When the max cost for finding a path gets to high, the diff can now be aborted. Because render nodes have a fallback method (by just marking the whole bounds of the nodes as different), we use this to improve performance of diffs. This brings fishbowl (which is basically a container node with N images that change every frame) back to close to previous performance.
