* clutter-color.h:
	* clutter-color.c: Reimplement ClutterColor as a boxed type;
	add convenience API for color handling, like: add, subtract,
	shade, HSL color-space conversion, packing and unpacking.

	* clutter-private.h: Update ClutterMainContext, and export the
	main context pointer here.

	* clutter-rectangle.h:
	* clutter-rectangle.c: Update the color-related code; make
	clutter_rectangle_new() and empty constructor and provide
	clutter_rectangle_new_with_color(); provide color setter
	and getter API.

	* clutter-label.h:
	* clutter-label.c: Rename the "font" property to "font-name";
	update the color-related code to the new ClutterColor object;
	rename clutter_label_new() to clutter_label_new_with_text(),
	and add setters and getters for the properties.

	* clutter-marshal.list: Add VOID:OBJECT and VOID:BOXED marshallers
	generators.

	* clutter-stage.h:
	* clutter-stage.c: Rework the API: provide a default constructor
	for a singleton object, named clutter_stage_get_default(), which
	supercedes the clutter_stage() function in clutter-main; provide
	new events: button-press-event, button-release-event,
	key-press-event and key-release-event; update the color-related
	code;

	(clutter_stage_snapshot): Allow negative width and height when
	taking a snapshot (meaning: use full width/height).

	(clutter_stage_get_element_at_pos): Rename clutter_stage_pick().

	* clutter-element.c (clutter_element_paint): Clean up the
	stage and color related code.

	* clutter-event.h:
	* clutter-event.c: Add generic ClutterAnyEvent type; add
	clutter_event_new(), clutter_event_copy() and clutter_event_free();
	make ClutterEvent a boxed type.

	* clutter-main.h:
	* clutter-main.c: Remove clutter_stage(); add clutter_main_quit(),
	for cleanly quitting from clutter_main(); add multiple mainloops
	support; allocate the ClutterCntx instead of adding it to the
	stack; re-work the ClutterEvent dispatching.

	* clutter-group.c (clutter_group_add), (clutter_group_remove): Keep
	a reference on the element when added to a ClutterGroup.

	* examples/rects.py
	* examples/test.c:
	* examples/test-text.c:
	* examples/video-cube.c:
	* examples/super-oh.c:
	* examples/test-video.c: Update.
