Subject: get current font height or scalefont factor

Hi,

This might be a trivial question to ask but I just couldn't find the answer
on the red and blue book. Is there a command to return the current
scale factor a font used in scalefont? Or better, is there a command that
will return the curent height of a font? My faith in PostScript tells me
that if they have stringwidth, they should have something like stringheight,
but I couldn't find anything similar.

I am writing something that needs to know the maximum character height of
a scaled font. Ideally I want to get the maximum height of a string of a
particular font, which is a local maximum depending on the characters (i.e.
aero will have a smaller font height than AERO). Right now I am defining the 
scale explictly as a variable so that I can refer to it later but that's
not flexible/intelligent enough to do the job. Any help will be appreciated.

Andy
