Hello Performers,

pfTraverser seems to have no member function that return the
depth of the current matrix stack, or return the stack itself
(which has the depth info). Are there other ways to get the
xform depth? I want to check depth to see if xform is really
necessary (i.e. if there're dcs etc on the path). Any
suggestions are welcome. Thanks!

Hansong
