As the mipmaps levels aren't being generated on level 9, they shouldn't
be used. Fall back to multisampled textures instead (which is the
behavior for non-power-of-two textures anyway). This fixes an issue in
which textured polygons (e.g. QML Images) turn black when scaled down.

Some level 9 hardware does not support 32-bit indices, and in most
places this is already checked. It would appear that most phone
hardware actually does support 32-bit indices, and so this bug wasn't
caught until testing on the Surface RT. This is not surprising, as some
level 9 resources are only a minimum for the hardware spec, not the
true limit of the device/driver.
This patch provides the general fix to use 16-bit indices on such
hardware, but a whitelist of known good GPUs should be added to enable
32-bit indices where available.

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.
