> FontBox's TTF GlyphTable reads the entire glyph table and constructs an object for each glyph. However this is very slow for large external fonts (e.g. Asian) such as "STXihei" which is 15.7MB and has 37255 glyphs. On my machine it takes around 9 seconds for PDFBox to load that font just to render 15 glyphs from it.
> We can modify GlyphTable to make it lazy so that glyphs are read individually only when needed.
