+Small problem with this approach: Resumes can happen before suspend actions!
+This can wreak havoc with things like snapper/preview states and the like...
+
+Actually, this stuff seems to be pretty useless. Not sure what is accomplished
+by this crap. The only thing I can think of is that it would cause a preview
+to be removed if the mouse goes out of the drawing window, could be a legit
+purpose but this seems too retarded for that. Why wouldn't you just code that
+into GraphicView itself and be done with it?
