I've got a program that uses server gl canvases, and redrawing them for each
expose event is rather slow. What is the best way to avoid re-rendering the
canvases? Should I draw into a pixmap and make it the background pixmap? Is
there some double buffering thing I can use?
Also, is there any way to use data from different gl canvases together?
I'd like to add two canvases up in the accumulation buffer, but it seems
like each canvas is totally seperate as far as gl is concerned.
