List all possible kerning pairs combinatorial.
Specifying possible kerning for each character's shape via numbers.
1, 0, -1 represents outside, normal, inside
For 5 vertical positions: ascender, x-height, middle-lower-case, baseline, descender
This might be the minimum resolution to represent common (sans-serif) typedesigns.
You can expand this schema to any resolution you might need to represent
more complex (serif) typedesigns.
This scripts generates SVG vector graphics to visualize the specifications.
