- Bug 1125750 - Check the overflow region direction to avoid unnecesary reflow for scrollable frame. (6b5067631) - Bug 1125750 - Add auto test to detect error when using mOuter to check overflow area of a scrollable frame. (4e9c43e31) - override -> MOZ_OVERRIDE (ed1ecc151) - Bug 990907 - Don't add text-overflow markers while being actively scrolled by APZ. (523bc5a3e) - Bug 945584: Part 6 - Implementation of scroll snapping (v10 Patch) (bf64eb0f3) - Bug 945584: Part 7 - Implement Scroll Snapping for Autoscroll, - Triggering scroll snapping at the end of an autoscroll. - This enables text selection to be unencumbered by scroll snapping, while restoring the scroll position to a valid snapping position when the drag operation is completed. (db9ce9811) - Bug 945584: Part 8 - Implement Scroll Snapping for Middle Mouse Button Scrolls (v2 Patch) (06d1b733d) - some MacOS 10.5 Leopard support (6a37f6745) - Bug 945584: Part 9 - Tests for scroll snapping (v4 Patch) (f67175387) - Bug 1102427 - Ensure scroll parents of an active scrollframe are layerized. (910d43ec5) - Bug 1142731 followup. Check isInterpreted() before we call environment(), because of the asmjs lambdas. (29b2acdc7) - Bug 1161627 - part 1 - add move constructor and assignment operator for already_AddRefed&& to RefPtr; This change is prep work for future mass rewriting. (98416d45c) - Bug 1161627 - part 2 - machine-convert TemporaryRef<T> to already_AddRefed<T>; (336e96af7) - Bug 1161627 - part 3 - remove TemporaryRef<T> from RefPtr.h (6c3acdaed) - Bug 940273 - Part 3 - Service Worker Cache webidl. (4b6803d0a) - Bug 940273 - Part 4 - Initial implementation of Service Worker Cache. (74498c108) - Bug 1133861 - Bustage fix. (4a81437c2)
