How is that handled in HTML's Canvas?  Is the SVG Canvas any different?

I don't want to talk you out of adding the stack viewer object if that's 
easier to do (that's the one thing I miss from Gain Momenum), but given 
how HTML5 and SVG allow different scales for different objects I'd favor 
any solution that reduces learning time for folks familiar with those 
popular solutions.
