I guess what confuses me is that I thought J (or the OS, or someone) did this 
for me, already. I mean, I already told J (or the OS,
or someone) what I want painted, and that's obviously what I also want 
repainted whenever required, until I change my mind (at which
time I'll inform someone).    My picture must be in memory somewhere, right?  
What if it takes a lot of time, or lines of code, etc,
to draw?

Given that J is single-threaded, is there ever a time a J programmer would need 
to implement a paint event handler, assuming he
already painted his picture once, and didn't intend to change it?
