  * Do not use pointers to LazyLoadTextures. (LP: #1569100)
  * Fix unity script crash. (LP: #1566565)
  * LockscreenController: Don't use SetActivate(False) for gnome-
    screensaver to prevent unlocking on tty switch. It will not only
    deactivate the screensaver but also unlock the screen. (LP:
    #1552537)
  * unityshell.xml: Fix typo (LP: #1559427)
