inlinestatic

How many sub-steps bridge the jump between two consecutive feather spokes.

The feather is the union of segments from each outline sample to its border sample, so it stays continuous only while consecutive segments are within a pixel of each other at BOTH ends. At a cut boundary they are not: the border side collapses to the cut's resume point and the fan opens in a single step, leaving a wedge nothing stamps – the thin dark radial line reported as "a radial spoke is missing" at node 12 of polygon #2 in issue #1313's sidecar. One sub-step per pixel of the larger jump closes it.

The two rasterisers differ only in where the bridging spokes GO, so the geometry lives here once and each sink gets its own three-line wrapper below.
