formerly both "foo.pfb" and "!foo.pfb" were possible, but they had
different meaning: "foo.pfb" means "read the font file to extract all
parameters but do not embed it" while "!foo.pfb" means "don't read
anything", and the font descriptor is not created. "!foo.pfb" only works
if the font is installed onto the system where the pdf is being viewed
-- it works more or less similarly to the 14 base fonts, except that the
14 base fonts are built into acroreader while foo.pfb must be installed
onto the system properly (which is not easy at all on unix systems).

The reason I implemented it was that I though it would speed up the time
