0001.
-0012-ANGLE-fix-semantic-index-lookup
  Removed. Fixed upstream.
-0013-ANGLE-Add-support-for-querying-platform-device
  Renamed to patch 0005.
-0014-Let-ANGLE-use-multithreaded-devices-if-necessary
  Removed. No longer needed.
-0015-ANGLE-Fix-angle-d3d11-on-MSVC2010
  Moved remaining parts to patch 0003.
-0016-ANGLE-Fix-compilation-with-MinGW-D3D11
  Moved remaining parts to patch 0002.
