[pygame] working with "blobs"

["Kurt Yoder" <ktypygame@xxxxxxxxxxxxx>]

Hi all,

I've been creating "blobs" in a cartesian grid system manually up until
now, but I wonder if there is an easier way to do it? Does pygame include
a method of merging geometric objects, finding their inside/outside,
finding the half-way point between opposite sides, etc? If not pygame,
perhaps some other python library?

Thanks,

-Kurt
