I'm trying to create multiple rastports that write on the same bitmap.
I also want each rastport to think of the upper left corner of the part
of the bitmap that it can write into as 0,0 (i.e., I'd like the system
to do translation for me).  I looked around in the RKM (vol 1) and
couldn't see how to do it.  Could someone point me to the right
section, or give me a code fragment?

BTW, I'm using this to write into a window, if that makes it easier (or
harder).  I assume I can just grab the bitmap from the window and build
a few rastport and rasinfo structures to do this, but can't figure out
how.

Thanks in advance.

(PS:  I tried to send this to comp.sys.amiga.tech, but we don't get it,
so I can't post there.  I hope technical discussions continue to be
crossposted at least until the situation gets clarified.)
