- * @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.

- * meta_cullable_cull_out:
- * @cullable: The #MetaCullable
- * @unobscured_region: The unobscured region, in @cullable's space.
- * @clip_region: The clip region, in @cullable's space.
- *
- * When #MetaWindowGroup is painted, we walk over its direct cullable
- * children from top to bottom and ask themselves to "cull out". Cullables
- * can use @unobscured_region and @clip_region to clip their drawing. Actors
- * interested in eliminating overdraw should copy the @clip_region and only
- * paint those parts, as everything else has been obscured by actors above it.
- *
- * Actors that may have fully opaque parts should also subtract out a region
- * that is fully opaque from @unobscured_region and @clip_region.
- *
- * @unobscured_region and @clip_region are extremely similar. The difference
- * is that @clip_region starts off with the stage's clip, if Clutter detects
- * that we're doing a clipped redraw. @unobscured_region, however, starts off
- * with the full stage size, so actors that may want to record what parts of
- * their window are unobscured for e.g. scheduling repaints can do so.
- *
- * Actors that have children can also use the meta_cullable_cull_out_children()
- * helper method to do a simple cull across all their children.

  * 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.)
