ParallelRasterEdgeIndexPatch

Under Construction

This documentation is auto-generated, and is a work in progress. Please see the source code at https://github.com/phetsims/alpenglow/blob/main/js/parallel/raster-clip/ParallelRasterEdgeIndexPatch.ts for the most up-to-date information.

Overview

Updates the edges with the correct chunk indices (clippedChunk => outputChunk) and first/last flags.

NOTE: It was possible to attempt to set first/last flags earlier (when we wrote the edges), but it would require more traversal for edges that were fully clipped at the start/end (so they didn't contribute at all). We would instead have to find the first/last "non-degenerate" EdgeClip, so it's just easier to do it here.
