I've pretty well got this solved, but the animation has a problem.
As the horses move, they erase the "start line", and it stays erased after they've passed.
Also, they leave a trail. I suspect it's the leftmost few pixels from the previous drawing (the rear hoofs).
How can I restore the start line after the horses have passed it, and how can I fully erase the horse before drawing it in it's new position.
I suspect it has something to do with "Invalidate()", but I can't get it to work.
