Neil Roberts 1a63414966 Bug 1252 - Merge ClutterBehaviourPath and ClutterBehaviourBspline
* clutter/clutter-path.h:
	* clutter/clutter-path.c: Implementation of new ClutterPath object
	to represent a path combining straight line and bezier curve
	elements.

	* clutter/clutter.h: Include clutter-path.h and remove
	clutter-behaviour-bspline.h

	* tests/interactive/test-threads.c (test_threads_main):
	* tests/interactive/test-script.c:
	* tests/interactive/test-behave.c (test_behave_main): Use new path
	API

	* clutter/clutter-effect.c: Use the new ClutterBehaviourPath API.

	* clutter/clutter-bezier.h:
	* clutter/clutter-bezier.c: Moved bezier curve handling code out
	from clutter-behaviour-bspline.c to a separate file.

	* clutter/clutter-behaviour-path.h:
	* clutter/clutter-behaviour-path.c: Reimplemented to work with a
	ClutterPath

	* clutter/clutter-behaviour-bspline.h:
	* clutter/clutter-behaviour-bspline.c: Removed

	* clutter/Makefile.am: Add clutter-path and clutter-bezier, remove
	clutter-behaviour-bspline.

	* tests/conform/test-path.c: New automatic test for ClutterPath
	consistency

	* tests/conform/test-conform-main.c (main): Add test_path

	* tests/conform/Makefile.am (test_conformance_SOURCES): Add
	test-path.c

	* clutter/clutter-sections.txt: Add ClutterPath docs

	* clutter/clutter.types:
	* clutter/clutter-docs.xml:
	* doc/reference/clutter/clutter-animation-tutorial.xml: Remove
	mention of ClutterBehaviourBspline

	* clutter/clutter-marshal.list: Add VOID:UINT
