Antialias painting is slow, but this is not the reason why this program 
is unusable even on a powerful computer.

The reason is that mouse move events are never ignored. If your mouse 
cursor moves 20 pixels in one direction (for example) between two 
occurences of the event loop, you will receive 20 MouseMove events, not 
one. And so the rendering will be done 20 times for nothing.

The solution is to add a timer to the form, and instead of calling 
"graph_draw" at each mouse move event, you trigger the timer instead, 
and it's the timer event handler that will call "graph_draw". That way, 
the rendering will be done once by event loop, and not once for each 
mouse move events.

Another bug in the application: don't mix the cube if you have partially 
move one of its face. All faces will display incorrectly.
