[cairo] Font issues in PS and PDF

 I solved my compiler problems and tried out your fix. It's better, but it
still has some problems:

- Illustrator no longer complains about certain fonts. If a font weight or
slant is used, however, there are still problems. It tacks the font weight
to the end of the font name (eg "GaramondBold"). Illustrator doesn't realize
that this is Garamond with the Bold style. Fonts like "Times New Roman" get
scrunched together as "TimesNewRoman", also giving errors.

- TrueType fonts still have the wrong glyphs. It looks fine as a PDF render,
but letters turn into boxes once it is opened in Illustrator. Curiously, if
I use Adobe Acrobat to change the font in the PDF, save, then open in
Illustrator, all the glyphs are correct.

OpenType fonts now have the correct glyphs. The only problem is that the
spaces get removed in the font name. If I set the font back manually, it all
works fine.
