Yes, morphic should make it all very easy, but doesn't do the trick
quite yet. I did an alternate drawing canvas a while ago for
generating Postscript, and it turned out that the device independence
really wasn't there yet, with much drawing logic actually residing
in specialized morphs that blit their results to the FormCanvas.
Fortunately, Andreas is working on an overhaul that should fix this
(see Dan's list of 2.5 updates). I hope this will enable me to
finally finish this piece of work that has been idling ever since I
got the message that Squeak Central was going to address this.
Anyway, I was able to actually use a slightly modified version of
the Postscrtip canvas for interactive drawing on a DPS-based system,
so it should be possible to generalize this code to output to just
about any sufficently powerful high-level graphics API/format ( X,
VNC, GDI, QuickDraw, PDF, ...).
