Release Notes for Clutter 1.10
-------------------------------------------------------------------------------
+• ClutterDeformEffect switched from using CoglVertexBuffer to using the
+ CoglPrimitive API internally, to improve performance and use non-deprecated
+ Cogl API. CoglPrimitive converts COGL_WRAP_MODE_AUTOMATIC to
+ COGL_WRAP_MODE_CLAMP_TO_EDGE, unlike CoglVertexBuffer which converts it to
+ COGL_WRAP_MODE_REPEAT. This prevents artifacts when sampling texture
+ coordinates outside the [ 0, 1 ] range. This change may cause the back
+ texture to not be painted if its coordinates go outside the allowed range,
+ for instance when using a custom transformation matrix on the back material
+ used by the ClutterDeformEffect.
+
• The "default stage" has been deprecated; since the 1.0 release, the default
stage creation was deferred to the call to clutter_stage_get_default(), and
the preferred way for getting a ClutterStage was calling clutter_stage_new()
