Reducing pygame cpu-load to < 4 %

[Noah Kantrowitz]

Unfortunately this is not possible in most games, as doing them purely
vector-based is infeasible. A lot of the artwork made for games will be
standard raster graphics, and will need to be designed for a specific
screen. If there are changes in the future, they can always be redrawn.
