[PATCH 0/1] MR8710: opengl32: Perform cAccumBits filtering if specified in wglChoosePixelFormat().

[JiangYi Chen (＠meshine)]

On Windows, if wglChoosePixelFormat specifies cAccumBits, the best matching
PIXELFORMATDESCRIPTOR obtained should contain AccumBits information.
Some industrial software, such as CAD applications, require matching
the AccumBits information.
