v0.2.20

• PATCH: a new subpath export, with no break. In a consumer profile, the text measures and the line breaks take approximately 3.1 s of a first load. Thus text layout is a layout step of the contract.
• The subpath @mark1russell7/layout-contract/text has createMeasurer, canvasAdvance, fontKey, graphemesOf, layoutText, textMeasures and TEXT_MEASURES.
• The measurer caches the advance of each font and word segment, in whole units of 1/64 pixel. Thus each port gets the same lines.
• layoutText has a character clamp, a padding, a min and max width of one line and a wrap width. It also has a max line count with an ellipsis, a line height and a word break option.
• docs/TEXT.md gives the rules, the units, the error and the measures.
