I don't think you want to do that for biBitCount > 8.

I'm not near the source code now but AFAIR DecompressQuery would refuse such bitmap because it does not support biClrUsed > 0 when bit count > 8. But I will clarify that in a third version, certainly it would be a waste of memory to allocate memory unnecessarely.
