ANGLE: upgrade to 2.1~07d49ef5350a
This version of ANGLE provides partial ES3 support, numerous bug fixes, and several potentially useful vendor extensions. All patches have been rebased. The following changes are noted: 0000-General-fixes-for-ANGLE-2.1.patch contains compile fixes for the new ANGLE 0004-Make-it-possible-to-link-ANGLE-statically-for-single.patch has incorporated patch 0015. 0007-Make-DX9-DX11-mutually-exclusive.patch has been removed as it was fixed upstream. 0007-Fix-ANGLE-build-with-Microsoft-Visual-Studio-14-CTP.patch has been moved up to fill the patch number gap. 0010-ANGLE-Enable-D3D11-for-feature-level-9-cards.patch now contains patch 0014 and 0017. 0013-ANGLE-Allow-for-universal-program-binaries.patch has been removed as it is no longer relevant. 0014-ANGLE-D3D11-Fix-internal-index-buffer-for-level-9-ha.patch has been merged with patch 0010. 0015-ANGLE-Don-t-export-DLLMain-functions-for-static-buil.patch has been merged with patch 0004. 0016-ANGLE-WinRT-Call-Trim-when-application-suspends.patch has been removed and will be replaced by a follow-up patch using a different technique. 0017-ANGLE-D3D11-Don-t-use-mipmaps-in-level-9-textures.patch has been merged with patch 0010. 0018-ANGLE-WinRT-Create-swap-chain-using-physical-resolut.patch has been removed and will be replaced by a follow-up patch extending the EGL_ANGLE_window_fixed_size extension. 0019-Fix-ANGLE-build-with-Microsoft-Visual-Studio-14-CTP.patch is now patch 0007. [ChangeLog][Third-party libraries] ANGLE has been upgraded to version 2.1, bringing partial support for OpenGL ES3 over Direct3D 11, numerous bug fixes, and several new vendor extensions.
