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 measured counts at the tightest budget below sit at 25 and under.
