A PDFFont can now be asked for its specific type and whether it is part of the standard 14 fonts. It now also contains a method to draw a glyph, which is stubbed-out for now. This will be useful for the renderer to take into consideration when drawing text, since we don't include replacements for the standard set of fonts yet, but still want to make use of embedded fonts when available.
