Bug 1210 - Add CoglColor API

	* clutter/cogl/cogl-color.h:
	* clutter/cogl/cogl.h.in:
	* clutter/cogl/common/Makefile.am:
	* clutter/cogl/common/cogl-color.c:
	* clutter/cogl/gl/Makefile.am:
	* clutter/cogl/gl/cogl.c:
	* clutter/cogl/gles/Makefile.am:
	* clutter/cogl/gles/cogl-texture.c:
	* clutter/cogl/gles/cogl.c: Add a new color-type, to be used by
	COGL. CoglColor is optimized to allow the minimum amount of
	conversions possible for both GL and GLES implementations.

	* clutter/clutter-actor.c:
	* clutter/clutter-clone-texture.c:
	* clutter/clutter-entry.c:
	* clutter/clutter-main.c:
	* clutter/clutter-rectangle.c:
	* clutter/clutter-stage.c:
	* clutter/clutter-texture.c: Use CoglColor when needed.

	* clutter/pango/pangoclutter-render.c: Use CoglColor when needed.

	* doc/reference/cogl/cogl-docs.sgml:
	* doc/reference/cogl/cogl-sections.txt: Update the documentation.

	* tests/test-cogl-offscreen.c:
	* tests/test-cogl-primitives.c:
	* tests/test-cogl-tex-convert.c:
	* tests/test-cogl-tex-foreign.c:
	* tests/test-cogl-tex-getset.c:
	* tests/test-cogl-tex-polygon.c:
	* tests/test-cogl-tex-tile.c:
	* tests/test-paint-wrapper.c: Update the tests.

	* README: Update release notes.
