Clutter 1.21.6                                                       2015-03-03
===============================================================================

 • List of changes since Clutter 1.21.4

   - Support quad-buffer stereo displays on X11/GLX
   This allows using Clutter to draw on GLX framebuffers with the stereo
   bit set.

   - Add a Mir windowing system backend
   This allows using Clutter applications natively on systems using the
   Mir display server.

   - Depend on Cogl ≥ 1.19 and Cairo ≥ 1.12
   Cogl 1.19 is needed for the newly added Mir windowing system backend,
   as well as the quad-buffer stereo display on X11. Cairo 1.12 is needed
   for dropping the ad hoc check for the device scale parameter used with
   ClutterStage implementations as well as the ClutterCanvas content.

   - Improvements in the evdev input backend

   - Use the GdkFrameClock to drive the ClutterMasterClock
   When using the GDK backend, we want the ClutterMasterClock to be driven
   by the GdkFrameClock, as the latter is automatically frame limited by
   the compositor, which gives better results for client applications.

   - Updated translations
   Spanish, Hebrew, Hungarian, Czech, Basque, Russian, Slovenian, Galician,
   Chinese (Taiwan), French, Brazilian Portuguese, Lithuanian, Serbian.
