This is nothing new, Pd uses Tcl/Tk inefficiently (for example,  
creating and destroying graphics instead of using the tk "move"  
command).  So the question is, is it worse with the filled in boxes,  
which use "create polygon" instead of "create line"?

Also it would be good to compare to pd-vanilla 0.40-2.  It should be  
possible to time the opening of a patch using [realtime], having real  
numbers would be quite useful.
