Merge branch 'master' into cogl-float

Browse Source 
The patches have been updated to apply cleanly.

The patches for the g_warnings in clutter-actor.c have been removed
because master now uses CLUTTER_UNITS_FORMAT so they aren't
necessary. The clutter-units.h patch now sets CLUTTER_UNITS_FORMAT to
'f'.
