ClutterActors for hidden windows (such windows on different than active
workspaces and windows that are minimized) are available, and reflect the
actual state of the window. This is intended for use in task-switchers etc.
This feature is disabled by default (due to increased demand on resources),
and can be enabled through the metacity/general/live_hidden_windows gconf key.
A trivial sample window switcher is included in the scratch plugin (activated
by clicking on the slide out panel).
terse variable names, simplify the plugin interface or consider tweaks
for maintainability.
* Renames plg -> plugin
* Renames mgr ->plugin_mgr (since in a combined window and composite
manager I think "mgr" will end up being ambiguous in places)
* Renames PluginWorkspaceRectangle -> MetaRectangle (We are no longer
concerned about mbwm2 portability)
* Renames a few one letter variable names e.g. a -> window, r ->rect
* Renames some vars to indicate what they represent not their data type,
e.g. group1, group2 ->workspace0, workspace1
* Renames the variable mcw -> mc_window to make it more immediately
obvious what it represents.
* Removes the verbose META_COMPOSITOR_CLUTTER_PLUGIN_SWITCH_WORKSPACE macro,
and just uses metacity_plugin instead.
* Instead of hanging data of the plugins global descriptor, we just use a
standalone static global variable.
* Make do_init a function pointer inside the plugin descriptors instead of
special casing it and using another g_module_symbol call. This also removes
the need for the META_COMPOSITOR_CLUTTER_PLUGIN_INIT_FUNC macro.
* A bunch of anal 80char fixes
* Removes the screen_width,height variables from the plugin descriptor struct
and add a plugin API instead.
The actor's private data created by the compositor is allocated
using g_new(), but since we are allocating a lot of small structures
all the time it's better to use the slice allocator instead.
Also, use a GQuark instead of using a string, so that the quark
lookup is done only once and the rest of the time is just an
integer comparison.
