* clutter/clutter-private.h: Add our own READABLE, WRITABLE and READWRITE paramspec flags, declaring the string components of the properties GParamSpec as static; this should shave off some bytes in the memory footprint and avoid relocations. * clutter/clutter-actor.c: * clutter/clutter-behaviour.c: * clutter/clutter-behaviour-opacity.c: * clutter/clutter-behaviour-path.c: * clutter/clutter-behavuour-scale.c: * clutter/clutter-clone-texture.c: * clutter/clutter-label.c: * clutter/clutter-rectangle.c: * clutter/clutter-stage.c: * clutter/clutter-texture.c: * clutter/clutter-timeline.c: Use the CLUTTER_PARAM_* macros we just added. * clutter/clutter-behaviour-scale.c: Add properties for the scale begin, scale end and gravity parameters. * clutter/clutter-behaviour-path.h: Mark the ClutterKnot memory management functions as public (for the bindings), since we use the slice allocator for copying knots around; add a clutter_knot_equal() function. * clutter/clutter-behaviour-path.c: (node_distance): Use clutter_knot_equal() as a fast path to avoid the sqrt() in case the nodes we are using are at the same position. (path_total_length): Additional check on the existence of the next node. * examples/behave.c: Do not leak the ClutterBehaviour objects around.
