[first, a general comment. Adding features like this are the *perfect*
opportunity for people to subclass Swarm library objects. Some people
out there are doing this now for their own work. I regret that I
haven't had time to look at what's been done, to see if there are new
generally useful classes and/or whether new features should be added
in to the existing classes.]

Could you change the draw code so that before it draws a mosquito
("skeeter", in Texas terminology) it first does the transform, then
checks for a collision, then doesn't draw the mosquito if it collides
with the hut?

This would be something like a specialized hut-and-mosquito drawing
class. Not such a bad idea, really, and it fits in with some of my
newest code that has an object that does nothing but draw agents on
Raster widgets.
