From 8d5f83dcec67ad1b428499248a62d0a061260dab Mon Sep 17 00:00:00 2001 From: "vollick@chromium.org" Date: Fri, 18 Oct 2013 15:14:59 +0000 Subject: [PATCH] Add a flag for enabling/disabling the new accelerated scrolling path Relanding. This patch had previously been reverted because opting into the new path could run us into bugs. All known bugs have been resolved, so this should be safe to land. We now have two accelerated scrolling paths. One accelerates scrolling whenever it's safe to promote the overflow scrolling div to a stacking container / containing block and not break stacking or clipping. The new path, the 'universal' path, enables accelerated scrolling in those cases where the old path would not opt-in. Eventually, we'd like to eliminate the old path, but this will require layer squashing (the new path can result in many composited layers that ought to be combined -- i.e., a 'layer explosion'). Until these paths are mature, we need to be able to enable and disable them both, so we have two separate sets of flags. Once we've eliminated the old path, we can replace both with --[enable/disable]-accelerated-overflow-scroll (and eventually get rid of both sets of flags).
