Hi,

What should I do in order to be able to draw in the APP process?
The pfChannel man pages say "... only the draw process is attached
to a graphics context." How (if possible) to make APP share this
graphics context and the window DRAW creates? The aim is to be
able to draw from APP with no switching overhead.

I know two processes cannot draw to the same window at the same time,
but suppose I can do exclusion properly...

Any suggestions appreciated! Thanks,

Hansong
