https://launchpad.net/bugs/1184812
* New upstream release
* Sync with Debian (LP: #1184812) Remaining changes:
  - debian/patches:
    + 04_compute_average_color.patch: Compute the avergage color in
      gnome-desktop itself, not in unity to fix some races (LP #963140)
    + tweak_color_computation.patch, Patch from Gord, no patch header,
      no bug link.
    + git_revert_draw_background.patch
    + ubuntu_language.patch, Ported relevant bits from g-c-c 
      52_region_language.patch, as required for gnome 3.8 region panel
    + ubuntu_language_list_from_SUPPORTED.patch,
      adds api to get list of available languages from SUPPORTED file.
      To be used by gnome 3.8 region panel language installation.
  - debian/control.in:
    + Don't break gnome-shell << 3.7.90
    + Use source:Version for gnome-desktop3-data Depend
    + Add epoch to gnome-desktop3-data's Breaks/Replaces, as our old
      gnome-desktop source package introduced an epoch. This needs to be
      kept until after 14.04 LTS.
 - Install helper tools into a versioned directory (by overriding
   libexecdir). They could alternatively be installed in a separate package
* Dropped changes:
  - 02_refuse_to_break_GL_compositors.patch:
    + Doesn't appear to be needed any more
