Browse Source 
* clutter/clutter-behaviour.c:
	(clutter_knot_get_type): Use the I_() macro.

	* clutter/clutter-model.[ch]: Make ClutterModel and ClutterModelIter
	abstract classes; also, provide more virtual functions inside the
	ClutterModel vtable, to allow subclasses and language bindings to
	override the entire ClutterModel using other/native data types
	to store the rows.
	
	* clutter/clutter-model-default.[ch]: ClutterModelDefault is a
	default implementation of ClutterModel and ClutterModelIter using
	GSequence.

	* clutter/Makefile.am:
	* clutter/clutter.h: Build glue for ClutterModelDefault.

	* tests/test-model.c: Update for constructor changes.

	* tests/test-shader.c: Fix a typo.

/**
* SECTION:clutter-model-default:
* @short_description: Default model implementation
*
* #ClutterModelDefault is a #ClutterModel implementation provided by
* Clutter. #ClutterModelDefault uses a #GSequence for storing the
* values for each row, so it's optimized for insertion and look up
* in sorted lists.
*
* #ClutterModelDefault is a terminal class: it cannot be subclassed,
* only instantiated.
*
* #ClutterModelDefault is available since Clutter 0.6
