LibGfx: Report font glyph presence based on glyph's specific width

Browse source 
This uses the per glyph width to determine if the glyph is actually
present in the font, and not just inside the range the font can covers

This means that characters that are in the font's range but that are
missing a glyph will show up as the missing character glyph instead of
being invisible.
