[Chromium-dev] Patch for windows

[<dr...@bf...>]

Please find attached a patch with some fixes for the OpenGL stub on windows:

1. The functions wglGetCurrentContext() and wglGetCurrentDC() return 
NULL in the current implementation. I changed them to return the proper 
GL context and device context respectively.

2. In wglChoosePixelFormat() okayFlags should include 
PFD_GENERIC_FORMAT. The flag basically says that there is no hardware 
acceleration at all [1], [2].
