This is necessary for gnome-shell to know whether it should try to
replace the org.gnome.Shell DBus name.
Note: We can't just #include <meta/util.h> because it #defines '_'
at least which obviously conflicts with core gettext. We should
un-export util.h or fix it.

As the position of attached modal dialogs is determined entirely
by the position of the parent window, the dialog may end up
partially off-screen (especially if the dialog is wider than the
parent). In this case, diverge from the calculated position and
try to fit the dialog on-screen.

This is useful for DnD to another monitor in gnome-shell.
In addition to a normal move it corrects the saved rect for
maximized and fullscreened windows.
https://bugzilla.gnome.org/show_bug.cgi?id=645032
Currently attached modal dialogs are not resizable, but we don't
communicate this to GTK+, so the dialog may end up with resize
grips anyway. As a fix, allow resizing, but account for the dialog
being centered to its parent.

Getting the contents of a depth-1 pixmap through cairo gives us
an alpha pixmap. We need to convert to a monochrome pixmap
as is expected by the ICCCM definition of WM_HINTS.
https://bugzilla.gnome.org/show_bug.cgi?id=641975
apply_mask made some wrong assumptions that became untrue
after rendering_cleanup landed, such as the number of channels
in the pixmap, causing corruption.
https://bugzilla.gnome.org/show_bug.cgi?id=641975
Currently, attached modal dialog can be grabbed (either by the
title bar, or using Alt+Button1), though they won't move when
dragged. To address this, grab the parent in that case, which
allows to move both the parent and the attached dialog.

Commit 96c43866 changed the tiling behavior to prefer edge tiling
over maximization in corner cases (well, quite literally). As a
side effect, it only allows untiling of edge-tiled windows by
dragging the window towards the correct edge.
This patch restores the old behavior for untiling, while keeping
the new behavior for untiled windows.
https://bugzilla.gnome.org/show_bug.cgi?id=645455
For tiling, we check whether the pointer is near the edges of
the monitor where the pointer is located, so checking that the
pointer is within the bounds of the monitor is unnecessary and
confusing.
Mark that the the third argument to meta_rectangle_union and
meta_rectangle_intersect is an (out) argument that should be created
by the language binding.
https://bugzilla.gnome.org/show_bug.cgi?id=645247
If dragging the title bar to the edge of the screen to side-tile,
it's easy to end up above the workarea and end up maximized instead.
Make the entire side of the screen act as edge-tiling.

In a performance or regression testing environment, we may want to
only manage windows from a particular test program, and ignore all
other windows. The MUTTER_WM_CLASS_FILTER environment variable is a
list of WM_CLASS values that should be managed; other windows will
be unmapped and ignored.
https://bugzilla.gnome.org/show_bug.cgi?id=644252
gtk3 no longer has the --screen command-line argument, which mutter
was passing to zenity. Use --display (with an explicitly-specified
screen number) instead.

This made sense back in the day of stateless window managers,
but gnome-shell isn't. gnome-session will handle gnome-shell
crashing, since it's a required component.
https://bugzilla.gnome.org/show_bug.cgi?id=644529
This adds a preference that when enabled makes all windows not on
the primary monitor be visible on all workspaces (i.e. not part of the
workspace switching handling).
https://bugzilla.gnome.org/show_bug.cgi?id=609258
Sometimes on_all_workspaces is requested by the client/user, and sometimes
its calculated implicitly due to internal state. We split this up so that
we know when the user has explicitly asked for sticky window, when e.g.
setting wmspec properties or storing session info.
on_all_workspaces means this window is visible on all workspaces.
on_all_workspaces_requested, means the user explicitly made the window
sticky somehow (via imported session, _NET_WM_STATE from another wm,
toggled in the window menu, etc). It always implies on_all_workspaces is
TRUE.
Right now the only time we set on_all_workspaces is for override-redirect
windows, but later we can add a "windows on non-primary monitor are not
part of the workspace switching" feature.
https://bugzilla.gnome.org/show_bug.cgi?id=609258
Until the actor is destroyed, we need to have access to the
MetaWindow to access some fields used for painting. Keep a strong
reference to the window rather than just hoping the window will
not be freed.

We don't actually use the full xrandr to get the primary monitor, we
just rely on the xrandr xinerama compat code to return the primary
monitor first. This lets us avoid adding unnecessary xrandr code and
avoids issues with _NET_WM_FULLSCREEN_MONITORS monitor indexes being
defined wrt xinerama monitor index order.
https://bugzilla.gnome.org/show_bug.cgi?id=609258
The latter move method will place the window by the origin of the
enclosing window decoration/frame, while the former will place by the
origin of the inner window, itself.
(Also moved meta_window_showing_on_its_workspace comment into
gtk-doc)
https://bugzilla.gnome.org/show_bug.cgi?id=642355
When reload_net_wm_state() is called at startup to read the initial
value of _NET_WM_STATE, it was calling recalc_window_type(), but not
recalc_features(), which meant that, eg, meta->skip_taskbar would
never get initialized from meta->wm_state_skip_taskbar, which meant
that next time mutter went to update the window's _NET_WM_STATE, it
would overwrite the app-specified initial values. Fix that.
(In metacity, this bug is masked by the fact that recalc_features()
gets called when reading the intial value of WM_NORMAL_HINTS, which
comes after _NET_WM_STATE in metacity's prop_hooks_table. In mutter,
the table got reordered at some point, exposing the bug.)
https://bugzilla.gnome.org/show_bug.cgi?id=624360
If mutter is going to be a "real" library, then it should install its
includes so that users can do
#include <meta/display.h>
rather than
#include <display.h>
So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.
There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,
but that wasn't really working anyway. So move all non-installed
headers back into core/ or ui/.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
Move all of the mutter code into a new libmutter-wm.so, split its
main() method into meta_get_option_context(), meta_init() and
meta_run(), add methods for using in-process plugins, and add
libmutter-wm.pc pointing to the new library.
The mutter binary is now just a tiny program that links against
libmutter-wm. The --version and --mutter-plugins options are handled
at the mutter level, not in libmutter-wm, and a few strange unused
command-line options (--no-force-fullscreen and --no-tab-popup) have
been removed.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
meta_restart() was broken, in that it restarted mutter with what was
left of argv after GOption and Clutter had possibly modified it.
Rather than try to fix this, just remove it.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
Revert the early_initialize changes (which get in the way in the
"libmutter-wm" paradigm), remove the GConf key for setting plugins,
and remove plugin "params", which weren't being used. Also remove all
the logic for unloading and reloading plugins, since the list never
changes after startup now.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
This changes the introspection configure flag from
--with/--without-introspection to --enable/--disable-introspection,
and changes it so that trying to enable introspection when g-i is not
installed results in an error, rather than being silently ignored.
https://bugzilla.gnome.org/show_bug.cgi?id=643959
It looks amazingly lame if we simply call exit() during logout. While
it's true that for applications that use XSMP, gnome-session will
close them before us, that doesn't do anything for non-XSMP apps,
which we really hope is the common case.
Instead, we just go away when the X server does.
https://bugzilla.gnome.org/show_bug.cgi?id=643437
For GNOME Shell, we need to grab our DBus names *before* we talk XSMP.
gnome-session takes our XSMP connection as "I'm ready", and starts
running all the other random crud that people dropped in as autostart
files. But for example, we need to have claimed
org.freedesktop.Notifications before a lot of said crud starts.
This requires a plugin API version bump.
Misc: Move handling of --version way earlier in main() where
it should be; no point having it wedged after plugin handling.
If we handle a key event then passing it to GTK+ as well can only
cause confusion. Normally GTK+ would do nothing with a key event for
some window it doesn't know about, but plugins might be doing more
things with the GTK+ event queue.
https://bugzilla.gnome.org/show_bug.cgi?id=642426
If a plugin was explicitly specified, falling back to the default
silently is bad; a manager component like gnome-session can
do a better job of handling this scenario.
An example we've hit in gnome-shell is where SpiderMonkey changes
without gjs being rebuilt, and loading the plugin fails due to
unresolved symbols.
But there are obviously others, like the file being missing or
corrupt.
https://bugzilla.gnome.org/show_bug.cgi?id=641384
Similar to the recently added 'size-changed' signal, we may want to do
something in response to a window being repositioned without waiting for
notify::allocation. (Especially since what we can do in notify::allocation
is severely limited by Clutter forbidding queueing an allocation at that
point.)
https://bugzilla.gnome.org/show_bug.cgi?id=641310
If we are previewing hidden windows, we might be previewing them in a context
like a thumbnail view of a workspace where we care about positioning. So, instead
of waiting until the window is first actually shown to place it, if
live_hidden_previews is set, place the window window when we first compute its
visibility, even if we don't end up showing it.
https://bugzilla.gnome.org/show_bug.cgi?id=641309
A plugin that does workspace management on its on may want to set the
workspace layout without having to deal with putting a property
on the root window to be read back and parsed.
Add meta_screen_override_window_layout() that allows the same types
of layouts as _NET_DESKTOP_LAYOUT but without setting a property.
https://bugzilla.gnome.org/show_bug.cgi?id=640552
A logic bug was resulting in the bottom hidden window (hidden means means
minimized or on a different workspace) continually being stacked above
the other hidden windows.
https://bugzilla.gnome.org/show_bug.cgi?id=640679
When we delete a workspace before the active workspace, we need
to upate the _NET_CURRENT_DESKTOP since the active workspace index
changes. To do this workspace.c:set_active_space_hint() is moved
to screen.c:meta_screen_set_active_workspace_hint() so that it
can be shared.
