This is precisely the problem with Canvas.  In SVG, you do have the 
geometric shapes as DOM objects instead, and you can let the renderer do any 
calculations required to modify the shape; the only thing you have to tell 
it is which shape you want.  Also, there is no standard that you can even 
remotely rely on, while SVG is a Web standard.  I regard Canvas as a 
technique inferior to SVG.
