-# Mutter
-
-Mutter is a Wayland display server and X11 window manager and compositor library.
-
-When used as a Wayland display server, it runs on top of KMS and libinput. It
-implements the compositor side of the Wayland core protocol as well as various
-protocol extensions. It also has functionality related to running X11
-applications using Xwayland.
-
-When used on top of Xorg it acts as a X11 window manager and compositing manager.
-
-It contains functionality related to, among other things, window management,
-window compositing, focus tracking, workspace management, keybindings and
-monitor configuration.
-
-Internally it uses a fork of Cogl, a hardware acceleration abstraction library
-used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a
-scene graph and user interface toolkit.
-
-Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and
-by  Gala, elementary OS's window manager. It can also be run standalone, using
-the  command "mutter", but just running plain mutter is only intended for
-debugging purposes.
-
-## Contributing
-
-To contribute, open merge requests at https://gitlab.gnome.org/GNOME/mutter.
-
-The coding style used is primarily the GNU flavor of the [GNOME coding
-style](https://developer.gnome.org/programming-guidelines/stable/c-coding-style.html.en)
-with some minor additions such as preferring `stdint.h` types over GLib
-fundamental types, and a soft 80 character line limit. However, in general,
-look at the file you're editing for inspiration.
-
-Commit messages should follow the [GNOME commit message
-guidelines](https://wiki.gnome.org/Git/CommitMessages). We require an URL
-to either an issue or a merge request in each commit.

-Cleaning ClutterText
-

-  * Removing unused ClutterText::text-changed callback
-
-2010-07-05 Alejandro Pi<50>eiro <apinheiro@igalia.com>
-
-Refactoring "window:create" and "window:destroy" emission code
-
-Previously "window:create" and "window:destroy" were emitted on
-CallyUtil. Although it works, and CallyUtil already have callbacks to
-stage_added/removed signals, I think that it is more tidy/clear to do
-that on CallyRoot:
-
-  * CallyRoot already has code to manage ClutterStage addition/removal
-
-  * In fact, we can see CallyRoot as the object exposing the a11y
-    information from ClutterStageManager, so it fits better here.
-
-  * CallyUtil callbacks these signals are related to key event
-    listeners (key snooper simulation). One of the main CallyUtil
-    responsabilities is managing event (connecting, emitting), so I
-    would prefer to not start to add/mix more functionalities here.
-
-Ideally it would be better to emit all CallyStage methods from
-CallyStage, but it is clear that "create" and "destroy" are more easy
-to emit from a external object.
-
-2010-06-25 Alejandro Pi<50>eiro <apinheiro@igalia.com>
-
-Cleaning clutter-actor
-
-Some cleaning changes:
-  * Using CallyActionFunc instead of ACTION_FUNC
-  * Removing a extra * on cally-actor-private macro documentation, to
-    avoid gtk-doc warnings
-  * Using g_strcmp0 instead of strcmp
-
-Changes to be applied on clutter (see CB#2097 and CB#2098), applied
-also here to maintain the sync. My intention is keep this developing line
-until the real integration, in order to make a final independent cally
-release.

-

-
-Added dummy padding for future vt expasion
-
-Added dummy padding on the different classes structures, to allow
-future expansion of virtual methods.
-
-I decided to add this on all the classes, although it would be
-really unlikely in some cases (ie, CallyGroup)
-
-2010-06-10 Alejandro Pi<50>eiro <apinheiro@igalia.com>
-
-Adding and emitting "window:xxx" methods on CallyStage
-
-Added some window related signals on CallyStage:
-
-  * window:activate and window:deactivate emitted from CallyStage
-  * window:create and window:destroy emitted from CallyUtil
-
-ClutterStage doesn't fulfill 100% the window concept, but some of
-these signals are important in order to identify the object which
-could emit global/key events.
-
-The current implementation is equivalent to GailWindow one, supposing
-CallyStage as the only window related window. This likely would change
-in any clutter-based toolkit implement a real Window object, so a more
-flexible procedure would be required. But we would solve problems step
-by step.
-
-BTW: as I explain here [1] I really think that the current way to
-implement "window:xxx" signals (not defined in ATK but expected from
-the a11y implementation toolkit) somewhat hacky and undocumented (you
-need to check at-spi2 idls to know that you require to emit this
-events)
-
-Related to bug CB#2147 (Orca doesn't speech out properly non
-printable chars on some environments), as solves this problem
-in a specific case.

-Avoiding clutter_stage_get_key_focus warning
-
-For any reason, in some cases, a clutter actor doesn't have a stage
-associated. We use the default one as fallback.

-
-Removing heuristics to decide CallyRectable/CallyTexture role
-
-Previously CallyRectangle and CallyTexture used some heuristics in
-order to decide the default role: ATK_ROLE_IMAGE or
-ATK_PUSH_BUTTON, as in practice most applications using these
-objects as buttons were not applying the proper role.

-As this is a hack, and a application responsibility, finally we

-Post-release version bump, after release 1.2.0
-
-I wrongly added the last commit on the 1.1 branch, when in fact it
-requires clutter 1.3.3, and on the README it is explained that
-cally versioning is tied to clutter versioning. In order to solve
-that a clutter-1.2 release branch is created, and bumped the version.
-
-This versioning tyding will be obsolete when the integration with
-clutter become a reality, but in the same way, this is the way to
-tidy this thinking in this integration.

-
-Use clutter_actor_get_accessible
-
-The method clutter_actor_get_accessible was added due work on
-bug 2070, and should be used to get the accessibility object,
-instead of atk_gobject_accessible_for_object
-
-This would allow to implement a11y support directly on
-any clutter based toolkit object (ie StLabel).

-Remove gail dependency

-Removed to avoid gdk/gtk dependency on cally.

-Part of bug CB#2072 solution
-
-2010-04-14 Alejandro Pi<50>eiro <apinheiro@igalia.com>
-
-Avoid gdk functions filling AtkKeyEventStruct
-
-Now when AtkKeyEventStruct is filled in order to emit any key event
-signal, it is not used any gdk function on the keyval or the
-string fields.
-
-event_string is filled with the printable character if possible, if
-not (Ctrl, Alt, etc) it is set as NULL.
-
-Now the AT should take care of that, at least until we define atk key
-event struct in a more agnostic way (not tied to gdk/gtk). See orca
-bug bgo#616206 as a example.
-
-Part of bug CB#2072 solution.

-Change "--with-dbus" option for "atk-bridge-dir" on examples
-
-The atk-adaptor in the dbus at-spi was renamed to atk-bridge due
-some apps hardcoding the name. So right now the only difference
-is the final directory.
-
-So the option was removed, and atk-bridge-dir added. This also allows
-to use the system atk-bridge or the compiled in any developing environment,
-so it is really more flexible.
-
-See the README (updated with this commit) for more information.

-Using clutter_threads_idle_add instead of the gdk one
-
-The idea is being as less gdk dependent as possible. Right now
-it is inviable to remove the dependency (gailutil and so on) but
-hypothetically, the ideal is remove this dependency in the future,
-and being "clutter pure".

-
-Try to apply the key modifiers to event->keyval like GDK does
-
-ClutterKeyEvent defines the keyval without taking into account the
-modifiers. GDK defines this keyval taking into account the modifiers.
-
-AtkKeyEventStruct expects the keyval in a GDK fashion, so a
-translation is required.
-
-This patch tries to do that using using
-gdk_keymap_translate_keyboard_state.
-
-This functions only works correctly if gtk has been initialized, so
-the fallback is create the AtkKeyEventStruct with the keyval
-provided by Clutter.

-
-Filling AtkKeyEventStruct->string used on the atk key event listeners

-Check on configure time if any x11 clutter backend is in use
-
-It uses AC_CHECK_LIB in order to check if x11 backend is in use.
-It also modifies cally-actor in order to use the information
-retrieved.
-
-So now cally has a minimum multi-backend support. It only manages
-a x11 (glx or eglx) backend, but at least, it checks it, so you
-can compile cally without this backend. It probably will not work
-properly, but at least you can compile and execute it.

-* configure.ac:
-  Change API_VERSION_MAJOR for CALLY_API_VERSION, as was the real
-  meaning, and define CALLY_VERSION.
-  Change CALLY_OBJ_CFLAGS and CALLY_OBJ_LIBS, used to compile the
-  tests, as was not required to compile against the cally module (the
-  example only required to compile against Clutter, as the cally
-  module was just a module loaded by GModule).
-  Support for Shave.

-
-Be able to run the examples without installing Cally
-
-Before that, the examples searched the cally module from the final installed
-directory. This means that you should install the library to use the examples.
-On development this is not desirable. Now it is loaded from ../cally/.libs
-
-This is a little hackish, but more useful, and in the end, it is just a example.
-Probably a best option could be configure that on the command line.
-   $ ./example --cally-dir="mydir"

-But just a nitpick.

-2009-06-30 Alejandro Pi<50>eiro <apinheiro@igalia.com>
-
-Added the implementation of most AtkText methods for CluttetText (CallyText)
-
-It remains some methods:
-  get_default_attributes
-  get_character_extents
-  get_offset_at_point
-
-The current gail implementation delegate on gailmisc, but this is tied to
-GtkWidget so an equivalent functionality would be implemented (something like
-callymisc), and in the case of get_character_extents, not sure about the layout
-position (see gtk_entry_get_layout_offsets).
-
-I think that worth manage this in a different commit.
-
-In the same way is still missing AtkEditableText support.

-2009-07-07 Alejandro Pi<50>eiro <apinheiro@igalia.com>
-
-Added CALLY_GET_CLUTTER_ACTOR macro
-
-This macro was created to simplify how do you get the clutter actor object
-related to the cally object. On CallyActor a private attributte maintains it
-(for convenience, as it is heavily used) but outside, atkgobject methods can
-be used. Note that there is a possibility on the future to change it. Two
-options:
-  * Add a public method to get the clutter object
-  * Use this method on CallyActor too
-
-This macro simplifies this:
-
-CLUTTER_ACTOR (atk_gobject_accessible_get_object (ATK_GOBJECT_ACCESSIBLE (cally_object)))

-	* cail/cail-actor.c
-	(cail_actor_connect_actor_destroyed): connects to the clutter actor
-	destroy signal
-	(cail_actor_clutter_actor_destroyed): handler to the clutter actor
-	destroy signal, update the priv->actor pointer and notify a state change
-
-	This change allows to be sure about the priv->actor correct value, so we
-	can use directly priv->actor instead of atk_gobject_accessible_get_object
-	in the next functions:
-	(cail_actor_get_parent)

- * @see_also: #ClutterClone
- *
- * #CallyClone implements the required ATK interfaces of #ClutterClone
- *
- * In particular it sets a proper role for the clone, as just a image,
- * as it is the sanest and simplest approach.
- */
-
-/* Design rationale for CallyClone:
- *
- * In the old times, it was just ClutterCloneTexture. So, from a a11y POV
- * CallyCloneTexture was just another image, like ClutterTexture, and if
- * it was a clone was irrevelant. So on cally-0.8, CallyCloneTexture
- * expose a object with role ATK_ROLE_IMAGE. But now, ClutterClone is more
- * general. You can clone any object, including groups, and made things
- * like have one text entry, and a clone with different properties in the
- * same window, updated both at once.
- *
- * The question is if the idea is have a ClutterClone as a "first-class"
- * citizen inside the stage hierarchy (full clone), or it is just supposed
- * to be a mirror image of the original object.
- *
- * In the case of the a11y POV this would mean that if the text changes on
- * the source, the clone should emit as well the text-changing signals.
- *
- * As ClutterClone smartly just paint the same object with different
- * parameters, this would mean that it should be the cally object the one
- * that should replicate the source clutter hierarchy to do that,
- * something that just sound crazy.
- *
- * Taking into account that:
- *
- * - ClutterClone doesn't re-emit mirrored signals from the source 
- *   I think that likely the answer would be "yes, it is just a
- *   mirrored image, not a real full clone".
- *
- * - You can't interact directly with the clone (ie: focus, and so on).
- *   Its basic usage (right now) is clone textures.
- *
- * Any other solution could be overwhelming.
- *
- * I think that the final solution would be that ClutterClone from the
- * a11y POV should still be managed as a image (with the proper properties,
- * position, size, etc.).

- * #ClutterBinLayout is a layout manager which implements the following
- * policy:
- *
- *   - the preferred size is the maximum preferred size
- *   between all the children of the container using the
- *   layout;
- *   - each child is allocated in "layers", on on top
- *   of the other;
- *   - for each layer there are horizontal and vertical
- *   alignment policies.
- *
- * The [bin-layout example](https://git.gnome.org/browse/clutter/tree/examples/bin-layout.c?h=clutter-1.18)
- * shows how to pack actors inside a #ClutterBinLayout.

- * SECTION:clutter-bind-constraint
- * @Title: ClutterBindConstraint
- * @Short_Description: A constraint binding the position or size of an actor
- *
- * #ClutterBindConstraint is a #ClutterConstraint that binds the
- * position or the size of the #ClutterActor to which it is applied
- * to the the position or the size of another #ClutterActor, or
- * "source".
- *
- * An offset can be applied to the constraint, to avoid overlapping. The offset
- * can also be animated. For instance, the following code will set up three
- * actors to be bound to the same origin:
- *
- * |[<!-- language="C" -->
- * // source
- * rect[0] = clutter_rectangle_new_with_color (&red_color);
- * clutter_actor_set_position (rect[0], x_pos, y_pos);
- * clutter_actor_set_size (rect[0], 100, 100);
- *
- * // second rectangle
- * rect[1] = clutter_rectangle_new_with_color (&green_color);
- * clutter_actor_set_size (rect[1], 100, 100);
- * clutter_actor_set_opacity (rect[1], 0);
- *
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_X, 0.0);
- * clutter_actor_add_constraint_with_name (rect[1], "green-x", constraint);
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_Y, 0.0);
- * clutter_actor_add_constraint_with_name (rect[1], "green-y", constraint);
- *
- * // third rectangle
- * rect[2] = clutter_rectangle_new_with_color (&blue_color);
- * clutter_actor_set_size (rect[2], 100, 100);
- * clutter_actor_set_opacity (rect[2], 0);
- *
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_X, 0.0);
- * clutter_actor_add_constraint_with_name (rect[2], "blue-x", constraint);
- * constraint = clutter_bind_constraint_new (rect[0], CLUTTER_BIND_Y, 0.0);
- * clutter_actor_add_constraint_with_name (rect[2], "blue-y", constraint);
- * ]|
- *
- * The following code animates the second and third rectangles to "expand"
- * them horizontally from underneath the first rectangle:
- *
- * |[<!-- language="C" -->
- * clutter_actor_animate (rect[1], CLUTTER_EASE_OUT_CUBIC, 250,
- *                        "@constraints.green-x.offset", 100.0,
- *                        "opacity", 255,
- *                        NULL);
- * clutter_actor_animate (rect[2], CLUTTER_EASE_OUT_CUBIC, 250,
- *                        "@constraints.blue-x.offset", 200.0,
- *                        "opacity", 255,
- *                        NULL);
- * ]|
- *

-/**
- * SECTION:clutter-binding-pool
- * @short_description: Pool for key bindings
- *
- * #ClutterBindingPool is a data structure holding a set of key bindings.
- * Each key binding associates a key symbol (eventually with modifiers)
- * to an action. A callback function is associated to each action.
- *
- * For a given key symbol and modifier mask combination there can be only one
- * action; for each action there can be only one callback. There can be
- * multiple actions with the same name, and the same callback can be used
- * to handle multiple key bindings.
- *
- * Actors requiring key bindings should create a new #ClutterBindingPool
- * inside their class initialization function and then install actions
- * like this:
- *
- * |[<!-- language="C" -->
- * static void
- * foo_class_init (FooClass *klass)
- * {
- *   ClutterBindingPool *binding_pool;
- *
- *   binding_pool = clutter_binding_pool_get_for_class (klass);
- *
- *   clutter_binding_pool_install_action (binding_pool, "move-up",
- *                                        CLUTTER_Up, 0,
- *                                        G_CALLBACK (foo_action_move_up),
- *                                        NULL, NULL);
- *   clutter_binding_pool_install_action (binding_pool, "move-up",
- *                                        CLUTTER_KP_Up, 0,
- *                                        G_CALLBACK (foo_action_move_up),
- *                                        NULL, NULL);
- * }
- * ]|
- *
- * The callback has a signature of:
- *
- * |[<!-- language="C" -->
- *    gboolean (* callback) (GObject             *instance,
- *                           const gchar         *action_name,
- *                           guint                key_val,
- *                           ClutterModifierType  modifiers,
- *                           gpointer             user_data);
- * ]|
- *
- * The actor should then override the #ClutterActor::key-press-event and
- * use clutter_binding_pool_activate() to match a #ClutterKeyEvent structure
- * to one of the actions:
- *
- * |[<!-- language="C" -->
- *   ClutterBindingPool *pool;
- *
- *   // retrieve the binding pool for the type of the actor
- *   pool = clutter_binding_pool_find (G_OBJECT_TYPE_NAME (actor));
- *
- *   // activate any callback matching the key symbol and modifiers
- *   // mask of the key event. the returned value can be directly
- *   // used to signal that the actor has handled the event.
- *   return clutter_binding_pool_activate (pool,
- *                                         key_event->keyval,
- *                                         key_event->modifier_state,
- *                                         G_OBJECT (actor));
- * ]|
- *
- * The clutter_binding_pool_activate() function will return %FALSE if
- * no action for the given key binding was found, if the action was
- * blocked (using clutter_binding_pool_block_action()) or if the
- * key binding handler returned %FALSE.
- *
- * #ClutterBindingPool is available since Clutter 1.0

-/**
- * ClutterChildMeta:
- * @container: the container handling this data
- * @actor: the actor wrapped by this data
- * 
- * Base interface for container specific state for child actors. A child
- * data is meant to be used when you need to keep track of information
- * about each individual child added to a container.
- *
- * In order to use it you should create your own subclass of
- * #ClutterChildMeta and set the #ClutterContainerIface child_meta_type
- * interface member to your subclass type, like:
- *
- * |[
- * static void
- * my_container_iface_init (ClutterContainerIface *iface)
- * {
- *   // set the rest of the #ClutterContainer vtable
- *
- *   container_iface->child_meta_type  = MY_TYPE_CHILD_META;
- * }
- * ]|
- *
- * This will automatically create a #ClutterChildMeta of type
- * `MY_TYPE_CHILD_META` for every actor that is added to the container.
- *
- * The child data for an actor can be retrieved using the
- * clutter_container_get_child_meta() function.
- * 
- * The properties of the data and your subclass can be manipulated with
- * clutter_container_child_set() and clutter_container_child_get() which
- * act like g_object_set() and g_object_get().
- *
- * You can provide hooks for your own storage as well as control the
- * instantiation by overriding the #ClutterContainerIface virtual functions
- * #ClutterContainerIface.create_child_meta(), #ClutterContainerIface.destroy_child_meta(),
- * and #ClutterContainerIface.get_child_meta().

-/**
- * SECTION:clutter-click-action
- * @Title: ClutterClickAction
- * @Short_Description: Action for clickable actors
- *
- * #ClutterClickAction is a sub-class of #ClutterAction that implements
- * the logic for clickable actors, by using the low level events of
- * #ClutterActor, such as #ClutterActor::button-press-event and
- * #ClutterActor::button-release-event, to synthesize the high level
- * #ClutterClickAction::clicked signal.
- *
- * To use #ClutterClickAction you just need to apply it to a #ClutterActor
- * using clutter_actor_add_action() and connect to the
- * #ClutterClickAction::clicked signal:
- *
- * |[
- *   ClutterAction *action = clutter_click_action_new ();
- *
- *   clutter_actor_add_action (actor, action);
- *
- *   g_signal_connect (action, "clicked", G_CALLBACK (on_clicked), NULL);
- * ]|
- *
- * #ClutterClickAction also supports long press gestures: a long press is
- * activated if the pointer remains pressed within a certain threshold (as
- * defined by the #ClutterClickAction:long-press-threshold property) for a
- * minimum amount of time (as the defined by the
- * #ClutterClickAction:long-press-duration property).
- * The #ClutterClickAction::long-press signal is emitted multiple times,
- * using different #ClutterLongPressState values; to handle long presses
- * you should connect to the #ClutterClickAction::long-press signal and
- * handle the different states:
- *
- * |[
- *   static gboolean
- *   on_long_press (ClutterClickAction    *action,
- *                  ClutterActor          *actor,
- *                  ClutterLongPressState  state)
- *   {
- *     switch (state)
- *       {
- *       case CLUTTER_LONG_PRESS_QUERY:
- *         /&ast; return TRUE if the actor should support long press
- *          &ast; gestures, and FALSE otherwise; this state will be
- *          &ast; emitted on button presses
- *          &ast;/
- *         return TRUE;
- *
- *       case CLUTTER_LONG_PRESS_ACTIVATE:
- *         /&ast; this state is emitted if the minimum duration has
- *          &ast; been reached without the gesture being cancelled.
- *          &ast; the return value is not used
- *          &ast;/
- *         return TRUE;
- *
- *       case CLUTTER_LONG_PRESS_CANCEL:
- *         /&ast; this state is emitted if the long press was cancelled;
- *          &ast; for instance, the pointer went outside the actor or the
- *          &ast; allowed threshold, or the button was released before
- *          &ast; the minimum duration was reached. the return value is
- *          &ast; not used
- *          &ast;/

-/**
- * SECTION:clutter-constraint
- * @Title: ClutterConstraint
- * @Short_Description: Abstract class for constraints on position or size
- * @See_Also: #ClutterAction
- *
- * #ClutterConstraint is a base abstract class for modifiers of a #ClutterActor
- * position or size.
- *
- * A #ClutterConstraint sub-class should contain the logic for modifying
- * the position or size of the #ClutterActor to which it is applied, by
- * updating the actor's allocation. Each #ClutterConstraint can change the
- * allocation of the actor to which they are applied by overriding the
- * #ClutterConstraintClass.update_allocation() virtual function.
- *
- * #ClutterConstraint is available since Clutter 1.4
- *
- * ## Using Constraints
- *
- * Constraints can be used with fixed layout managers, like
- * #ClutterFixedLayout, or with actors implicitly using a fixed layout
- * manager, like #ClutterGroup and #ClutterStage.
- *
- * Constraints provide a way to build user interfaces by using
- * relations between #ClutterActors, without explicit fixed
- * positioning and sizing, similarly to how fluid layout managers like
- * #ClutterBoxLayout lay out their children.
- *
- * Constraints are attached to a #ClutterActor, and are available
- * for inspection using clutter_actor_get_constraints().
- *
- * Clutter provides different implementation of the #ClutterConstraint
- * abstract class, for instance:
- *
- *  - #ClutterAlignConstraint, a constraint that can be used to align
- *  an actor to another one on either the horizontal or the vertical
- *  axis, using a normalized value between 0 and 1.
- *  - #ClutterBindConstraint, a constraint binds the X, Y, width or height
- *  of an actor to the corresponding position or size of a source actor,
- *  with or without an offset.
- *  - #ClutterSnapConstraint, a constraint that "snaps" together the edges
- *  of two #ClutterActors; if an actor uses two constraints on both its
- *  horizontal or vertical edges then it can also expand to fit the empty
- *  space.
- *
- * The [constraints example](https://git.gnome.org/browse/clutter/tree/examples/constraints.c?h=clutter-1.18)
- * uses various types of #ClutterConstraints to lay out three actors on a
- * resizable stage. Only the central actor has an explicit size, and no
- * actor has an explicit position.
- *
- *  - The #ClutterActor with #ClutterActor:name `layerA` is explicitly
- *  sized to 100 pixels by 25 pixels, and it's added to the #ClutterStage
- *  - two #ClutterAlignConstraints are used to anchor `layerA` to the
- *  center of the stage, by using 0.5 as the alignment #ClutterAlignConstraint:factor on
- *  both the X and Y axis
- *  - the #ClutterActor with #ClutterActor:name `layerB` is added to the
- *  #ClutterStage with no explicit size
- *  - the #ClutterActor:x and #ClutterActor:width of `layerB` are bound
- *  to the same properties of `layerA` using two #ClutterBindConstraint
- *  objects, thus keeping `layerB` aligned to `layerA`
- *  - the top edge of `layerB` is snapped together with the bottom edge
- *  of `layerA`; the bottom edge of `layerB` is also snapped together with
- *  the bottom edge of the #ClutterStage; an offset is  given to the two
- *  #ClutterSnapConstraintss to allow for some padding; since `layerB` is
- *  snapped between two different #ClutterActors, its height is stretched
- *  to match the gap
- *  - the #ClutterActor with #ClutterActor:name `layerC` mirrors `layerB`,
- *  snapping the top edge of the #ClutterStage to the top edge of `layerC`
- *  and the top edge of `layerA` to the bottom edge of `layerC`
- *
- * You can try resizing interactively the #ClutterStage and verify
- * that the three #ClutterActors maintain the same position and
- * size relative to each other, and to the #ClutterStage.
- *
- * It is important to note that Clutter does not avoid loops or
- * competing constraints; if two or more #ClutterConstraints
- * are operating on the same positional or dimensional attributes of an
- * actor, or if the constraints on two different actors depend on each
- * other, then the behavior is undefined.
- *
- * ## Implementing a ClutterConstraint
- *
- * Creating a sub-class of #ClutterConstraint requires the
- * implementation of the #ClutterConstraintClass.update_allocation()
- * virtual function.
- *
- * The `update_allocation()` virtual function is called during the
- * allocation sequence of a #ClutterActor, and allows any #ClutterConstraint
- * attached to that actor to modify the allocation before it is passed to
- * the actor's #ClutterActorClass.allocate() implementation.
- *
- * The #ClutterActorBox passed to the `update_allocation()` implementation
- * contains the original allocation of the #ClutterActor, plus the eventual
- * modifications applied by the other #ClutterConstraints, in the same order
- * the constraints have been applied to the actor.
- *
- * It is not necessary for a #ClutterConstraint sub-class to chain
- * up to the parent's implementation.
- *
- * If a #ClutterConstraint is parametrized - i.e. if it contains
- * properties that affect the way the constraint is implemented - it should
- * call clutter_actor_queue_relayout() on the actor to which it is attached
- * to whenever any parameter is changed. The actor to which it is attached
- * can be recovered at any point using clutter_actor_meta_get_actor().

- * SECTION:clutter-deform-effect
- * @Title: ClutterDeformEffect
- * @Short_Description: A base class for effects deforming the geometry
- *   of an actor
- *
- * #ClutterDeformEffect is an abstract class providing all the plumbing
- * for creating effects that result in the deformation of an actor's
- * geometry.
- *
- * #ClutterDeformEffect uses offscreen buffers to render the contents of
- * a #ClutterActor and then the Cogl vertex buffers API to submit the
- * geometry to the GPU.
- *
- * #ClutterDeformEffect is available since Clutter 1.4
- *
- * ## Implementing ClutterDeformEffect
- *
- * Sub-classes of #ClutterDeformEffect should override the
- * #ClutterDeformEffectClass.deform_vertex() virtual function; this function
- * is called on every vertex that needs to be deformed by the effect.
- * Each passed vertex is an in-out parameter that initially contains the
- * position of the vertex and should be modified according to a specific
- * deformation algorithm.
