so. Otherwise, returns -1. The argument is used only internally
and should always be 0, except for internal use. Actually, the
argument works in the following manner: if pass==0, then the
method looks for pk-fonts and virtual fonts, and disables
automatic pk generation, even if it is turned on with the
setMakePK-method. If pass!=0, then only pk fonts are looked for,
and fonts are generated, if necessary. This method works in
stages: first, it is called with pass=0, and vf-fonts are
loaded. These may define further pk-fonts. The pk-fonts will be
