/**
 * Draw a hop where two edges cross.
 *
 * Runs as `afterPaint`, because a hop is a property of the rendered path rather
 * than of the layout: the crossings are only known once every edge has been
 * emitted, and the fix is to rewrite the `d` of the edge that gives way.
 *
 * ELK's curve is compatible either way — `applyElkEdgeLayout` sets `rounded`
 * for a routed edge and `linear` for its straight-line fallback, and
 * `curveSupportsLineHops` accepts both. An edge that takes a hop loses its
 * corner rounding in exchange, which is the trade the line-jump module
 * documents.
