I just committed these changes to CVS.  I've added
Set/GetDesiredUpdateRate and Set/GetStillUpdateRate methods to the Tk,
wxPython and Qt widgets.  I cannot test the Qt widget and would
appreciate if someone could just take a look at it.  These changes
(very small) allow one to use LOD actors along with these widgets.  So
far it seems to work well.  At the end of the email is a sample
Tkinter app that demos it.  Let me know if there are problems.

cheers,
