Removed =for ref Internal pod directives

The pod directive =for ref Internal shows up in many places in Graphics/PGPLOT/Window/Window.pm, but it does not serve much of a purpose. It probably served a useful purpose at some point, but that purpose has been lost. Removing for now, with the expectation of revisiting after devising a better pdldoc keyword system.

 To prevent pgplot from doing a fandango on core, we have to block interrupts
 during PGPLOT calls.  Specifically, INT needs to get caught.  These internal
 routines provide a mechanism for that.
