Upgrade ANGLE to 1.3.5bb7ec572d0a
This brings Qt's copy of ANGLE up to ANGLE master, which contains a number of bugfixes as well as restructuring for the upcoming ES 3.0 support. This version brings considerable stability improvements to the D3D11 renderer. The static translator project files have been merged to align with the ANGLE source tree. Two new patches have been applied to fix errors in upstream ANGLE: - 0011-ANGLE-Fix-compilation-error-on-MinGW-caused-by-trace.patch The event trace header in ANGLE's third_party directory has an unused template which causes a compilation error on MinGW. Disable this part of the code. - 0012-ANGLE-fix-semantic-index-lookup.patch The sorted semantic index table was returning a direct mapping to the new indices, instead of the old indices. This caused a mismatch in the GL type lookup for the translated attribute. All other patches have been rebased, removed if no longer needed, and renamed to clear up the application order: - 0001-Fix-compilation-for-MSVC-2008-and-std-tuple.patch No changes. - 0001-Fix-compilation-with-MinGW-mingw-tdm64-gcc-4.8.1.patch No changes. Renamed to 0002. - 0001-Fix-compilation-with-MinGW-gcc-64-bit.patch No changes. Renamed to 0003. - 0001-Make-it-possible-to-link-ANGLE-statically-for-single.patch Modified patch to adapt to new DLL loading structure. Renamed to 0004. - 0005-Fix-build-when-SSE2-is-not-available.patch No changes. - 0011-Fix-compilation-of-libGLESv2-with-older-MinGW-w64-he.patch No changes. Renamed to 0006. - 0006-Make-DX9-DX11-mutually-exclusive.patch Made the patch less invasive by allowing D3D9 code to run unless explicitly disabled (e.g. on WinRT, where it doesn't compile). This makes the patch smaller and allows Desktop Windows to compile both D3D9 and D3D11 codepaths. Renamed to 0007. - 0015-ANGLE-Dynamically-load-D3D-compiler-from-a-list-of-k.patch No changes. Renamed to 0008. - 0012-ANGLE-Support-WinRT.patch Made D3D11_level9 initialization only possible if D3D9 is disabled. This makes sure Desktop PCs use the old D3D9 codepath instead of the less-tested D3D11_level9 codepath. Renamed to 0009. - 0013-Enable-D3D11-for-feature-level-9-cards.patch Conveniently smaller patch due to buffer implementation improvements upstream. Renamed to 0010. - 0014-ANGLE-D3D11-Alwayls-execute-QueryInterface.patch This was a fix for patch 0009, so was integrated there. Removed. - 0016-ANGLE-D3D11-Fix-build-on-desktop-Windows.patch This was a fix for patch 0009, so it was integrated there. Removed. - 0001-ANGLE-Fix-compilation-with-MSVC2013.patch Fixed upstream. Removed. - 0007-ANGLE-Fix-typedefs-for-Win64.patch Fixed upstream. Removed. - 0004-Fix-black-screen-after-minimizing-OpenGL-window-with.patch The issue has been fixed in Qt itself. Removed. - 0008-DX11-Prevent-assert-when-view-is-minimized-or-.patch The cause of the problem was the same as patch 0004, but for the D3D11 codepath. Removed.
