Hi Ken,

This is the kind of stuff I'd like to make possible in Morphic 3. There 
could be various views (Displays) on the same World or subworlds of it. 
We need to come up with a design that makes this easy.

Right now, the #drawOn: message doesn't need a scale, because the 
coordinate transformation from the Morph's to Display's is built into 
the Canvas. Please take a look at ivars transformations, 
currentTransformation, and cti in FormCanvas. (This was the hardest part 
of making each morph have its own coordinate system, as it is right now 
in Cuis, even if scaling doesn't work properly yet).

Maybe a good solution would be to have different Canvases for each display.

Cheers,
