SV: [pygame] Fullscreen perfomance problems

["John Eriksson" <john@xxxxxxxxxxxx>]

Ok, some progress.

This gives poor perfomance:
FULLSCREEN|DOUBLEBUF|HWSURFACE

This gives poor perfomance:
FULLSCREEN|DOUBLEBUF

This gives poor perfomance and some bad flickering:
FULLSCREEN|HWSURFACE

This gives perfect result:
FULLSCREEN

What do you think about this?
