Reduce overpaint in the window group 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. When we have opaque windows, we can go ahead and compute visibility ourselves (in classic X-server fashion) and use that information to restrict drawing obscured actors. * Add MutterWindowGroup - a ClutterGroup subclass with logic for figuring out obscured regions. * Add mutter_window_get_obscured_region() to get the region obscured by that window. * Add mutter_shaped_texture_set_clip_region() to hint a clip region to the painting code; this is set based on the computed visible region of MutterWindowGroup. * Add tidy_texture_frame_set_needs_paint() to hint that the paint can be skipped entirely; this is used when we detect that the window shadow is entirely obscured. http://bugzilla.gnome.org/show_bug.cgi?id=587344

Simplify relationship between mapping and visibility Previously, changes to the visibility of a window could be indicated by meta_compositor_map_window(), meta_compositor_unminimize_window(), meta_compositor_set_window_hidden(), etc, with the exact behavior depending on the 'live_hidden_windows' preference. Simplify this so that visibility is controlled by: meta_compositor_show_window() meta_compositor_hide_window() With an 'effect' parameter provided to indicate the appropriate effect (CREATE/UNMINIMIZE/MINIMIZE/DESTROY/NONE.) The map state of the window is signalled separately by: meta_compositor_map_window() meta_compositor_unmap_window() And is used only to control resource handling. Other changes: * The desired effect on show/hide is explicitly stored in MetaWindow, avoiding the need for the was_minimized flag. At idle, once we calculate the window state, we pass the effect to the compositor if it matches the new window state, and then clear the effect to start over for future map state changes. * meta_compositor_switch_workspace() is called before any windows are hidden or shown, allowing the compositor to avoid hiding or showing an effect for windows involved in the switch. http://bugzilla.gnome.org/show_bug.cgi?id=582341 * Handling of post-effect cleanups for MutterWindow are simplified - instead of trying to do different things based on the individual needs of different effects, we just wait until all effects complete and sync the window state to what it should be. * On unmap, once we destroy the pixmap, we tell ClutterX11Pixmap that we've done so, so it can clean up and unbind. (The unbinding doesn't seem to be working properly because of ClutterGLXPixmap or video driver issues.) http://bugzilla.gnome.org/show_bug.cgi?id=587251

Move window repair and reshape to a paint function Add a paint function that checks all windows for repair and shape updates; this: - simplifies the logic for when a window needs to be repaired - avoids duplicate work when we get multiple damage effects - avoids the need to look ahead in the event queue Instead of relying on repair to implicitly resize the MutterWindow actor, set the size explicitly when the core code updates the geometry. (This is needed because we haven't repaired yet when we start an animation, and the animation may depend on the size to, e.g., rescale from the center.) Because the core geometry update happens before we start maximize/unmaximize effects we need to work around this by passing both the old and new geometry to the compositor. http://bugzilla.gnome.org/show_bug.cgi?id=587251
