Outline represents a clipping operations that clips all drawing outside a closed path. Before this change, paths not closed we're patched up by adding an implicit line from the endpoint to the beginning. These fixups are inefficient for a rare case, but acceptable because the old renderer post-processes all paths anyway. However, the new compute renderer don't need post-processing in most cases, making fixups too expensive. Given that clipping to an open path is fundamentally undefined and that implicit fixup with a closing line segment is merely a way to force the clip to be well-defined, this change adds a panic to Outline for Paths that are not closed.
