would take work.  Nice BTW - that's the only HW I know of on pc that
does unlimited subwindows...  (though it can be faked using BITBLT'd
textures afaik :)

Yep.  AFAIK all the S3 PCI cards can.  S3 -likes- being able to support
non-intel hardware.

It's a global flag, not a buffer-local one though - so -all- buffers would
be either big-endian or little-endian.

G'day, eh? :)
