LibPDF: Add very basic support for Adobe Type 1 font rendering

Previously we would draw all text, no matter what font type, as Liberation Serif, which results in things like ugly character spacing. We now have partial support for drawing Type 1 glyphs, which are part of a PostScript font program. We completely ignore hinting for now, which results in ugly looking characters at low resolutions, but gain support for a large number of typefaces, including most of the default fonts used in TeX.
