The aspect ratio doesn't really have anything to do with it.  R just 
doesn't keep a record of where it has drawn text, so it reports on a box 
that includes everywhere it might have drawn text.  GS actually pays 
attention to what's there and what's not.

R's method makes sense if you want a series of plots to be handled in 
the same way, regardless of whether they actually have titles and labels 
and such.
