You can either keep track of the location of all your bitmaps, and then 
write a HitTest function that is able to translate mouse events on your 
canvas to the bitmap that they occurred on, and then send an event with 
the info you need.  Or you can use something like OGL or FloatCanvas 
that already does this for you.
