* 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/Makefile.am: * 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-offscreen.c: * tests/interactive/test-cogl-primitives.c: * tests/interactive/test-cogl-tex-convert.c: * tests/interactive/test-cogl-tex-foreign.c: * tests/interactive/test-cogl-tex-getset.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.
