Haskell is fast enough and wxWindows itself, too. I think that calling
wxWindows from Haskell takes a little time, though. And that adds up if you
try to draw hundreds of pixels. I believe there is a faster way by drawing
pixels to a buffer and then displaying that buffer. Anyway, drawing the
rectangles works fine, I think.
