It has the same purpose as 'offbits' in
BmpFrameDecode_ReadUncompressed() from bmpdecode.c. And in bfOffBits,
too. Please give me a hint, I still think it is clear this way.

:D Okay, that proves your point. This is a short from for 'offbits ?
offbits : size'. Will fix that.

Hmm, do you have a pointer for a test verifying how something should
look like (in contrast to checking a return value)? Was this not
necessary for LoadImage() in general?
