AW: [AD] Paletted Bitmap Grabber PlugIn & Allegro Extension

[Jörg Rüppel <sharky-x@xxxxxxxxxx>]

Ok, I see your point. I tried to implement it as grabber-plugin-only without
altering allegro.h. I put the PAL_BITMAP struct into the OBS code and
everything is fine. BUT: The grabber now knows how to grab and save this
file. But when I load an already stored DATAFILE which contains such an
object, the grabber doesn't know how to handle this and treats it as binary!
I also could simply import my paletted bitmaps as BIN objets and read them
in the game, but then I can't view them in the grabber. In order to let the
grabber load it correctly, I need to either modify allegro in the core
sources, or I need a way to register some proper loading routines to the dat
utility, which is not possible, if I haven't missed anything. Any solutions?
What advantages brings the plugin-system to me, when I am not able to write
proper plugins without altering Allegro in it's base?
