I tried using dat2s/fixup_datafile instead of load_datafile in your test
program, and the error really showed up. The last 2 lines in the patch are
related to this. Maybe I should try to come up with something which looks a
bit nicer and uses bitmap_mask_color()? (The docs don't even mention that any
flags have an effect on fixup_datafile, but ignoring it seems wrong..)

Besides this, I fixed the un-needed drawing_mode now, and the 2nd case level
for 15bit.

I also tested RLE_SPRITES, luckily control and databytes are never mixed there
so no problems with any conversions. They work even when data-bytes get the
same value as the EOL marker.

So after this patch, it should be possible to load any bitmap data into any
colordepth, and transparency would be preserved when the KEEP_TRANS flag is
set.
