Re: [pygame] pygame.transform.scale and anti-aliasing

Hello

Thanks a lot for the hints! I made a try with pygame.image.rotzoom  
and the quality is really much better! The outline (anti-aliasing)  
will be removed more the smaller you zoom in but its still much  
better than the scale functions. I didnt test the performance yet but  
rotzoom doesn't seem to be much slower.

Thanks!!!!
