I'm unsure where the problem lies, but with wxAutoBufferedPaint the 
drawing is really double buffered --> no flicker on zoom. There has to be 
a very serious problem if one can get 80% Xorg and 30% PCBnew CPU usage on 
C2D just by rolling zoom on an empty board (grid dots on). My gut feeling 
is immediate drawing mode and not using wxGC. Isn't wxDC going to get 
phased out soon too?

Current R2221 doesn't solve stuff, but BCBnew crashes on zoom...
