   Here's a REALLY cheap way of detecting clicks on irregular shapes: draw the
   shapes in different colours, so you can sample the pixel clicked on to 
   figure out which shape was picked.

Except that (1) this forces you to click exactly on the shape boundary
for an unfilled shape and (2) it forces every shape to be a different
color.  Useful for some applications, not for others.
