-Poll the bus for messages. Will block while waiting for messages to come.
-You can specify a maximum time to poll with the @timeout parameter. If
-All messages not in @events will be popped off the bus and will be ignored.
-Because poll is implemented using the "message" signal enabled by
-gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
-signal to be emitted for every message that poll sees. Thus a "message"
-signal handler will see the same messages that this function sees -- neither
-will steal messages from the other.
-This function will run a main loop from the default main context when

-You should never use this function, since it is pure evil. This is
-especially true for GUI applications based on Gtk+ or Qt, but also for any
-other non-trivial application that uses the GLib main loop. As this function
-runs a GLib main loop, any callback attached to the default GLib main
-context may be invoked. This could be timeouts, GUI events, I/O events etc.;
-even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
-may do things you do not expect, e.g. destroy the main application window or
-some other resource; change other application state; display a dialog and
-run another main loop until the user clicks it away. In short, using this
-function may add a lot of complexity to your code through unexpected
-re-entrancy and unexpected changes to your application's state.
-For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
-other short timeouts use gst_bus_timed_pop_filtered(); everything else is
-better handled by setting up an asynchronous bus watch and doing things
-from there.

+For example, this:
+|[
+clutter_actor_animate (rectangle, CLUTTER_LINEAR, 250,
+"width", 100.0,
+"height", 100.0,
+NULL);
+]|
+will make width and height properties of the #ClutterActor "rectangle"
+grow linearly between the current value and 100 pixels, in 250 milliseconds.
+The animation @mode is a logical id, either from the #ClutterAnimationMode
+enumeration of from clutter_alpha_register_func().
+All the properties specified will be animated between the current value
+and the final value. If a property should be set at the beginning of
+the animation but not updated during the animation, it should be prefixed
+by the "fixed::" string, for instance:
+|[
+clutter_actor_animate (actor, CLUTTER_EASE_IN_SINE, 100,
+"rotation-angle-z", 360.0,
+"fixed::rotation-center-z", &amp;center,
+NULL);
+]|
+Will animate the "rotation-angle-z" property between the current value
+and 360 degrees, and set the "rotation-center-z" property to the fixed
+value of the #ClutterVertex "center".
+This function will implicitly create a #ClutterAnimation object which
+will be assigned to the @actor and will be returned to the developer
+to control the animation or to know when the animation has been
+completed.
+If a name argument starts with "signal::", "signal-after::",
+"signal-swapped::" or "signal-swapped-after::" the two following arguments
+are used as callback function and data for a signal handler installed on
+the #ClutterAnimation object for the specified signal name, for instance:
+|[
+static void
+on_animation_completed (ClutterAnimation *animation,
+ClutterActor *actor)
+{
+clutter_actor_hide (actor);
+}
+clutter_actor_animate (actor, CLUTTER_EASE_IN_CUBIC, 100,
+"opacity", 0,
+"signal::completed", on_animation_completed, actor,
+NULL);
+]|
+or, to automatically destroy an actor at the end of the animation:
+|[
+clutter_actor_animate (actor, CLUTTER_EASE_IN_CUBIC, 100,
+"opacity", 0,
+"signal-swapped-after::completed",
+clutter_actor_destroy,
+actor,
+NULL);
+]|
+The "signal::" modifier is the equivalent of using g_signal_connect();
+the "signal-after::" modifier is the equivalent of using
+g_signal_connect_after() or g_signal_connect_data() with the
+%G_CONNECT_AFTER; the "signal-swapped::" modifier is the equivalent
+of using g_signal_connect_swapped() or g_signal_connect_data() with the
+%G_CONNECT_SWAPPED flah; finally, the "signal-swapped-after::" modifier
+is the equivalent of using g_signal_connect_data() with both the
+%G_CONNECT_AFTER and %G_CONNECT_SWAPPED flags. The clutter_actor_animate()
+function will not keep track of multiple connections to the same signal,
+so it is your responsability to avoid them when calling
+clutter_actor_animate() multiple times on the same actor.
+Calling this function on an actor that is already being animated
+will cause the current animation to change with the new final values,
+the new easing mode and the new duration - that is, this code:
+|[
+clutter_actor_animate (actor, CLUTTER_LINEAR, 250,
+"width", 100.0,
+"height", 100.0,
+NULL);
+clutter_actor_animate (actor, CLUTTER_EASE_IN_CUBIC, 500,
+"x", 100.0,
+"y", 100.0,
+"width", 200.0,
+NULL);
+]|
+is the equivalent of:
+|[
+clutter_actor_animate (actor, CLUTTER_EASE_IN_CUBIC, 500,
+"x", 100.0,
+"y", 100.0,
+"width", 200.0,
+"height", 100.0,
+NULL);
+]|
+<note>Unless the animation is looping, the #ClutterAnimation created by
+clutter_actor_animate() will become invalid as soon as it is
+complete.</note>
+Since the created #ClutterAnimation instance attached to @actor
+is guaranteed to be valid throughout the #ClutterAnimation::completed
+signal emission chain, you will not be able to create a new animation
+using clutter_actor_animate() on the same @actor from within the
+#ClutterAnimation::completed signal handler unless you use
+g_signal_connect_after() to connect the callback function, for instance:
+|[

+for integration with embedding toolkits, like clutter-gtk
+Embedding toolkits that disable the event collection inside Clutter
+need to use this function to update the state of input devices depending
+on a #ClutterEvent that they are going to submit to the event handling code
+in Clutter though clutter_do_event(). Since the input devices hold the state
+that is going to be used to fill in fields like the #ClutterButtonEvent
+click count, or to emit synthesized events like %CLUTTER_ENTER and
+%CLUTTER_LEAVE, it is necessary for embedding toolkits to also be
+responsible of updating the input device state.
+For instance, this might be the code to translate an embedding toolkit
+native motion notification into a Clutter #ClutterMotionEvent and ask
+Clutter to process it:
+|[
+ClutterEvent c_event;
+translate_native_event_to_clutter (native_event, &amp;c_event);
+clutter_do_event (&amp;c_event);

+Some tips on usage:
+<itemizedlist>
+<listitem>
+<para>The source actor must be made visible (i.e by calling
+#clutter_actor_show).</para>
+</listitem>
+<listitem>
+<para>The source actor must have a parent in order for it to be
+allocated a size from the layouting mechanism. If the source
+actor does not have a parent when this function is called then
+the ClutterTexture will adopt it and allocate it at its
+preferred size. Using this you can clone an actor that is
+otherwise not displayed. Because of this feature if you do
+intend to display the source actor then you must make sure that
+the actor is parented before calling
+clutter_texture_new_from_actor() or that you unparent it before
+adding it to a container.</para>
+</listitem>
+<listitem>
+<para>When getting the image for the clone texture, Clutter
+will attempt to render the source actor exactly as it would
+appear if it was rendered on screen. The source actor's parent
+transformations are taken into account. Therefore if your
+source actor is rotated along the X or Y axes so that it has
+some depth, the texture will appear differently depending on
+the on-screen location of the source actor. While painting the
+source actor, Clutter will set up a temporary asymmetric
+perspective matrix as the projection matrix so that the source
+actor will be projected as if a small section of the screen was
+being viewed. Before version 0.8.2, an orthogonal identity
+projection was used which meant that the source actor would be
+clipped if any part of it was not on the zero Z-plane.</para>
+</listitem>
+<listitem>
+<para>Avoid reparenting the source with the created texture.</para>
+</listitem>
+<listitem>
+<para>A group can be padded with a transparent rectangle as to
+provide a border to contents for shader output (blurring text
+for example).</para>
+</listitem>
+<listitem>
+<para>The texture will automatically resize to contain a further
+transformed source. However, this involves overhead and can be
+avoided by placing the source actor in a bounding group
+sized large enough to contain any child tranformations.</para>
+</listitem>
+<listitem>
+<para>Uploading pixel data to the texture (e.g by using
+clutter_actor_set_from_file()) will destroy the offscreen texture data

+- setup some OpenGL state.
+- draw using OpenGL (e.g. glDrawArrays() )

+- setup some OpenGL state.
+- use Cogl to draw
+- reset modified OpenGL state.

+When the internals of Cogl evolves, this is very liable to break.
+This function will flush all batched primitives, and subsequently flush
+all internal Cogl state to OpenGL as if it were going to draw something
+itself.
+The result is that the OpenGL modelview matrix will be setup; the state
+corresponding to the current source material will be set up and other world
+state such as backface culling, depth and fogging enabledness will be sent
+to OpenGL.
+<note>No special material state is flushed, so if you want Cogl to setup a
+simplified material state it is your responsibility to set a simple source
+material before calling cogl_begin_gl(). E.g. by calling
+cogl_set_source_color4ub().</note>
+<note>It is your responsibility to restore any OpenGL state that you modify
+to how it was after calling cogl_begin_gl() if you don't do this then the
+result of further Cogl calls is undefined.</note>
+<note>You can not nest begin/end blocks.</note>

+possible we would prefer to improve Cogl than have developers require raw

+This provides no guarantees about the GL state upon returning and to avoid

+Poll the bus for messages. Will block while waiting for messages to come.
+You can specify a maximum time to poll with the @timeout parameter. If
+All messages not in @events will be popped off the bus and will be ignored.
+Because poll is implemented using the "message" signal enabled by
+gst_bus_add_signal_watch(), calling gst_bus_poll() will cause the "message"
+signal to be emitted for every message that poll sees. Thus a "message"
+signal handler will see the same messages that this function sees -- neither
+will steal messages from the other.
+This function will run a main loop from the default main context when
+polling.
+You should never use this function, since it is pure evil. This is
+especially true for GUI applications based on Gtk+ or Qt, but also for any
+other non-trivial application that uses the GLib main loop. As this function
+runs a GLib main loop, any callback attached to the default GLib main
+context may be invoked. This could be timeouts, GUI events, I/O events etc.;
+even if gst_bus_poll() is called with a 0 timeout. Any of these callbacks
+may do things you do not expect, e.g. destroy the main application window or
+some other resource; change other application state; display a dialog and
+run another main loop until the user clicks it away. In short, using this
+function may add a lot of complexity to your code through unexpected
+re-entrancy and unexpected changes to your application's state.
+For 0 timeouts use gst_bus_pop_filtered() instead of this function; for
+other short timeouts use gst_bus_timed_pop_filtered(); everything else is
+better handled by setting up an asynchronous bus watch and doing things
+from there.

+In GStreamer, image tags are #GstBuffer<!-- -->s containing the raw image
