The collision detection is basically the same as isPointInPath(), already 
in HTML5, and the locking is implicit in most <canvas> implementations (it 
only repaints in between script executions, and this is actually called 
out in HTML5 as the right thing to do), so I don't think there's anything 
to add from 2dgame at this point.
