Benjamin Otte	200bbe8fda	diff: Allow aborting a diff ... 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.	2018-04-05 14:56:38 +02:00

Benjamin Otte	a6079b9b7b	gsk: Implement gsk_render_node_diff() ... This includes a copy of the diff(1) algorithm used by git diff by Davide Libenzi. It's used for the common case ofcontainer nodes having only very few changes for the few nodes of child widgets that changed (like a button lighting up when hilighted or a spinning spinner).	2018-04-05 14:56:38 +02:00
