I haven't added this, because for the kind of retained-mode graphics that 
this implies, SVG is a much better fit.

However, <canvas> does now have isPointInPath() which allows one to get 
somewhat the same effect. When we add separate Path objects in the future, 
this will even allow hit testing to be done just by walking through a 
series of objects instead of recreating each shape for each hit test.
