#893: Shape Builder merges leave no seams on grids of lines

Browse Source

The planar map merged sweep endpoints within eps into one vertex id but
kept each segment's own copy of the coordinates, so faces meeting at a
vertex could disagree on that corner by ~1e-13. Uniting them then failed
to cancel their shared edge, and a merged strip came back as several
touching subpaths whose stroke drew the inner edges as leftover lines.

Pin every edge's ends to its vertex's canonical position, so faces share
their corners bit for bit. Regression test from the reporter's grid.
