LibPDF: Stub out type3_font_set_glyph_width*

Browse source 
Type 3 font glyphs begin with either `d0` or `d1`. If we bail out
with an "unsupported" error on the very first operator in a glyph,
we'll never paint the glyph.

Just stub these out for now. We probably want to do more in here in
the future (see "TABLE 5.10 Type 3 font operators" in the 1.7 spec).
