clean up a slight jitter when drawing circles
Earlier the ghost while drawing wouldn't quite match the final shape.
Now the math is identical in draw_pending_shape.

It's a little unfortunate that we have this duplication of formulae.

At least there are no other stray calls of App.mouse_x in
draw_pending_shape.
