Add code to track and draw the root window background. The advantage of doing it here as compared to in a plugin is that we can use the visiblity smarts of MetaWindowGroup to optimize out drawing the background when obscured. If handling other than tracking the _XROOTPMAP_ID property is desired in the future, more functionality like setting the background from a file or doing cross-fades can be added. The new background actor is exposed to plugins via meta_plugin_get_background_actor() similar to other exposed actors to allow cloning the background for use in other displays. The actual class is not installed for public consumption at the moment since it has no useful methods. https://bugzilla.gnome.org/show_bug.cgi?id=634833
