--- Comment #9 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The only guidance I see regarding what can be in the bitfields is from
https://docs.microsoft.com/en-us/windows/win32/api/wingdi/ns-wingdi-bitmapv5header

"""
When the bV5Compression member is BI_BITFIELDS, bits set in each DWORD mask
must be contiguous and should not overlap the bits of another mask. All the
bits in the pixel do not need to be used.
"""

So it probably has to handle arbitrary(ish) masks. The patch from Dmitry also
does in-place fixups to the data -- is that acceptable? Without knowing more, I
would have assumed that the data comes from the application or is otherwise
read-only.
