Sufficient solution to the problem for now -- adding the option 
aspect="fill" fills the window, and if I specify the size of the window, 
then this amounts to the same thing, more or less.

Seems kind of a backward way to do it. I'd have thought setting size of 
the graphic, and then having the window size change dynamically around 
said graphic, would have been more intuitive.
