TextDecorationStyle

Remarks

⚠ Four of CSS's five, and this used to be two. dashed and dotted were absent because there was no dash pattern anywhere in Vixen.Ui — the same measurement border-style, divide-<style> and outline-<style> were all recorded under, four families reading partial for one missing thing. There is one now: Dashes distributes the marks and DrawListBuilder emits a rectangle each.

⚠ A bar is the easy consumer of that pattern and it is worth saying why. A decoration is an axis-aligned rectangle with no corner radius, so breaking it up is breaking up a length — no path, no stroke, no tessellation, and the software rasteriser and the device draw the pieces because they are drawing the same quad they already drew. A border's ring is the hard one, and it is hard for the corners rather than for the pattern.

⚠ wavy stays absent, and it is absent for a reason the dash pattern does not touch. A wave is a stroked path where every other decoration is a rectangle: it needs the tessellator, a thickness that is a stroke width rather than a height, and an amplitude and a period CSS does not state. A decoration-wavy that resolved and painted a straight line is the inert family UtilityConsumptionGateTests exists to keep out.
