find_focusable_ancestor() may pick an ancestor window which is not
mapped or hidden, and setting focus on that window will fail.
Be a tad more selective when looking for a focusable ancestor, to reduce
the chance of meta_window_focus() not focusing the happy chosen one.
Part-of: <https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1643>
The function focus_default_window() optionally takes a MetaWindow
argument denoting a window that should not be focused.
That function calls focus_ancestor_or_top_window() which in turn
calls meta_window_focus() to pass focus to another window.
However meta_window_focus() gives no guarantee that the given window
will end up being the one focused, and can fail in various and creative
ways.
If that fails, we could possibly end up with the focus window being the
one to avoid, while the caller assumes focus was changed, going as far
as asserting that fact like meta_window_unmanage() does.
As a result, mutter may abort simply because meta_window_focus() failed
to set focus on the expected window.
To avoid that issue, check that the focus did not end up on the window
that we explicitly did not want, and if that's the case, simply fallback
to the default focus window.

There are a couple of places in gnome-shell where we aren't interested
in which workspace is active, but whether a given workspace is active.
Of course it's easy to use the former to determine the latter, but we
can offer a convenience property on the workspace itself almost for
free, so let's do that.

This is so that cogl-trace.h can start using things from cogl-macros.h,
and so that it doesn't leak cogl-config.h into the world, while exposing
it to e.g. gnome-shell so that it can make use of it as well. There is
no practical reason why we shouldn't just include cogl-trace.h via
cogl.h as we do with everything else.

When destroying a window that has a parent, we initially try to focus one of
its ancestors. However if no ancestor can be focused, then we should instead
focus the default focus window instead of trying to request focus for a window
that can't get focus anyways.
Fixes https://gitlab.gnome.org/GNOME/mutter/issues/308
In all places (including src/wayland) we tap into meta_x11_display* focus
API, which then calls meta_display* API. This relation is backwards, so
rework input focus management so it's the other way around.
We now have high-level meta_display_(un)set_input_focus functions, which
perform the backend-independent maintenance, and calls into the X11
functions where relevant. These functions are what callers should use.

GList's used in legacy code were free'd using a g_slist_foreach + g_slist_free,
while we can just use g_slist_free_full as per GLib 2.28.
So replace code where we were using this legacy codepath.

meta_workspace_activate_with_focus is supposed to focus the passed window after
switching the workspace.
However if the passed workspace is already the active one, we just return
without activating the window.
So fix this calling meta_window_activate on the foucs_this window if that is
valid.

The order and way include macros were structured was chaotic, with no
real common thread between files. Try to tidy up the mess with some
common scheme, to make things look less messy.
- Stop using CurrentTime, introduce META_CURRENT_TIME
- Use g_get_monotonic_time () instead of relying on an
X server running and making roundtrip to it
https://bugzilla.gnome.org/show_bug.cgi?id=759538
This moves following objects from MetaScreen to MetaDisplay
- workareas_later and in_fullscreen_later signals and functions
- startup_sequences signals and functions
- tile_preview functions

Split X11 specific parts into MetaX11Display. This also required
changing MetaScreen to stop listening to any signals by itself, but
instead relying on MetaDisplay forwarding them. This was to ensure the
ordering. MetaDisplay listens to both the internal and external
monitors-changed signal so that it can pass the external one via the
redundant MetaDisplay(prev MetaScreen)::monitors-changed.

Don't store logical monitor specific state in an array where the index
from the monitor manager is used as index locally. Instead just use
table associating a logical monitor with a monitor specific state
holder, and store the state in there. This way we don't have the
workspace implementation relying on implementation details of other
units.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Instead of storing the logical monitors in an array and having users
either look up them in the array given an index or iterate using
indices, put it in a GList, and use GList iterators when iterating and
alternative API where array indices were previously used.
This allows for more liberty regarding the type of the logical monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Move the last piece of monitor grid getter API to the monitor manager
away from MetaScreen. The public facing API are still there, but are
thin wrappers around the MetaMonitorManager API.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
Turning a rectangle into a logical monitor also has nothing to do with
the screen (MetaScreen) so move it to MetaMonitorManager which has that
information.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
To complement the current API which takes an index referencing a
logical monitor in the logical monitor array, add API that takes a
direct reference to the logical monitor itself. The intention is to
replace the usage of the index based API with one that doesn't rely on
internal implementation details.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
It was just pointer to the actual list; having to synchronize a list of
logical monitors with the actual monitors managed by the backend is
unnecessary.
https://bugzilla.gnome.org/show_bug.cgi?id=777732
In preparation for further refactorizations, rename the MetaMonitorInfo
struct to MetaLogicalMonitor. Eventually, part of MetaLogicalMonitor
will be split into a MetaMonitor type.

The constructor would collect windows that are sticky before initializing its state
which would lead to a crash in the case of windows with struts which trigger a work
area recalculation where mutter would assume, due to uninitialized state, that an
existing work area has to be freed.
https://bugzilla.gnome.org/show_bug.cgi?id=738384
Windows are relocated before their workspace is removed, however this
is only necessary for windows that are *only* on that workspace; for
windows on all workspaces, that step is annoying as it will unset the
sticky state requested by the user.
https://bugzilla.gnome.org/show_bug.cgi?id=737625
The workspace MRU lists are updated when windows are managed/unmanaged
or change workspaces. However those updates obviously only apply to
existing workspaces - new workspaces will always start out with an empty
MRU list, despite sticky windows already being "on" that workspace.
As we now assert that the list contains all windows located on the
workspace, we need to initialize it correctly to avoid a crash.
https://bugzilla.gnome.org/show_bug.cgi?id=737581
O-R windows appear in workspace->windows, which aren't relocatable,
so we can't simply check if the workspace is empty after relocating
all normal windows, since those windows remain.
Make sure that the only windows we have are those that are
on_all_workspaces.
The existing workspace management code is quite hairy, with plenty of
logic inline in all of window.c, workspace.c, and screen.c, making it
hard to understand or make changes to, since you might forget to change
several of the other places the code was around.
Rewrite the internal workspace management logic so that it's
centralized and all in window.c. Document the invariants we need to
maintain, and ensure that these invariants are properly kept, with
asserts in various places.
Extensive testing on gnome-shell did not bring up any issues, and this
is a considerable cleanup.
This will be used to replace some of the hooks that are used to call
into window.c, so that the workspace index property is properly kept up
to date.
We can't name the property "index" since it causes conflicts with the
meta_workspace_index method. This should really be called
meta_workspace_get_index, but oh well.
