This adds "usage" param into the reply message of the request quota operation.
That is necessary to implement new Quota Management API [1] behind a flag.

Generate container icons for generated streamlined hosted apps.

When generating apps from web pages, rather than stretching small favicons for
use on the taskbar, chromeos shelf, or app launcher, generate an icon which is
a rounded rect with a strip of the app icon's dominant color and lay the 1x
icon in the centre of this container.

See bug for screenshots.

Fix AppListServiceMacInteractiveTest.ShowAppListUsingShim on Snow Leopard and re-enable.

Threaded animations are crashy on Snow Leopard. Since there's not much
test coverage for Lion either, this CL falls back to non-threaded
animations for Snow Leopard and Lion for showing the Mac App Launcher.
