New trellis settings

Specifically, I have some code that in the past changed the
relative proportions of text versus the plot area using:

  trellis.par.set('fontsize', list(text=8))

which caused all text to get smaller, and the plot area to grow
to fill the larger available space.  Now, the plot area does not
grow on its own.

That does seem to have been a side-effect in 1.9.1, but it was
never intended. I would consider that behaviour a bug, not a
feature.

It was a pretty convenient bug! ;)

str(trellis.par.get()$layout.heights)

List of 18
 $ top.padding      : num 1
 $ main             : num 1
 $ main.key.padding : num 1
 $ key.top          : num 1
 $ key.axis.padding : num 1
 ...

I was hoping that the names would be enough of a hint. Anything
with 'padding' in the name is space, and probably the ones you want
to change.

I've fiddled with these and can pretty much get what I want.  But
without really understanding what I'm doing.  It isn't clear to me,
for instance, why the "key" settings affect my plot when no key is
drawn.
