[pygame] I nedd speed

["Gabriele Farina" <mrfaro@libero.it>]

Hi guys,

I'm working on a GUI engine writte using Pygame. I'm at a good point, I
finished all the widgets I need, but I have to know how can I impreve my
script speed. I'd like to know some tricks for speeding up my GUI, in
paticular i'd like to know how can I update only a single part of a surface.

Other 2 things:
1) Using sprites makes the script work slower or not??
2) How does surfaces-lock work??When (and why) I have to use it??

tnx a lot, good night
