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.

compositor.c: Move MutterWindow code to mutter-window.c;
rename map_win() to mutter_window_map(), etc.
mutter-window-private.h: New private header file for
MutterWindow functions used internally to the compositor.
compositor-mutter.h: Move MutterWindow declarations to
mutter-window.h; move a couple of private functions to
compositor-private.h
compositor-private.h: Move MetaCompScreen declaration to here:
Conceptually it's private to compositor.c, but MutterWindow
manipulates some of the lists directly for now.
mutter-plugin.c compositor.c: Don't call mutter_window_effect_completed()
for MUTTER_PLUGIN_SWITCH_WORKSPACE, but use a new
mutter_switch_workspace_completed(), since the window is
just used to identify a screen.

Separate code related to creating the gaussian-blurred shadow texture
into a separate file.
Move the definition of MetaCompositor into a compositor-private.h
so that the shadow code can cache the source in the compositor
structure.

Remove a number of functions that were either entirely unimplemented
or had empty implementations for the Clutter-compositor.
meta_compositor_begin_move()
meta_compositor_update_move()
meta_compositor_end_move()
meta_compositor_set_active_window()
meta_compositor_free_window()

Now that we only have one compositor, there's no reason to access the
compositor functions through a vtable. Remove the MetaCompositor virtualization
and make the clutter code implement the meta_compositor_* functions
directly.
Move the checks for the compositor being NULL from the vtable wrappers
to the calling code (most of them were already there, so just a few
needed to be added)
Note: the compositor is actually hard-coded on at the moment and the plan
is to remove the non-composited code entirely, so the checks are
added only to keep things neat: they have no practical effect.

Mutter is a Clutter-based compositing manager. So, remove the code for
the XRender-based compositor, and make it mandatory to have XComposite,
XRender and Clutter.
Run-time support for non-composited operation is left for now.
* src/compositor/mutter/: Move files from this subdirectory into
the main compositor/ directory.
* compositor/compositor-xrender.ccompositor/compositor-xrender.h:
Remove
* include/compositor-clutter.h: Remove this stray file, it had been
replaced with compositor-mutter.h some time back.

Since the stack passed to the compositor now accurately reflects
the X stacking order, we need to treat hidden windows (which are
at the bottom of the X stacking order) specially - when the
compositor stacking order is synced, try to keep animating hidden
actors in their old positions in the stack.

This reverts commit 16d49695ad.
If we want an actor to go away deterministically, we should call
clutter_actor_destroy(); using unparent instead a) may result
leaks through cyclic ref counts, and b) will delay the deallocation
of the window texture in a garbage collected environment until
the next garbage collection, causing much greater transient use
of memory.

info->pending_input_region needed to be destroyed in
mutter_set_stage_input_region() before it was set to something
else or before it was reset to be full screen (region == None).
Set the initial input area to an empty region by
setting info->pending_input_region to an empty region by default
and setting it to None or a new region if a new input region is
specified.
Remove show_overlay_window() function that was used to set an empty
input region on start-up, and uses a call to do_set_stage_input_region()
with info->pending_input_region as an argument instead.
Code:
All references in the code not related to themes, keybindings, or
GConf were changed from 'metacity' to 'mutter'. This includes, among other
things, strings, comments, the atoms used in the message protocol, and
the envvars used for debugging. The GConf schema file was reduced to
the 3 settings new to mutter.
The overall version was brought up to 2.27 to match current gnome.
Structure:
All files named '*metacity*' were renamed '*mutter*' with appropriate
changes in the automake system. Files removed are
doc/creating_themes, src/themes, doc/metacity-theme.dtd,
metacity.doap. These files will eventually end up in an external
gnome-wm-data module.
Installation location:
On the filesystem the mutter-plugindir was change from
$(libdir)/metacity/plugins/clutter to just $(libdir)/mutter/plugins.
The mutter-plugins.pc.in reflects these changes.
Note:
mutter.desktop.in and mutter-wm.desktop both continue to have
X-GNOME-WMSettingsModule=metacity set. This allows
gnome-control-center to continue using libmetacity.so for
configuration. This is fine since most the general keybindings and wm
settings are being read from /apps/metacity/* in gconf.
Change #define _XOPEN_SOURCE 500 to 600 in compositor-xrender.c to
avoid a bad interaction with -xc99 on Solaris.
Remove unneeded #define in compositor-mutter.c.

Cogl's default blend function has been switched to expect premultiplied

modulate alpha to match.

It doesn't make sense to allow the window texture to be sliced,
but not allow the mask texture to be sliced. So, we should either
set 'disable-slicing' for the texture actor or not pass NO_SLICING when
creating the mask texture.
While slicing currently results in only the first layer being shown,
disabling slicing entirely would break windows larger than the texture
size limit. It would be straightforward to support multitexturing of
sliced textures in Cogl when all the textures are identically sized
and sliced identically, if it became a priority.

- Use float instead of ClutterUnit
- clutter_actor_get_size/position() return floats (remove some
stray usage of these functions in the default plugin as well.)
- Adapt to cogl_texture_new_from_data() changes
- Use blend strings to set up multitexturing
- Remove CLUTTER_UNITS_TO_FLOAT() usage

If the input region has been shaped, then clutter needs to
receive EnterNotify/LeaveNotify events in order to properly
send enter and leave events to actors when the pointer crosses
the boundary of the stage.

If mutter_plugin_set_stage_input_region() and related methods are
called before the output window is available, save the set input
region and apply it to the output window later on.
compository-mutter.[ch]: Add mutter_set_stage_input_region() and
mutter_empty_stage_input_region(), move the input region handling
here and implement the delayed shape setting described
above.
mutter-plugin.c: Implement shape setting in terms of the new methods.

Using G_MODULE_BIND_LOCAL causes problems for introspecting plugins,
since introspected symbols need to be globally available. And in
any case, trying to use linker features to prevent symbol conflicts
doesn't usually work out very well, it's better to just namespace
properly.
http://bugzilla.gnome.org/show_bug.cgi?id=580033
Add separate mutter_plugin_manager_load() and
mutter_plugin_manager_initialize() calls so that we can just
load the plugins without start them. This is useful for introspecting
a gnome-shell plugin at build time.

To guard against CompositeNameWindowPixmap failing, just use an
error trap. Previous code used:
GrabServer/GetWindowAttributes/CompositeNameWindowPixmap/UngrabServer
To prevent BadMatch errors from !viewable, but didn't check the
return value of GetWindowAttributes and didn't check if an error
occured during the error trap. This way is more correct and more
efficient.

The overlay window was created before the plugins are loaded. Because the
composite extension immediately maps the window, we ended blanking the screen
while plugins, etc., were loading. This commit reorganizes the code so that
the overlay window is only created just before we are ready to show the
stage.
The significant impact of this change is that plugins cannot manipulate the
overlay window during their initial loading, i.e., they cannot call the
input-region API (the plugin should hook into the "show" signal if it needs
to do anything of this sort).
The commit also removes the XClearArea() call on the overlay window that
seems to have served no real purpose.
Once the window destruction is initiated, we can still manipulate our
MutterWindow with clutter API, but we can not longer use any X-based API,
or MetaWindow API to query it.
Add 'hide_after_effect' flag to MutterWindowPrivate, tracking
whether the window needs to be hidden after all outstanding effects
finish.
Set or clear the flag as appropriate in clutter_cmp_set_window_hidden.
In mutter_window_effect_completed, if hide_after_effect is TRUE
and no other effects are in progress, hide the window.
Requiring the compositor private object to be a GObject allows the
return value of meta_window_get_compositor_private() to be used
via gobject-introspection, since the type and memory management
can be determined.
This allows a reverse mapping from MetaWindow to MutterWindow.
- Change meta_window_get/set_compositor_private to use GObject
rather than void *
- Adapt code in compositor-mutter.c to match.
Now that Cogl has the material API we can use Cogl calls for
multi-texturing instead of directly calling GL.
The MutterShapedTexture actor keeps a handle to a material with the
right combine modes for combining the texture and the shape
mask. Before each paint it sets the layers of the material to be the
two textures.
A second material with different combine modes 1is also created if the
pixmap is 24 bit to implement the workaround from commit 72da8c57.
It seems that with the latest intel drivers when multi-texturing using an RGB
TFP texture, the texture is being setup internally as an RGBA texture, where
the alpha channel is mostly 0.0 so you only see a shimmer of the window. This
workaround forcibly defines the alpha channel as 1.0. Maybe there is some
clutter/cogl state that is interacting with this that is being overlooked,
but for now this seems to work. (Tested on i945 + DRI2)
The addition of method implementations in the base class in the
plugin-gobject branch broke the logic for checking to see
if a plugin didn't implement an effect. Requiring a mandatory
chain up to the base class is a fiddly anyways, so this patch
does the 'running' count computations in a different (and more
robust) way.
mutter-plugin.h mutter-plugin.c: Add _mutter_plugin_effect_started()
to increment the running count.
mutter-plugin-manager.c: Call _mutter_plugin_effect_started()
as necessary.
mutter-plugin.c: Remove the "real" methods that did nothing
but implement the runnning count.
plugins/default.c: Remove chain-ups.
Fix a problem where GTK+ was warning
'gdk_window_set_user_time called on non-toplevel' for every button
press and click on the mutter stage by excluding such events from
GTK+ processing.
Add a boolean return value to meta_compositor_process_event that
indicates whether the event has been handled and should be filtered
out of the event stream and for mutter, base that on the return
value of the plugin's xevent_filter vfunc.
Before we've retrieved a pixmap for a window, the shaped texture
has a 0x0 texture, which will cause mutter_shaped_texture_ensure_mask()
to crash. Just skip all of paint/pick in this case.
