You could look at the /FontBBox entry in the font dictionary anc compute
the scaling factor (ant thus the "font height") from the FontBBox and the 
pitch value you get from PCL.
Note that this only makes sense for fixed pitch fonts. And note that the 
/isFixedPitch value in the /FontInfo dictionary isn't always reliable for 
determining if the font is fixed pitch or not.
