When you print with the Symbol font (from a Mac) integral signs
and the various brackets below 24pt everything behaves normally.

However above 24pt the character is constructed from two characters
(at least the screen font contains upper and lower halves).  This is
sort of nice but a 24pt integral is much different from a 25pt integral
and often you can see a glitch where the two halves meet.

Anyway I suspect this 'constructing' 1 character from two is handled by 
the Mac (nothing to do with postscript)

What is intreresting me is what happens as you scale these characters
to larger point sizes.  The height of the character is increased but
the width and lineweight is not.

Is it possible that this behavior is 'built in' to the font definition
or is the Mac putting a 'scale 1 10' into the ps file?

I'm sure there are other examples of where you might want a non-proportional
scaling.  Just how flexable is a font description?
