* clutter/cogl/cogl-color.h:
	* clutter/cogl/cogl-path.h:
	* clutter/cogl/cogl-types.h:
	* clutter/cogl/common/cogl-color.c: Deprecated cogl_color()
	in favour of cogl_set_source_color() and friends; store the
	CoglColor components as unsigned bytes instead of fixed point
	normalized values; add functions for allocating, copying and
	freeing CoglColor, for use of language bindings.

	* clutter/cogl/cogl.h.in:
	* clutter/cogl/cogl-deprecated.h: Added cogl-deprecated.h,
	an header file containing the deprecation symbols similar
	to clutter-deprecated.h.

	* clutter/cogl/gl/cogl-texture.c:
	* clutter/cogl/gl/cogl.c:
	* clutter/cogl/gles/Makefile.am:
	* clutter/cogl/gles/cogl-texture.c:
	* clutter/cogl/gles/cogl.c: Update the GL and GLES implementations
	of COGL after the CoglColor changes.

	* clutter/clutter-actor.c:
	* clutter/clutter-clone-texture.c:
	* clutter/clutter-entry.c:
	* clutter/clutter-label.c:
	* clutter/clutter-rectangle.c:
	* clutter/clutter-texture.c: Do not use CoglColor whenever it
	is possible, and use cogl_set_source_color4ub() instead.

	* clutter/pango/cogl-pango-render.c: Ditto as above.

	* doc/reference/clutter/subclassing-ClutterActor.xml:
	* doc/reference/cogl/cogl-sections.txt: Update the documentation.

	* tests/interactive/test-cogl-tex-foreign.c:

	* tests/interactive/test-cogl-tex-polygon.c:
	* tests/interactive/test-cogl-tex-tile.c:
	* tests/interactive/test-paint-wrapper.c: Drop the usage of
	CoglColor whenever it is possible.
