window: Assume CSD frame extents are 0 in maximized and tiling modes

When the user maximized a CSD window, this is the order of operations
that happens:

  1. The CSD application sends us a _NET_WM_STATE client message telling
     us to add the _NET_WM_MAXIMIZED_VERT/HORZ state.

  2. We respond by setting _NET_WM_STATE on the window and resizing the
     window. Windows are positioned according to the visible borders of
     the window, so since _GTK_FRAME_EXTENTS has not been updated yet to
     reflect the border/padding of the window state, the borders are wrong.

  3. GTK+ gets the _NET_WM_STATE event, updates its state, and then sets
     new theme properties, including _GTK_FRAME_EXTENTS.

  4. mutter sees that _GTK_FRAME_EXTENTS has been updated, and repositions
     the window to where it should be.

This means that the user sees the borders "flicker" for a half-second while
the maximization state is in limbo. Trying to make this resize operation
atomic is a foregone conclusion under X11, so to solve this, we're going to
make two changes to our _GTK_FRAME_EXTENTS protocol:

  1. _GTK_FRAME_EXTENTS now reflects the "normal" borders, always. This
     means that _GTK_FRAME_EXTENTS should not change at runtime unless the
     theme changes.

  2. mutter will only respect _GTK_FRAME_EXTENTS in places where the user
     expects to see a shadow. This means that mutter will hardcode the
     extents to 0 when the window is maximized. If the window is tiled-left,
     then all extents will be 0, except for the shadow on the right hand
     side, and vice versa for the tiled-right state.

+ * @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
- * 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
