We've gotten ourselves into a bit of a mess by mixing pixel and point
sizes in multiple places. Step one towards getting out of this mess
is adding explicit accessors for the unit you're trying to fetch.
The core of the issue comes from bitmap fonts storing integer pixel
sizes and scaled (TTF) fonts storing float point sizes.
This allows bitmap font lookup to return the best matching size instead
of failing completely. The previous behavior (exact matches only)
remains the default.
Fonts now provide their preferred line height based on maximum
height and requested line gap. TTFs provide a preferred line gap
from table metrics while BitmapFonts are hardcoded at the previous
default for now.
This returns a more comprehensible name than raw weight and slope
metrics and is intended for use in UIs. Now displays human readable
font names in FontSettings, TerminalSettings and CharacterMap.
Removes the concept of Type enumeration in favor of a bitmask which
represents 544 potential byte ranges of 256 characters per bit,
supporting the current unicode code point set (0x0000-0x10FFFF).
Range positions are indexed in a vector for code point lookup and
conversion.

This adds a new structure 'Typeface' to the FontDatabase that
represents all fonts of the same family and variant.
It can contain a list of BitmapFonts with varying size but of
the same family and weight or a pointer to a single TTF font
for all sizes of this Typeface.
