I am trying to do double buffering using Quickdraw without much success.
I can write into different windows using SetPort and I can sometimes
swap windows using SelectWindow, but I can`t get it to do either very
cleanly at the update rates I need (~30 fps).  Any suggestions, code, or
help would be greatly appreciated.
