Replay isn't that helpful of a test any more now that we have the more stringent Quilt tests. Quilt was missing bounding box hierarchies, though, while Replay was sort of testing RTree (pointlessly, as it was drawing without any clip). Now Quilt does everything, testing RTree, QuadTree, and TileGrid. Quilt mode now falls back to drawing all at once (i.e. Replay) for GMs that don't tile perfectly. Still a TODO to make this check more flexible than exact pixel matches. Two GMs fail when using a BBH: - imageresizetiled - resizeimagefilter We think we're not adjusting the bounds of save layers by their paint. This is probably a bug, but one to be fixed separately from adding new tests.
