Laurenz d101612414 Primitive CFF1 subsetting 
The subsetting strategy is somewhat crazy for now: Simply zero the glyph data for all unused glyphs. While the CFF table itself doesn't shrink, the actual embedded font is compressed and greatly benefits from the repeated zeros.

This already compresses the fonts a lot (~90% for NotoSerifCJK), but they are still quite large.

Therefore, the plan of action:
- First, find more data that can be zeroed out.
- Then _maybe_ see whether we can instead properly rebuild the subsetted font.

Laurenz 54a9ccb1a5 Configurable font edges ⚙ 
Adds top-edge and bottom-edge parameters to the font function. These define how
the box around a word is computed. The possible values are:
- ascender
- cap-height (default top edge)
- x-height
- baseline (default bottom edge)
- descender

The defaults are chosen so that it's easy to create good-looking designs with
vertical alignment. Since they are much tighter than what most other software
uses by default, the default leading had to be increased to 50% of the font size
and paragraph spacing to 100% of the font size.

The values cap-height and x-height fall back to ascender in case they are zero
because this value may occur in fonts that don't have glyphs with cap- or
x-height (like Twitter Color Emoji). Since cap-height is the default top edge,
doing no fallback would break things badly.

Removes softness in favor of a simple boolean for pages and a more finegread u8
for spacing. This is needed to make paragraph spacing consume line spacing
created by hard line breaks.

Laurenz bbb9ed07ff Better line spacing calculations ↕ 
- Only add line spacing between lines. Previously, line spacing was added below
  every line, making `#box[word]` higher than just `word`.
- Compute box height of text as `ascender - descender` so that the full word is
  contained in the box.
