When it comes to aligning text, it helps to know the standard height of letters.
This isn't quite the same as the ascent, as that tends to include extra space above characters for accents and things.
So this adds the ability to query the cap and x-height of letters (the standard "approximate" height of upper and lowercase characters)
If this info isn't available then it falls back to being the ascent value and 3/5ths of that for lowercase.
(I've no idea if 3/5ths is a good approximation but it looked about right, so seemed reasonable)
