a26ded47d9 Add a private gtk-mutter protocol
Add a new interface, gtk_shell, than can be used by gtk to
retrieve a surface extension called gtk_surface, which will be
used to communicate with mutter all the GTK extensions to EWMH

https://bugzilla.gnome.org/show_bug.cgi?id=707128

Add support for GTK application menus

To do so, we need to be able to set surface state before creating
the MetaWindow, so we introduce MetaWaylandSurfaceInitialState as
a staging area.
The gtk-shell-surface implementation would either write to the
initial state, or directly to the window.

At the same, implement set_title and set_class too, because it's
easy enough.

214f31257b Rework and consolidate monitor handling in MetaScreen
Consolidate all places that deal with output configuration in
MetaScreen, which gets it either from XRandR or from a dummy static configuration.
We still need to read the Xinerama config, even when running xwayland,
because we need the indices for _NET_WM_FULLSCREEN_MONITORS, but
now we do it only when needed.

40e820f551 Add support for stacking X and Wayland windows together
This breaks down the assumptions in stack-tracker.c and stack.c that
Mutter is only stacking X windows.

The stack tracker now tracks windows using a MetaStackWindow structure
which is a union with a type member so that X windows can be
distinguished from Wayland windows.

Some notable changes are:

Queued stack tracker operations that affect Wayland windows will not be
associated with an X serial number.

If an operation only affects a Wayland window and there are no queued
stack tracker operations ("unvalidated predictions") then the operation
is applied immediately since there is no server involved with changing
the stacking for Wayland windows.

The stack tracker can no longer respond to X events by turning them into
stack operations and discarding the predicted operations made prior to
that event because operations based on X events don't know anything
about the stacking of Wayland windows.

Instead of discarding old predictions the new approach is to trust the
predictions but whenever we receive an event from the server that
affects stacking we cross-reference with the predicted stack and check
for consistency. So e.g. if we have an event that says ADD window A then
we apply the predictions (up to the serial for that event) and verify
the predicted state includes a window A. Similarly if an event says
RAISE_ABOVE(B, C) we can apply the predictions (up to the serial for
that event) and verify that window B is above C.

If we ever receive spurious stacking events (with a serial older than we
would expect) or find an inconsistency (some things aren't possible to
predict from the compositor) then we hit a re-synchronization code-path
that will query the X server for the full stacking order and then use
that stack to walk through our combined stack and force the X windows to
match the just queried stack but avoiding disrupting the relative
stacking of Wayland windows. This will be relatively expensive but
shouldn't be hit for compositor initiated restacking operations where
our predictions should be accurate.

The code in core/stack.c that deals with synchronizing the window stack
with the X server had to be updated quite heavily. In general the patch
avoids changing the fundamental approach being used but most of the code
did need some amount of re-factoring to consider what re-stacking
operations actually involve X or not and when we need to restack X
windows we sometimes need to search for a suitable X sibling to restack
relative too since the closest siblings may be Wayland windows.

f9a11b3b18 wayland: Adds basic hybrid X + Wayland support
This adds support for running mutter as a hybrid X and Wayland
compositor. It runs a headless XWayland server for X applications
that presents wayland surfaces back to mutter which mutter can then
composite.

This aims to not break Mutter's existing support for the traditional X
compositing model which means a single build of Mutter can be
distributed supporting the traditional model and the new Wayland based
compositing model.

TODO: although building with --disable-wayland has at least been tested,
I still haven't actually verified that running as a traditional
compositor isn't broken currently.

Note: At this point no input is supported

531be6c413 Track the X Shape input region and use it for picking
We now track whether a window has an input shape specified via the X
Shape extension. Intersecting that with the bounding shape (as required
by the X Shape extension) we use the resulting rectangles to paint
window silhouettes when picking. As well as improving the correctness of
picking this should also be much more efficient because typically when
only picking solid rectangles then the need to actually render and issue
a read_pixels request can be optimized away and instead the picking is
done on the cpu.

7a4c808e43 display: clean up focus_window vs expected_focus_window
Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.

Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

97a4cc8c9b Make handling of windows that don't respond to _NET_WM_SYNC_REQUEST reliable
Previously, we were handling failure to respond to _NET_WM_SYNC_REQUEST
in the code path for throttling motion events. But this meant that
if a window didn't respond to _NET_WM_SYNC_REQUEST and there were no
motion events - for a keyboard resize, or after the end of the grab
operation - it would end up in a stuck state.

Use a separate per-window timeout to reliably catch the failure to respond
to _NET_WM_SYNC_REQUEST.

592374bc62 Fix freezing of windows with keyboard resizing
During resizing we froze window updates when configuring the
window, and unfroze the window updates when processing the
next resize. This wasn't absolutely reliable, because we might
not have a next resize. Instead tie window freezing more
directly to the current sync request value - a window is
frozen until it catches up with the last value we sent it
in _NET_WM_SYNC_REQUEST.

Testing with unresponsive clients showed that there was a bug
where window->disable_sync once set, would not actually disable
sync, but it *would* disable noticing that the client was
unresponsive for the next resize. Fix that by checking for
->disable_sync before sending _NET_WM_SYNC_REQUEST.

2cafb8be2d window: fix meta_window_is_remote across hostname changes
meta_window_is_remote compares a cached copy of the system hostname
with the hostname of the client window
(as presented by the WM_CLIENT_MACHINE property).

Of course, the system hostname can change at any time, so caching
it is wrong. Also, the WM_CLIENT_MACHINE property won't necessarily
change when the system hostname changes, so comparing it with the
new system hostname is wrong, too.

This commit makes the code call gethostname() at the time
WM_CLIENT_MACHINE is set, check whether it's remote then, and cache
that value, rather than comparing potentially out of sync hostnames
later.

5876f2e3e5 Fix corner cases where _NET_WM_FRAME_DRAWN might be missed
The WM spec requires _NET_WM_FRAME_DRAWN to *always* be sent when
there is an appropriate update to the sync counter value. We were
potentially missing _NET_WM_FRAME_DRAWN when an application did a

Refactor the code to always send _NET_WM_FRAME_DRAWN, even when
a window is frozen.

87fe9685b5 Distinguish "no delay" frames from spontaneous drawing
When a client is drawing as hard as possible (without sleeping
between frames) we need to draw as soon possible, since sleeping
will decrease the effective frame rate shown to the user, and
can also result in the system never kicking out of power-saving
mode because it doesn't look fully utilized.

Use the amount the client increments the counter value by when
ending the frame to distinguish these cases:

 - Increment by 1: a no-delay frame
 - Increment by more than 1: a non-urgent frame, handle normally

window are frozen until the counter is updated again to an even value.

7f8c59614e window: make determination of attached dialog windows more consistent
Different bits of code were using slightly different checks to test
whether a window was an attached dialog. Add a new
meta_window_is_attached_dialog(), and use that everywhere.

Also, freeze the is-attached status when the window is first shown,
rather than recomputing it each time the caller asks, since this could
cause problems if a window changes its type after it has already been
attached, etc. However, if an attached window's parent is destroyed,
or an attached window changes its transient-for, then fix things up by
destroying the old MetaWindow and creating a new one (causing
compositor unmap and map events to be fired off, allowing the display
of the window to be fixed up).

Remove some code in display.c that tried to fix existing windows if
the gconf setting changed, but which didn't actually do anything (at
least under gnome-shell). However, if 654643 was fixed then the new
behavior with this patch would be that changing the gconf setting
would affect new dialogs, but not existing ones.

9d62d13f88 Split out on_all_workspaces and on_all_workspaces_requested
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.

c84da3ce1b Move the installed includes to a subdir
If mutter is going to be a "real" library, then it should install its
includes so that users can do

    #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
