From 166db5c8936232da188fbae0c8b0932f92b1df0f Mon Sep 17 00:00:00 2001 From: "enne@chromium.org" <enne@chromium.org@0039d316-1c4b-4281-b951-d872f2087c98> Date: Wed, 9 Jan 2013 23:54:31 +0000 Subject: cc: Generate tilings at other scales for impl-side painting This patch adds infrastructure to make it easy for PictureLayerImpl to manage its set of tilings via PictureLayerImpl::ManageTiles(). The main functionality change is to additionally generate a low-res set of tiles (by default 1/8 resolution). Along with generating tilings at different scales, tile priorities now have the correct resolution set on them so that they can be prioritized correctly. There's a few small bugfixes added here as well for correctness, such as making sure that tilings are sorted in the PictureLayerTilingSet from highest to lowest. (This is the order in which tiles will be used.) It also correctly calculates a synthetic contents scale / content bounds for the PictureLayerImpl to support multiple active contents scales.
