[PD-dev] how to use canvas_getcurrent() ?

[Miller Puckette]

Hmm, this is already done, sort of, by the symbol binding mechanism.  Perhaps
I should go binding the current canvas to sa symbol and just return _that_.
But I'm scared of the potential performance hit of having everything
have to work that way.
