This is (or was) an important part of the connectivity() routine.
Pushnetwork() creates a hierarchy stack to make sure the correct CTM
is in place when highlightnetlist() is called, because the net being
highlighted is not necessarity present on the top level of the hierarchy.
However, depending on how highlightnetlist() is implemented, if it
is part of the drawing code, then it will presumably draw the netlist
highlight as needed when it reaches the right level of the hierarchy,
in which case the drawing stack is already generated by the drawing
routine.
If you already removed highlightnetlist() and put it into the drawing
code, then that is no doubt why you see an unused matrix stack. I
think that the way you have rearranged the code, it is safe for you
to remove pushnetwork().
