I have a Custom GoNode class which contains a GoText instance for
showing some text. I have also an instance of GoPort with transparent brush and need to show in the same location. At the moment it seems
Text is hiding Port as I am not able to drag a connection from this port
as mouse cursor is not changing to hand when I hover mouse over the
port. Could you suggest a way of making port as top level object so that
connections can be made from it. Since I am using transparent brush
for port, it will not hide text of the GoText.
