There's no relation between a window being hidden from overview/taskbars
and a window not being closable - currently we effectively disable the
fallback quit action for any application with open transients, which
simply doesn't make sense.
Instead, only exclude windows for which the close action has been
explicitly disabled.

Using a single resource file for all JS sources saves a couple of
build system instructions, but has some serious downsides:
- bundling the entire shell code with the tools blows
up their size unnecessarily
- the tools are rebuilt unnecessarily for any shell
code change
Autotools was painful enough to let this slip, but with meson we
don't have any excuses - using the actual dependencies speeds up
the build a tiny bit and reduces the tools' sizes from over 2M
to about 50k.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/192
Simply reusing the same dependencies as gnome-shell itself not only
means that we link tons of stuff unnecessarily, but also that we
have to do the whole mutter rpath dance for nothing. Just use the
dependencies those executables actually need for a nice cleanup.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/192
We need this in the main gnome-shell executable in order to locate
the private Shell and St typelibs, but those aren't useful or even
usable in the extension-prefs/portal helper tools.

GSettings now recognizes per-desktop overrides that can be used
to change schemas' default values for a particular desktop. This
is not entirely unlike our existing custom override mechanism in
mutter, except that it is not limited to keys in org.gnome.mutter,
and it doesn't require a separate schema - the latter means that
we (and gnome-teak-tool) no longer have to figure out the correct
schema for the current login session and just use the original one.

Add a debug command (to be executed manually via Alt+F2) to check
that all of gnome-shell's file descriptors have the CLOEXEC flag set.
This is important so that internal file descriptors do not get passed
to apps when they are launched.
It prints a warning message for every fd that does not have the flag set.
fdwalk() is used from the standard library if available (it is not
available in glibc), otherwise we use the same implementation as glib
has internally.
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/132
When the amount of free memory on the system is somewhat low, gnome-shell
will sometimes fail to launch apps, reporting the error:
fork(): Cannot allocate memory
fork() is failing here because while cloning the process virtual address
space, Linux worries that the thread being forked may end up COWing the
entire address space of the parent process (gnome-shell, which is
memory-hungry), and there is not enough free memory to permit that to
happen. This check is somewhat irrelevant because we are only forking
to immediately exec(), which will discard the whole virtual address
space anyway.
This issue can be avoided by using a new optimized gspawn codepath in
the latest glib development version, which uses posix_spawn() internally.
For the optimized codepath to be used, we must not pass a child_setup
function, so the the file descriptor management is reimplemented here
using new glib API to pass fds to the child process. The old API will
continue to be used on older glib versions.
We must also change the spawn flags for this code path to be hit.
I checked that gnome-shell's open file descriptors are all CLOEXEC
so using G_SPAWN_LEAVE_DESCRIPTORS_OPEN should be safe.
This will result in more resilient app launching when memory is low,
since the optimized spawn path avoids cloning the virtual address
space of the parent process (gnome-shell) and avoids the irrelevant
memory overcommit check.

While can_open_new_window() uses some elaborate heuristics to predict
whether an application can open multiple windows, open_new_window()
will always simply relaunch the application. This is often the best
we can do, but when an application provides a "new-window" action in
its .desktop file or on the bus, it is much more likely to work as
expected than blindly activating the app and hoping for a particular
behavior.

Graphical applications like GIMP or GIMP allow picking colors from
any location on-screen. In order to keep supporting this feature
on wayland and in sandboxed apps, we will expose an appropriate
method in the Screenshot interface, so first add a corresponding
method to ShellScreenshot.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/286
A custom callback type is more convenient, but only as long as no
other callback type is required. We are about to add functionality
that does not return the filename to a screenshot saved on disk, so
prepare for that by moving to GIO's generic async callback pattern.

So that we can be started by systemd --user, instead of gnome-session.
There are three units:
- gnome-shell.service: Start gnome-shell itself.
- gnome-shell-x11.target, gnome-shell-wayland.target: Sync points for
units that need to care if x11 or wayland is in use.
gnome-settings-daemon will use these, for example.

All adjustment setter functions take good care of avoiding emission of
notify:: when it's not needed. The set_property() implementation already
calls into the setter functions, so mark the properties as EXPLICITY_NOTIFY
in order to optimize notify:: emission away through g_object_set (rather
common from JS code).
The actor allocation doesn't change per-se, but apply_transform()
will practically transform it. In order to have the paint volume
update accordingly, queue a relayout.
The default get_paint_volume() implementation will do the union
of children, and the child ClutterText paint volume may expand
beyond StEntry size when text overflows.
We actually want all content to be clipped to the StEntry, so
implement get_paint_volume() and tell it so.
And constrain it in StScrollView instead (instead of falling back to an
infinite paint volume, as the actor as paint/pick impls, but no
corresponding get_paint_volume one).
Fixes artifacts with the AppView (and possibly other places) when paint
volumes are aggressively cached.
Remove any usage of MetaScreen, as it has been removed from libmutter
in the API version 3. The corresponding functionality has been moved
into three different places: MetaDisplay, MetaX11Display (for X11
specific functionality) and MetaWorkspaceManager.

The default keyed_surface is meant to handle CoglTextures thus we can't
add cairo surfaces to it, as the DestroyNotify function won't handle them.
Then the quicker way is to just add another Hash table for handling
such types of textures, with proper destroy function.
This might cause a crash when cleaning up the cache as the hash table has
cogl_object_unref as DestroyNotify function but that assumes that
the passed object is a valid CoglObject.
Fixes: #210
The instance is owned by the actor (being its child), and thus when the
disposal happens for the parent the text is disposed too, thus it's just
safer to nullify its reference so that we won't try to access to invalid
objects later, and this might be the case since the JS objects could be kept
around until they aren't finalized.

The gnome-shell-calendar-server calls to refresh queries even when it
has no time range set, which results in:
a) waste of resources (for example after login),
b) many runtime warnings in the journalctl log, related to
incorrect time range being used.

While it is theoretically fine to run --perf=hwtest without passing --hwtest,
the test will hang in this case because it fails to start gedit. Always append
Gedit to the default value for --extra-filter when running the "hwtest" test
to make it work fine without --hwtest.
Call _st_set_text_from_style() when updating the entry's style, so
that CSS style properties such as text-decoration or letter-spacing
are applied over the internal ClutterText instance.
If an actor is pending a relayout when get_allocation_box() is called,
the method forces an allocation update. In case of StWidget, this might
then result in a style update and a consecutive invalidation of the
shadow spec.
A helper method that invalidates one of its parameters as a side effect
(and by extension its return value as well) is most unexpected, so cur-
rently _st_create_shadow_pipeline_from_actor() poses an easy trap to
callers to run into.
Remove that trap by calling get_size()/get_position() instead, which
don't have the unintended side effect - it is still a good idea to fix
callers who were running into this to not waste resources on creating
shadows that are invalidated before the next paint, but throwing un-
defined behavior at them is harsh ...

The imagedir and userdatadir variables are not fetched from
constants/environment but created with g_strdup*/g_build*. Acknowledge that
and also free the strings in finalize.
Whenever a new cursor image is loaded also save it's hot x/y
coordinates. The drawing code already respects these values, however
they were never set. This change will place the cursor image at the
correct location as seen on screen. shell-screenshot.c served as

The st_button_release() call wouldn't happen because StButton does not
set priv->button_mask on touch events. And if we make it called, we can't
try to unset the device grab at the end of the function, as device/sequence
are unset earlier on.
After we receive one of the tracked signals, in case we get stuck inside
the gjs_dumpstack () call, we use an alarm to raise the previously emitted
signal, however without using SA_NODEFER, the raise inside the alarm handler
will be ignored.
To avoid to handle new signals caused by the handler calls, once we get the
first signal, we just ignore them all as they could only lead to dirty traces.
Also, cleaning up a bit the code, and disabling the shell log handler
in dump_gjs_stack_alarm_sigaction since this might lead to a new
gjs_dumpstack () request.
https://bugzilla.gnome.org/show_bug.cgi?id=789237
In order to debug issues triggered by JS code we might need to
see the stack of it, this is not normally visible in static stack traces,
thus we need to call gjs_dumpstack () before dying the process.
Intercepting signals SIGABRT, SIGTRAP (needed for catching fatal glib
errors) SIGFPE and SIGIOT by default, while introducing a new
'backtrace-segfaults' flag for the SHELL_DEBUG environment variable to
do the same on SIGSEGV and SIGBUS (this is a precaution to avoid that we
corrupt the stack for automatic errors trackers).
In any case after dumping the stack we raise the signal again, in order
to make the system aware of it.

Similar to what it's done in _shell_app_add_window(), rely on calling
shell_app_sync_running_state() when removing windows too, to avoid
transitioning to STOPPED while it's still in the STARTING state.
This makes the logic compliant with the startup notification spec and
prevents stopping an application too early if it has a splash screen
that has been closed before the application's main window is shown.

Meson now warns when specifying the rpath in linker flags instead

When creating a shadow for a ClutterTexture, we currently use the
underlying CoglTexture directly instead of rendering the actor to
an offscreen buffer. This assumes that the CoglTexture is directly
suitable as shadow source, which isn't necessarily the case - it
may have a very different size than what is shown and scaled up or
down by the hardware. In that case we end up with a scaled shadow
texture as well, which messes up the desired blur effect - the
result will be too light when scaling up, or too sharp when scaling
down. To fix this, only take the shortcut when a ClutterTexture's
underlying texture has the correct size and fall back to offscreen
rendering otherwise.

If a tray icon gets a mapped and unmapped and the mapped again
in quick succession, we can end up with multiple handlers
listening for window creation events.
This commit tries to guard against that by only listening for
window-created events when we don't know the actor associated
with the icon.

Unlike pango_font_description_from_string(),
pango_font_description_set_family() requires a already properly
formatted font family string. The proper format is a comma seperated
list of font families, but we generated a "comma space" separated list.
Passing a incorrectly formatted font family string to pango seems to
cause wierd issues, where the wrong font is sometimes selected.
For example, this fixes a font selection issue on zh_TW.UTF-8 locale for
chinese characters, where previously the "Droid Sans" font was selected
instead of "Source Han Sans TW" even though fontconfig had placed
"Source Han Sans TW" before "Droid Sans".

The theme widget passed to shell_tray_manager_manager_screen() is simply
a means to receive style information. There is nothing which ties the two
object's life cycles together, so it is entirely possible for the tray to
be finalized with the widget still around - we shouldn't try to update the
stale object on widget style changes, so make sure we properly disconnect
the signal handler.

Compiling the generated source for each consumer of the dependency
means we end up trying to register the enum types multiple times,
resulting in a fatal failure on startup. Luckily code outside libst
itself only depends on the header, which doesn't cause those issues.
st_built_sources contains the source and header generated by mkenums,
not any other generated sources. Clarify that in the name, as we are
about to use source and header separately.
We cannot rely on any build order, except the one we specify ourselves.
St depends on various generated files; other targets depend on those
files existing, so they can be included. There is no direct relationship
between targets and files, unless we declare a dependency, using the
Meson declare_dependency() constructor — which allows us to replace the
various `link_with` directives with the more appropriate `dependencies`
one, and also allows us to specify sources that must exist by the time
we build those targets.
In parallel builds we may end up with st-enum-types.c being built inside
separate targets outside of src/st which may not have the ST_COMPILATION
pre-processor symbol defined. For this reason, we need to define it
ourselves in the source file, before including other headers, to avoid
the single-include guard.
This is not strictly necessary when linking the shell with DT_RPATH as
the runtime paths will be extracted from the introspected libraries and
used from gobject introspection to find them when loading them based on
the typelib files, but when linking with DT_RUNPATH, as it's the case
for some linkers (e.g. ld.gold, or ld.bfd in some distros like Debian).
By explicitly prepending this directory as a library path for GIR, we're
making sure that the wrapped shared objects installed in Mutter's and
GNOME Shell's private directories can be found in all cases.

Otherwise UTC is used which results in a different interpretation of

This is the same as the previous commit, but for StEntry.
We don't have any need to explicitly destroy this actor in our dispose
implementation, and doing so breaks the assumption that we can access
the clutter_text from within destroy.

There's no need to explicitly destroy the ClutterText actor inside the
label; doing so is actually harmful, as it will break the normal
reference cycle between container and children.
As StLabel doesn't hold any extra reference to the ClutterText actor and
just uses clutter_actor_add_actor() to add it to itself, let the normal
container dispose cycle run to dispose of the reference.

The static library was split out to avoid duplicate compilation
