Do you need to exactly replicate the TkCanvas interface in the zoomable 
canvas? Why not get creative and develop a class with a new (possibly 
better) interface? (And maybe use delegation rather than inheritance.) 
The TkCanvas interface is close to Tcl/Tk's canvas, which is great for 
documentation and porting, but it's not necessarily very ruby-like.
