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.

* You should never access the color table using the bmiColors member,
