The sweep under Offset Path (linesweeper 0.4) never finished on some
miter offsets: on the reported glyph and on a synthetic outline it kept
allocating until the app ran out of memory. linesweeper 0.5 fixes that
infinite loop ("Fixed an infinite loop", 0.5.0 changelog), and builds
without changes.
0.5 can hand back a curve piece that doesn't follow the input curve it
was cut from. In the Shape Builder rosette test, a contour runs out along
one petal and back by such a piece, which became a 59 x 4 pt hole in the
merged shape. Tidy::repair rebuilds a piece that strays from the one input
curve through both its ends as that curve's exact sub-curve (input curves
are indexed by their bounds' left edge, so it stays cheap). The there-and-
back then encloses nothing and is dropped as a sliver. Pieces on their
curve, and pieces whose ends two input curves pass through (a real lens),
are left alone.
