: So it's not just a matter of changing some little bit of data which specifies

: the texture collection data, it automatically clears all textures from
: surfaces (what does? how?), so you'd have to (make the program) go back

Well, I could tell you how *I'd* do it, but that's less than useful... for the record, collection specified per-level; bitmap assignments and alignments per-surface.
