If the font dictionary didn't specify custom glyph widths, we would fall back to the specified "missing width" (or 0 in most cases!), which meant that we would draw glyphs on top of each other in a lot of cases, namely for TrueTypeFonts or standard Type1Fonts with an OpenType fallback. What we actually want to do in this case is ask the OpenType font for the correct width.
