Release the Qwaq VMProfiler as VMProfiler. This version derives
from Qwaq-VMProfiling-eem.65. Thanks to all at 3D ICC, especially
Ron Teitlebaum, for permission to release this.
In memory of Andreas Raab, who gave me the opportunity to build
Cog, and who was my friend and colleague. I miss you, Andreas,
very much.

A variant of its superclass that allows multiple items to be selected simultaneously. There is still a distinguished element which is selected, but each other element in the list may be flagged on or off. This is a clone of PluggableListMorphOfMany that sends the changePrimarySelection: selector only when the mouse is first pushed and sends the changeListSelection: selector while the mouse is being dragged. This allows the model to choose to respond to a new selection by deselecting existing selections. This differs from PluggableListMorphOfMany which sends both selectors all the time.!
