-> Early exploration of AllApps Hero transition with
circular reveal
-> Stripping a bunch of dead code from AppsCustomizeTabHost
-> Moved background scrim to DragLayer
-> Removed "SMALL" state from workspace: replaced with
NORMAL_HIDDEN and OVERVIEW_HIDDEN. This is mainly to
reduce the overall usage of the z-space model between
allapps/widgets and workspace. There are vestigial
remains of this model, mainly due to the overview
mode, and a bit for spring-loaded.
