pub const MAX_ARC_PIECES: usize = 32;Expand description
The most arc pieces a fitted contour may carry before the fit is discarded and the figure stays a polyline.
A bound on the uniform the chain rides in, and a bound on the point of doing it at all: an arc piece costs more per pixel than a line segment, so a fit that did not collapse the count is not worth evaluating.
The chains the scene actually draws top out at 24 pieces, on the 4-cubic
blob of core/tests/path_cost.rs’s arc comparison; the circle there fits in
6 and the leaf in 16. the_arc_fit_reports_what_a_curve_costs_in_pieces
reads 25 for that same blob at this same budget because it refits the
64-point resample, where PathShape::from_dense fits the dense flatten.
