» Add an "Effects" chapter to the Clutter Cookbook.
» Queue a redraw and/or a relayout whenever a ClutterActorMeta that
changes the appearances or the allocation of an actor is enabled
or disabled.
» Fix the error reporting of the initialization sequence; this change
makes Clutter abort early and with a meaningful message on backend
initialization errors, instead going ahead and printing less than
useful error messages.
» Disable blending when using a texture render during a blit.
» Fix handling of opacity when using an OffscreenEffect.
» Tune the point-in-poly checks for the software-based picking.
