chackie, this one has got me. i just tried passing no arguments, and it 
'clears' the clipping rectangle just fine for me. this hasn't changed 
for a long time, so it should be working for you (i'd expect any pygame 
version above 1.0)

mysurface.set_clip()  #this should do it and work for you

in SDL, there is always a clipping rectangle. when it isn't set it's set 
to the full size of the surface. so no, there's no performance penalty 
for having it set to the full surface.

in cvs i just updated the function to also accept "None" to clear the 
clipping, but that's nothing you should need to get it working. i also 
fixed the docs :]
