The complexity of the scalars isn't much an issue, more the quantity of 
elements is what brings tcl/tk down. I think the problem is there, and 
not really with the Pd core.

Zoom is also easy with donecanvasdialog or coords messages, although the 
speed doesn't change.

It also makes it faster and less prone to bugs to close the canvas while 
the scalars are being redone, then open it. Vis messages automatize that 
with no issues.
