I didn't think it needed explanation. Ofcourse it's faster to draw
less, and the fastest way is obviously to not draw anything at all,
but that's not a very useful approach...
The whole point of having a virtual area is so you can draw onto it!
Haven't you ever used a virtual window manager under X?
And besides you have no idea about what parts of the virtual area will
be visible.
If you want to optimize drawing, use the clipping area.
