+ * @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
- * 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.)
+ * #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.
