[OLPC-Games] Pygame

[Bert Freudenberg]

Yes, they explain the Anti-aliasing quite nicely.

It would be way cool if someone would hack Zephyr to scale the  
display. We have this for Squeak/Etoys and it allows you to develop  
using a 1200x900 frame buffer in a window with a physical size that  
matches the XO. Immensely useful.
