- * clutter_texture_new_from_actor:
- * @actor: A source #ClutterActor
- *
- * Creates a new #ClutterTexture object with its source a prexisting
- * actor (and associated children). The textures content will contain
- * 'live' redirected output of the actors scene.
- *
- * Note this function is intented as a utility call for uniformly applying
- * shaders to groups and other potential visual effects. It requires that
- * the %CLUTTER_FEATURE_OFFSCREEN feature is supported by the current backend
- * and the target system.
- *
- * 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_texture_set_from_file()) will destroy the offscreen texture
- * data and end redirection.</para>
- * </listitem>
- * <listitem>
- * <para>cogl_texture_get_data() with the handle returned by
