• What's new in Clutter 1.5.2

  - List of changes since Clutter 1.4:

    » Add API to ClutterActor to allow any actor to define its 3D paint
      volume and its stage-relative 2D bounding box; the paint volume is
      the 3D space occupied by an actor during the paint sequence. This
      allows better sizing of the FBOs, and opens the door to scenegraph
      culling and accurate clipped redraws. The mechanism is opt-in:
      actors have to implement the get_paint_volume() virtual function.
      Callbacks attached to the ::paint signal will also disable any
      culling and clipped redraw in place internally.

    » Plug a leak in ClutterActor by disposing all constraints.

    » Rework the build system to be as non-recursive as possible; this
      should speed up the build of Clutter, and makes the build layout
      easier to understand and update.

    » Remove the internal copy of JSON-GLib; the internal copy was
      falling behind at a spectacular level, and it was actually making
      the build rather complicated - also by adding an unwanted, but
      needed, introspection data generation. The required JSON-GLib has
      also been bumped to the new stable release, 0.12.0.

    » Use g_object_install_properties() with GLib 2.26.

    » Implement ClutterContainer::child-notify, which slipped through
      the cracks of many development cycles without anyone noticing.

    » Document and test clutter_actor_contains(), especially the corner
      cases.

    » Plug a leak in CoglTexture2DSliced.

    » Plug a leak in ClutterAnimator's handling of timelines.

    » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid
      BadDrawable errors when the GLX pixmap is destroyed behind Cogl's
      back.
