all the drawing stuff is fairly new to pygame. for the most part they 
work, but as we can see, they're not quite 100% yet. i'll try to find 
out why we see that line on the edge.

as for the lockup, it happens for me too, so it should be a bit easier 
to debug. i'm not sure what this is. i think it's also related to the 
drawing functions, since i've never seen anything else do it.

also, for your info. python's garbage collector is different from java. 
it doesn't hang on to objects and then free them all in a big garbage 
collection sweep. python objects are freed as soon as they are 
unreferenced. so in python there's no hangs or freezes like that for 
garbage collection. :]

this is correct. the Surface objects are builtin python types. if this 
is really a problem for you, it is all being fixed in python-2.2 (due 
decemeber, but beta is out now). python-2.2 "fixes" the differences 
between python classes and python types.

for the most part though, this hasn't been a problem in any game 
development. most designs use "has-a" surface, instead of "is-a" surface.


still, sucks to see those bugs with the polygon drawing. for now all i 
can recommend is "don't do it like that". i'll try to figure out exactly 
why it happens.
