According to the specs wglChoosePixelFormatARB returns the number of matching 
pixelformats. This number can be different than the size of the return buffer 
which is given by nFormats.

Unfortunately glXChooseFBConfig doesn't return all formats when NULL is passed 
for the attributes. This is due to some default settings not being 0 
or 'Don't care'. This required changes to ConvertAttribWGLtoGLX.
