* - 'wide' glyphs have a normalised width of
* 100 * (wide_character_pixel_width / latin_character_pixel_width)
* - When a character is detected, the position in the current
* line is incremented by the regular normalised width of 100
* - If that character is then determined to be a 'wide'
* glyph, the position in the current line is further incremented
* by the difference between the normalised 'wide' and 'non-wide'
