At 50,000 paths unless noted, against main:
- Pathfinder Outline (300 paths): 145 → 7.5 ms. Each segment was tested against every junction
of the arrangement, and each chain against every chain kept so far. Now a segment tests only
the junctions inside its control box (junctions are sorted by x; a point within reach of a
curve is within reach of that box), with the same nearest-point test. Coincident chains are
found through a grid on their midpoints, taking the first match in the same order a scan does.
- export SVG: 267 → 176 ms. Path data is written straight into one string (`push_num`, the
same digits and trimming as `fmt_num`) instead of a string per number, point and segment.
- open .vectorcraft: 239 → 195 ms. The JSON was parsed once only to find where it ends:
- A file with no NUL has no data after it.
- Otherwise the marker (which holds the first NUL, as JSON can't) is taken when it directly
follows the JSON's last byte, as the writer puts it.
- Anything else takes the old parse.
`perf --deep` prints output hashes of an SVG export and a save → open → save round trip; main
and this branch print the same ones. pathfinder_pinned (Outline included) passes, and so do the
pathops, format and svg suites (345 tests).
