The docs for -drawInRect: say it does nothing if you haven't set the size of
the image. I know the size is (potentially) different from the
pixel-width/height, although I don't know if NSBitmapImageRep assumes an
initial size based on the pixel dimensions.
Also, you probably don't want to draw to the dirty rect. You want to draw to
the view's bounds, presumably.
