g_error() is the wrong thing to do when, for example, we can't find the
DRM device, since Mutter should just fail to start rather than reporting
a bug into automatic bug tracking systems. Rather than trying to decipher
which errors are "expected" and which not, just make all failure paths
in meta_launcher_new() return a GError out to the caller - which we make
exit(1).

The qxl kms driver has a bug where the cursor gets hidden
implicitly after a drmModeSetCrtc call.
This commit works around the bug by forcing a drmModeSetCursor2
call after the drmModeSetCrtc calls.
This is pretty hacky and won't ever go upstream.

The default theme started to use them in GTK+ commit 371f50, so
we need to update the style contexts to keep matching the style
of client-side decorations.

Ubuntu ships a patch in the X server that makes the group switch
keybindings only work on key release, i.e. the X server internal group
locking happens on key release which means that mutter gets the
XKB_KEY_ISO_Next_Group key press event, does its XLockGroup() call
with a new index and then, on key release, the X server moves the
index further again.
We can work around this without affecting our behavior in unpatched X
servers by doing a XLockGroup() every time we're notified of the
locked group changing if it doesn't match what we requested.

In a HiDPI environment, all gtk+ apps will report a 2 x 2 size
increment to avoid odd size. But that does not mean they are
resizing in cells like terminals, so they resize popup should
not be shown.
Ideally, we should ignore <= scale x scale increments, but in
practice scale is 1 or 2, and even in a lo-dpi setting a 2 x 2
increment makes little sense so let's keep the patch simple.

Right now we just check the pointer serial, so the popup will be
immediately dismissed if the client passes a serial corresponding to
another input device.
Abstract this a bit further and add a meta_wayland_seat_can_popup() call
that will check the serial all input devices. This makes it possible to
trigger menus through touch or keyboard devices.

We might get modes in XRROutputInfos that aren't in the
XRRScreenResources we get earlier. This always seems to be transient,
i.e. when it happens, the X server will usually send us a follow up
RRScreenChangeNotify where we then get a "stable" view of the world
again.
In any case, when these glitches happen, we end up with NULL pointers
in the MetaOutput->modes array which makes us crash later on. This
patch ensures that doesn't happen.

If we immediately dismiss the popup, we still need to set the
surface->xdg_popup pointer field in order for the destructor to
properly clean up the state. Not doing this may cause a crash if the
xdg_popup resource that was immediately dismissed is destoryed after
wl_surface during client destruction.

We have been ignoring those buttons since 3.16 after they had been
broken in the default theme for a couple of versions. As nobody
appears to miss them, it's time to remove them for good.
We use a single style context to draw titlebar buttons, updating
its state according to each button's prelight state as necessary.
This assumes that the original state is neither ACTIVE nor PRELIGHT,
which means we need to reset the state after drawing to avoid
propagating the state of the last-drawn button.
Displaying all Wayland windows with the XID of 0x0 makes it hard
to figure out what is going on ... use the recently-added
window->stamp to show Wayland windows as W1/W2/W3...
Some windows, like Chromium and Steam, are technically CSD in that they
don't want a system titlebar and draw their own, but we should still
provide them with a shadow.
Both Window and XSyncCounter are XIDs which on 64 bit X clients are 8
bytes wide. But the values on the wire are 32 bit so, for these types,
we always copy 4 bytes into results->prop. As such copying them out
with a cast such as *(Window *) means that we are actually reading 8
bytes which depending on whether the higher addressed 4 bytes are zero
means that sometimes this works while others it gives us a bogus
value.

We don't have any way of knowing what the intended size of a XWayland
cursor is supposed to be, so lets do what we do with regular XWayland
surfaces and don't scale them. The result is that cursor sprites of
HiDPI aware X11 clients will show correctly, but non-aware clients may
have tiny cursor sprites.

Each keyboard focus change ends up calling the MetaWaylandDataDevice
counterpart, we don't need though to notify the current selection
again. In order to fix this, keep track of the current client, and
only emit the relevant signals when the focus switches to another
client.
The situations where wl_data_device.selection were emitted during
focus changes between surfaces of the same client was inocuous most
of the times, although it's prone to inducing confusing behavior
on context menu clipboard actions, as the closing menu triggers a
focus change, which triggers a whole new wl_data_offer being created
and given on wl_data_device.selection, at a time where there's already
ongoing requests on the previous data offer.

If the transfer is cancelled, the X11SelectionData will be cleared from
the MetaSelectionBridge, although x11_data_write_cb() was invariably
expecting it to be non-NULL.
If the write was cancelled, all the actions done in x11_data_write_cb()
are moot, so just return early. If there's other errors happening
(eg. "connection closed" if the target client happens to crash), we
should still attempt at clearing the data anyway.

When committing a toplevel surface we might no longer have a MetaWindow
associated with it. The reason may vary but some are: a popup was
dismissed, the client attached and committed a NULL buffer to a
wl_surface with the wl_shell_surface role, the client committed a
buffer to a wl_surface which previously had an toplevel window role
which extension object was destroyed.

If the drag dest surface suddenly disappears, we may find ourselves
processing an XdndPosition message that was sent before the X11 drag
source had an opportunity to find out.
In that case mutter does know, so double check before processing the
messages.
We try to translate the atom with its corresponding mimetype both back
and forth, which actually breaks if the X11 client chose to announce the
mimetype atom. To do the translation properly, keep track on whether the
source announced the UTF8_STRING atom, and reply back with this only if
that happened.
If the wayland surface isn't available yet when we process the
WL_SURFACE_ID ClientMessage, we schedule a later function to try the
association again after we get a chance to process wayland requests.
This works fine except on cases where the MetaWindow already had a
previous surface attached (i.e. when the xwindow is reparented) since
we only break the existing association on the later function which
means that when processing the old surface's destruction we destroy
the MetaWindow and cancel the pending later function leaving us
without a MetaWindow and an invisible surface.
Fix this by detaching the old surface as soon as possible so that the
MetaWindow survives.

The saved rect is used to restore a saved window size. We need to
update this when the window is moved to a monitor with different scale,
so that if we unmaximize a window which was moved to a different
monitor while maximized (for example when unplugged) will restore to
the correct size.
https://bugzilla.gnome.org/show_bug.cgi?id=755097
When a window is moved across monitors with different scales, its
rectangle is scaled accordingly. We also need to scale the
unconstrained_rect rectangle, so that moving a window via
meta_window_move_resize() which uses the unconstrained_rect.
