Success and a new problem

Oops. I just sent this to just Dmitry, so I'm resending it to the list. (Sorry,
Dmitry, that you're getting this twice.)

I found the problem: I was calling repaint in my VScroll_Change. Since I was already calling
scroll when I set the offset, this was completely unnecessary. Now the flicker is gone.
Thanks. (I fixed on_paint anyway, just on general principles.)

My new problem is that my program doesn't catch mousewheel events. I tried an
on_mousewheel sub that does nothing but report that it was caught (print "mousewheel $x,
$y, $z\n"), but it's not catching them. Is there something special I have to do? I've looked in
TextView (because podview.pl does respond to mousewheel events on my machine), but I
can't find where it's doing anything special.
