Well, the font sizes are as I have had them for ages: 12pt on a 100dpi
assumed resolution. If that's too large, fine, complain and if you
gain a sufficient following we might reduce it to 10pt. The old code
would give you 100dpi or 75dpi fonts depending on which one came first
on your font path and was available at the desired size, leading to
general madness. If it bothers you enough, use fix(X11) and change the
default for the pointsize argument.

(And yes, I'm nearsighted, but remember that you also need to be able
to read the smaller sizes - try a run through demo(graphics))

The postscript is truly bug-ridden, but the latest snapshot should be
much better.

Nope, but we should probably have something like ps.options there, the
par() effect is also messing up example(): the code cannot set
ask=TRUE so multiple graphics in an example just fly by, unless the
user sets the parameter.
