question on DisplayRendering

Hello Folks,
how can i set the default display size and still use the VisAD 2D
implementation?  i'd like to set it at 360 by 180 (i,e, to depict a
rectangular latlon grid rather than a square).

i'm having a little trouble understanding whether i can reference the
setPreferredSize method in DisplayPanelJ2D.  is this possible?

thanks,
-john
