	wkorman 2016/08/18 23:48:11 This new test is a version of flackr@'s fast/scrol This new test is a version of flackr@'s fast/scroll-behavior/overflow-scroll-with-local-background-and-text.html revised to be a repaint test, and removing border: 10px from #scroller since I didn't deem it relevant for this purpose. Perhaps this should be in paint/invalidation subdir, but I put it here alongside other similar overflow-scroll-* repaint tests.
