Fix for BI_BITFIELDS: The color masks are at the same position in all 

the bitmap headers that support this flag (BITMAPINFO: The first color
mask is in bmiColors[0], that's the same position as bV4RedMask in
BITMAPV4HEADER).

If biCompression is BI_BITFIELDS, the color masks are at the same position
in all the headers (they start at bmiColors of BITMAPINFOHEADER), because
the new headers have structure members for the masks.
