wayland: Use an event filter instead of the captured event signal

In order to see all Clutter events, Mutter was previously installing a
signal handler on the ‘captured-event’ signal on the stage and
additionally using a signal emission hook to cope with grabs. This
changes it to use the new clutter_event_add_filter API so that we can
avoid the signal emission hook hack.

- * @title: MetaCullable
- * @short_description: CPU culling operations for efficient drawing
- *
- * When we are painting a stack of 5-10 large actors, the standard
- * bottom-to-top method of drawing every actor results in a tremendous
- * amount of overdraw. If these actors are painting textures like
- * windows, it can easily max out the available memory bandwidth on a
- * low-end graphics chipset. It's even worse if window textures are
- * being accessed over the AGP bus.
- *
- * #MetaCullable is our solution. The basic technique applied here is to
- * do a pre-pass before painting where we walk each actor from top to bottom
- * and ask each actor to "cull itself out". We pass in a region it can copy
- * to clip its drawing to, and the actor can subtract its fully opaque pixels
- * so that actors underneath know not to draw there as well.

  * MetaWindowGroup:
  *
  * This class is a subclass of ClutterActor with special handling for
- * #MetaCullable when painting children. It uses code similar to
- * meta_cullable_cull_out_children(), but also has additional special
- * cases for the undirected window, and similar.
+ * MetaWindowActor/MetaBackgroundActor/MetaBackgroundGroup when painting
+ * children.
+ *
+ * When we are painting a stack of 5-10 maximized windows, the
+ * standard bottom-to-top method of drawing every actor results in a
+ * tremendous amount of overdraw and can easily max out the available
+ * memory bandwidth on a low-end graphics chipset. It's even worse if
+ * window textures are being accessed over the AGP bus.
+ *
+ * The basic technique applied here is to do a pre-pass before painting
+ * where we walk window from top to bottom and compute the visible area
+ * at each step by subtracting out the windows above it. The visible
+ * area is passed to MetaWindowActor which uses it to clip the portion of
+ * the window which drawn and avoid redrawing the shadow if it is completely
+ * obscured.
+ *
+ * A caveat is that this is ineffective if applications are using ARGB
+ * visuals, since we have no way of knowing whether a window obscures
+ * the windows behind it or not. Alternate approaches using the depth
+ * or stencil buffer rather than client side regions might be able to
+ * handle alpha windows, but the combination of glAlphaFunc and stenciling
+ * tends not to be efficient except on newer cards. (And on newer cards
+ * we have lots of memory and bandwidth.)
