- The ImageWallpaper wasn't watching for the desired dimensions to change, at which point it needs to resize its surface. - The system process has been running with the small dalvik heap limit, which is too tight with these huge wallpapers; this would cause switching wallpapers to eventually stop working as it couldn't get the memory it needed to load the new one. - The compatibility mode background surface had a bunch of issues, such as moving its windows to the right by the window size to make them disappear. This of course doesn't play well with the now super-sized wallpaper surface. This code is re-worked to not require such shenanigans. Change-Id: I64fde4059645d8507f1c4761ba6c17b89877a5c0
