I wouldn't have thought sub-screens was relevant, but I guess that makes
sense, if by "sub-screen" you can mean a portion of a virtual screen/bitmap
stored in memory. Thanks for the clue.

Yeah, I figure bitmap.e has a bm_rotate() function, but the problem is you
have to feed it a 2-d sequence, and I don't know how to retrieve the 2-d
graphic sequence stored by neil.

The "rle_handle" is an atom, as far as I can tell... right?

I guess since his "blur.ex" runs on my home PC fine, then I should be able
to use rle_sprites... I'll investigate further.

Thanks!!
