[pygame] Dumb little question: Crossfade

[Bill Coderre <bcbc@xxxxxxx>]

I want to cross-fade between two images.

I imagine this is like 3 lines of code. Can someone send me a sample?

I tried reading the docs on the pygame website, and I see there's a  
bunch of flags on surfaces that are not explained. I imagine it has  
something to do with them.

Thanks!
