Detailed Description

The drawn outline against the disc union.

What the GUI draws is meant to be the boundary of what the pipe paints. The two maps the raster is judged against bound that boundary from both sides – a boundary point is outside the owed map (the union shrunk by two pixels) and inside the permitted one (grown by three) – so every border sample the outline keeps must land in that band. One that lands deep inside the union is a fold, a joint arc or a crossing the outline failed to hide (issue #1352's chords); one outside the permitted map is a spoke to nowhere (issue #1360). Counts both, and how long the GUI-side build took, which is the cost a drag pays.
