I've got a pointer to a dib now. I wanted to look at that code to see how it
"registers" the dib to get a win32lib handle or whatever, but the only thing with
freeimage I can find in the archive is freedib, which includes freeimage.ew, but
that doesn't contain CreateHBitmap() or fiCreateHBitmap().
However, it contains fiCreateFIBitmap() and fiCreateDIB(). I've got no clue what
either of them do, and there are no docs covering them.
