We now have ClutterTouchpadPinchEvent and ClutterTouchpadSwipeEvent,
each bringing the necessary info for the specific gesture. Each
of these events is defined by begin/update/end/cancel phases.
These events have been also made to propagate down/up the pointer
position, just like scroll and button events do.
When binding models to actors to map items to children we don't often
need the full control of a function; in many cases we just need to
specify the type of the child we want to construct and the properties
on both the item and the child that we want to bind.
We should provide a simple convenience function that does all this for
us.
It can be useful to bind the children list to set of objects inside a
GListModel implementation; the GListModel stores the objects, and every
time the model changes, a function is called that maps each object in
the model to a newly created ClutterActor, which is then added as a
child. This API, along with the property binding one inside GObject,
allows automatic creation of views based on object models that update
themselves without manual intervention.
Straight from Cogl.
This allows us to propagate the GdkVisual Cogl and Clutter use to
embedding toolkits, like GTK+.
The function is annotated as being added to the 1.22 development
cycle because it will be backported to the stable branch, so that
downstream developers can package up a version of Clutter that does
not crash on nVidia.

* clutter/clutter-units.h:
* clutter/clutter-fixed.h: Add boundaries for fixed point
and units values.
* doc/reference/clutter-sections.txt: Update the documentation.
* clutter/clutter-fixed.[ch]: Add a ClutterFixed fundamental
type, and wrappers for storing it into GValues; also add a
GParamSpec subclass for defining parameters holding
ClutterFixed values. This allows creating GObject properties
using fixed point values.
* doc/reference/clutter-sections.txt: Document the newly
added API.
* clutter/Makefile.am: Add clutter-units.c
* clutter/clutter-units.[ch]: Add a ClutterUnit fundamental
type, and wrappers for storing it into GValues; also add a
GParamSpec subclass for defining parameters holding ClutterUnit
values. This allows creating GObject properties using units.

added API.
* clutter/win32/clutter-win32.h:
* clutter/win32/clutter-stage-win32.h:
* clutter/win32/clutter-stage-win32.c:
* clutter/win32/clutter-event-win32.c:
* clutter/win32/clutter-backend-win32.h:
* clutter/win32/clutter-backend-win32.c:
Upgraded for multi-stage support.
* clutter/win32/clutter-stage-win32.c
(clutter_stage_win32_request_coords): Fixed so that it doesn't set
the position or size if it hasn't changed. This was causing
problems when the window was resized using the top left corner. In
that case the window receives resize and move messages separately
which caused the window to flash at a different size or position
while one message was handled before the other.
(clutter_stage_win32_realize): Added PFD_GENERIC_ACCELERATED to
the list of pixel format flags to force it to use hardware
acceleration.
2008-03-30 Neil Roberts <neil@o-hand.com>
* clutter-sections.txt: Added clutter_win32_get_stage_from_window
* clutter/win32/clutter-win32.h: Added gtk-doc documentation for
the Win32 backend section.

API.
* clutter-docs.sgml: Added comments about the Win32 backend.
* Makefile.am: Added bits to ignore the headers for the Win32
backend.
* clutter/clutter-score.[ch]: Remove all the API changes, and
just add a clutter_score_append_at_marker(); the implementation
remains the same, but the marker must be explicitly created by
the developer. The ids are no longer used to create implicit
markers, so they can return to be unsigned integers.
* clutter/clutter-timeline.[ch]:
(clutter_timeline_has_marker): Add a function to query a timeline
for a marker being set.
* tests/test-score.c (main): Update with the API changes.

* clutter/clutter-main.h: Make clutter_do_event() public again,
as we need it in clutter-gtk.

* clutter/x11/Makefile.am:
* clutter/x11/clutter-x11.pc.in: Add a clutter-x11 pkg-config
file for clutter-gtk, as it depends on the X11 backend API, as
implemented by the GLX and EGLX backends.
* clutter/x11/clutter-event-x11.c (event_translate): Do not
propagate DestroyNotify events if the stage doesn't own the
window.

and clutter_behaviour_opacity_get_bounds() to the list of
public symbols.

into ClutterListModel, to make it clear that the default
ClutterModel implementation is list-based
* tests/test-model.c: Update call
* clutter/clutter-model-default.[ch]: Remove the ClutterModelDefault
iterator symbols from the public API; the iterator implementation
is a detail of the default ClutterModel class
* clutter.symbols: Update
* clutter/clutter-model.h:
* clutter/clutter-model.c:
(clutter_model_appendv),
(clutter_model_prependv): Add vector based API for bindings.

the pixels-based clip accessors as proxies for the units-based
ones
* clutter/clutter-group.c:
* clutter/clutter-group.h: Add the clutter_group_add() convenience
function; it's now "undeprecated" and implemented as a macro
* clutter/clutter-stage.h: Add clutter_stage_add() as a convenience
macro
* clutter/cogl/cogl.h: Include just the needed headers instead
of the whole clutter.h; this avoids rebuild cogl when not needed
* 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.

default implementation of ClutterModel and ClutterModelIter using
GSequence.

(clutter_model_insert_value): Add a _value() variant for the
insertion methods, for use of the language bindings.
(clutter_model_append),
(clutter_model_prepend),
(clutter_model_insert): Do not return a boolean: insertion should
never fail unless for a programming error, in which case we have
plenty of warnings.
* clutter/clutter-score.[ch]: Reimplement ClutterScore using
a N-ary tree to store the timelines. Remove clutter_score_add():
the same functionality can be achieved by passing a NULL
parent to clutter_score_append().
* tests/test-score.c: Update ClutterScore test unit, and add
debug printouts.
* clutter/clutter-timeline.h:
* clutter/clutter-timeline.c
(timeline_timeout_func),
(clutter_timeline_get_delta): Add a function for retrieving
the number of frames and the time (in milliseconds) elapsed
since the last timeline ::new-frame signal. This can be useful
for implementing a physics engine or just for knowing how if
and how many frames have been skipped.
* clutter/clutter-effect.[ch]: Add clutter_effect_template_construct()
function, for language bindings that need to set the alpha function
but cannot call the clutter_effect_template_new() ctor themselves.
* clutter/cogl/cogl.h: Add cogl_fog_set() abstracting the
glFog() functions and enabling the GL_FOG flag.
* clutter/cogl/gl/cogl.c: Add GL implementation of cogl_fog_set().
* clutter/cogl/gles/cogl.c: Add GL/ES implementation of
cogl_fog_set().
* clutter.symbols: Add new symbols.
* clutter/clutter-stage.h: Add API to enable depth cueing on
the stage using a linear GL fog, and to set the parameters
for it (#637).
* clutter/clutter-stage.c (clutter_stage_paint): Enable the
GL fog if the ClutterStage:use-fog property is true.
* tests/test-depth.c: Test the new stage API.
* clutter/clutter-label.[ch]: Fix ClutterLabel size allocation when
no bounding box has been provided, and store the box set by the
user so that it can be reused when recomputing the layout. (#600)
(clutter_label_class_init),
(clutter_label_init): Set the :wrap property default to FALSE.
* clutter/clutter-units.h: Add ClutterUnit-to-PangoUnit conversion
macro.

* clutter.symbols: Update
* clutter/clutter-actor.h: Rename the angle argument for
set_rotationx() to avoid gtk-doc complaining

(clutter_get_motion_events_frequency),
(clutter_set_motion_events_frequency): Add accessors for the default
motion events deliver frequency.
