Two demos: SCEE demo 'offscr', and the game 'Between The Eyes'
(available from my homepage, ~lewis_e).

Both use DrawProcesses, which are just structures for holding data
about the off-screen drawing; the crucial things are to change
GsDRAWENV.clip and .ofs;
the .clip RECT should be set to where you draw offscreen
(eg in your case, 760, 256, w, h)
and the ofs should be set to the top-left corner of that area (ie 760, 256)

Off-screen drawing very useful for dynamic textures, mirroring, and other
nice things

I need to know how to draw off of the regular screen.  I've looked at
the SCEE demo on the subject, but I could only figure out a little bit
of it.
Every frame, I want to draw to 760x256.  So, I use PutDrawEnv to change
the DRAWENV variable.  The only thing I don't understand is the ofs
property of the DRAWENV.  If I want to draw to the same space every
time, should these just be zero?
