I would like to see retro_inline.h moved in here; possibly boolean too.
rationale: these are used in public APIs, and it is easier to find problems
and write code that works the first time portably when theyre included uniformly
than to do the analysis from scratch each time you think you need it, for each feature.
Moreover it helps force you to make hard decisions: if you EVER bring in boolean.h,
then you should pay the price everywhere, so you can see how much grief it will cause.
Of course, another school of thought is that you should do as little damage as possible
in as few places as possible...

* width of regular Latin characters:
* - Regular 'non-wide' glyphs have a normalised width of 100

* - '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'
