* clutter/clutter-model-default.c:
(clutter_model_default_iter_next),
(clutter_model_default_iter_prev): Do not instantiate a new
iterator, and update the passed one instead, as we say we do
in the documentation. This avoid leaking tons of iterators.
* clutter/clutter-model.[ch]: Update the documentation.
* tests/test-model.c: Prettify some output.
* 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.
* clutter/clutter-model.[ch]: Slight API change in the constructor
functions for ClutterModel: clutter_model_new() now takes a list
of GType/string pairs for both the column type and the column name.
(clutter_model_set_n_columns),
(clutter_model_set_names),
(clutter_model_set_types): Subclasses of ClutterModel will be able
to call clutter_model_set_types() and clutter_model_set_names() in
any order, provided that they don't call each function more than
once.
* tests/test-model.c: Update the test case.
