[pygame] hq3x magnification algorithm

[Eric Burgess <eric@big-brain.org>]

"hq3x" is the name of a very cool algorithm for enlarging low-color 
(cartoonish) low-resolution images.

I think it would be pretty nifty to implement this in pygame...but I 
really know nothing at all about linking C or ASM code with Python.  
Does anyone have an opinion (educated or otherwise) on how difficult it 
would be to integrate these two?
