>From the PDF spec:

--- snip ---

The PostScript names of 14 Type 1 fonts, known as the standard fonts,
are as follows:

Times-Roman
Times-Bold
Times-Italic
Times-BoldItalic

Helvetica
Helvetica-Bold
Helvetica-Oblique
Helvetica-BoldOblique

Courier
Courier-Bold
Courier-Oblique
Courier-BoldOblique

Symbol
ZapfDingbats

These fonts, or their font metrics and suitable substitution fonts, are guaranteed
to be available to the viewer application.
...
Ordinarily, a font dictionary that refers to one of the standard fonts should omit
the FirstChar, LastChar, Widths, and FontDescriptor entries.

After inspecting ghostscript and pdftex sources regarding font
selection rules and substitution I came to the conclusion to limit the
use to the fonts above. Any application should be able to use this
sort of files. Everything more is higher magic and IMO beyond the
scope of gl2ps (and my time). Could you state this in the docu,
Christophe - no, not my lack of spare time :) - but maybe a hint
concerning the allowed font names ?
