- * SECTION:meta-cullable
- * @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.)

Author	SHA1	Message	Date
Jasper St. Pierre	531a7b2812	wayland: Support alternative focus modes like focus-follows-mouse Use the existing code for MetaWindow focus-follows-mouse to support this.	2013-11-02 12:53:32 -04:00
Jasper St. Pierre	580669cdea	display: Use MetaWindow for auto-raise callbacks This allows us to autoraise Wayland windows... well, except for the XQueryPointer, but we'll replace that soon.	2013-11-02 12:53:31 -04:00

Jasper St. Pierre	997188e914	wayland: Drop focus on click The native raise-on-click works with Wayland clients through the standard Grand Central Station event handling, with MetaWindow.	2013-11-02 12:53:31 -04:00
Jasper St. Pierre	c6dd56f9ce	wayland: Drop old hack to synthesize motion events mutter now uses Clutter events for the source of its drag support, so we don't need to synthesize X11 events anymore.	2013-11-02 12:53:31 -04:00
Jasper St. Pierre	466af03ed3	keybindings: Port to Clutter	2013-11-02 12:53:31 -04:00
Neil Roberts	9c2d806556	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.	2013-11-02 12:53:31 -04:00
Jasper St. Pierre	13a7c8da85	display: Move the pointer event handling code to work in terms of Clutter events There is now a meta_display_handle_event alongside the meta_display_handle_xevent function which handles events in terms of Clutter events instead of X events. A Clutter event filter is registered so that all Clutter events will pass through this function. The pointer event handling code from the X event version has been moved into this new function and has been modified to use the details from the Clutter event instead of the X event. This is a step towards moving all of the event handling code over to use Clutter events. Based-heavily-on-a-patch-by: Neil Roberts <neil@linux.intel.com>	2013-11-02 12:53:30 -04:00
Jasper St. Pierre	d69d566087	display: Split out other event handling as well This vastly simplifies the code in event_callback and allows us to potentially take more of this logic and punt it to Wayland-specific backends.	2013-11-02 12:35:59 -04:00
Jasper St. Pierre	b722274886	display: Split out input event handling This helps with git's diff code by moving all the giant indentation changes, letting us know what's going on better when we move to Clutter for event handling.	2013-11-02 12:35:59 -04:00
Jasper St. Pierre	164cdabb21	display: Rename filter_out_event to bypass_gtk This clarifies the intent of the variable and makes it match bypass_compositor	2013-11-02 12:35:59 -04:00
Jasper St. Pierre	0b025f0e9c	display: Move barrier event processing to barrier.c This puts all the code that's easily ported to Clutter events in one giant switch statement, as Clutter doesn't translate barrier events.	2013-11-02 12:35:58 -04:00
Jasper St. Pierre	87354bdac6	display: Add a quick out path to handle_xevent This makes the code flow more like the scheme we usually use, and allows us to flatten out the method somewhat.	2013-11-02 12:35:58 -04:00
Neil Roberts	02e163882a	display: Rename meta_display_handle_event to meta_display_handle_xevent The plan is to make a new version of meta_display_handle_event that will accept Clutter events instead of X events and then gradually move over the events to the new function and finally remove the X version.	2013-11-02 12:35:58 -04:00
Giovanni Campagna	9db02a7379	wayland: sync the keymap from X to wayland When X clients change the keyboard map, the also update a property on the root window. We can notice that and rebuild our data structures with the new values, as well as inform the wayland clients. This is a terrible hack, and it's not how we want to implement things in 3.12, but it's enough to have the same keyboard layout in the shell, in X clients and in wayland clients in 3.10, until we decide on the fate of the keyboard g-s-d plugin. https://bugzilla.gnome.org/show_bug.cgi?id=707446	2013-11-02 12:35:58 -04:00
