An expanded stroke: vertices in the XY plane and the triangles over them.
The same division of labour triangulatePolygon draws — this function
has to place its own vertices, because a stroke's vertices do not exist
until it is expanded — with the same guarantee about the triangles: every
one is counter-clockwise seen from +Z (§7a).
