Removed. All changes are now handled elsewhere.
+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.
