Using 800x600 as minimum logical size is very 4:3 thinking, while a lot of
modern devices are 16:9. The specific reason for this commit is to allow
1.5 scaling at mini-laptops (clamshell devices) with e.g. a 5.5"
1280x720 screen. Given that this device has a keyboard, one obviously
is not holding it very close to ones eyes and at 220 dpi that means the text
is too small at scale 1.0. For one real world example of such a device see:
https://en.wikipedia.org/wiki/GPD_Winhttps://bugzilla.gnome.org/show_bug.cgi?id=792765
This function returns TRUE if there is any preedit going on. This method
will be useful in gnome-shell where similar checks are performed on
StIMText actors.
Offer the text-input interface global, so it can be used by clients. The
MetaWaylandSeat will also let MetaWaylandTextInput intercept key events
before the keyboard interface handles those.
This is the implementation of the internal text-input protocol that will
be used to communicate IMs (to be implemented by gnome-shell) with clients.
The text_input protocol has its own focus expressed through enter/leave
events, that will typically follow the keyboard's.
The client will be able to communicate its current status (eg. focus state,
cursor rectangle in surface coordinates, text surrounding the cursor
position, ...) and will receive commands from the compositor (eg. preedit
text, committing a string, ...).
Whenever there is an active input method, the compositor will route key
events directly through it. The client will not receive wl_keyboard
events if the event is consumed by the IM.
ClutterInputFocus is an abstract object to be subclassed by UI actors and
the wayland interface and represents the user of an input method. It
represents the current focus of the input method, so all emitted signals
and public API hooks are expected to be called when the input method is
currently interfacing with the input focus.
ClutterInputMethod is an abstract class (to be implemented in the upper
layers) that represents the input method itself. Besides focus management
itself, all public API calls that would be called by the subclasses are
delivered through the current input focus.
Issuing a shortcut inhibit request for a surface without a window set
will lead to a crash when trying to show the shortcut inhibitor dialog.
In such a case, it's safer to deny the request.

The events might fall through if there's no corresponding active
pointer/keyboard/touch interface. Barring bugs this should be safe to do,
just a bit wasteful.
Libinput shall report those as having slot=-1, which gets mistakenly
translated into the special "NULL" ClutterEventSequence. Making those
events get a non-NULL sequence will make single touch devices work.
https://bugzilla.gnome.org/show_bug.cgi?id=792005
We might receive touch events for unknown touch points, for example
when starting mutter while touching the screen (resulting in no
touch-down event ever being received). Avoid crashing when this happens
by just dropping these events on the floor.

When maximizing a window, the previous location is saved so that
un-maximize would restore the same original window location.
However, if a Wayland client starts with a window maximized, the
previous location will be 0x0, so if we have to force placement in
xdg_toplevel_set_maximized(), we should update the location as well so
that the window is placed on the right monitor when un-maximizing.
For that purpose, add a new flag to force the update of the window
location, and use that flag from xdg_toplevel_set_maximized().
https://bugzilla.gnome.org/show_bug.cgi?id=783901
Wayland clients know their size better, so for Wayland we'd rather not
try to resize the client on un-maximize, but for this to work we need a
new MetaMoveResizeFlags.
https://bugzilla.gnome.org/show_bug.cgi?id=783901
When closing a window and showing a new one, the new one may not be
granted input focus until it gets a buffer on Wayland.
If another window is chosen to receive focus and raised on top of stack,
the newly mapped window is focused but placed underneath that other
window.
Meaning that for Wayland surfaces, we need to defer adding the window to
the stack until we actually get to show it, once we have a buffer
attached.
Rather that checking the windowing backend prior to decide if a window
is stackable or not, introduce a new vfunc is_stackable() which tells
if a window should be added to the stack regardless of the underlying
windowing system.
Also add meta_window_is_in_stack() API rather than checking the stack
position directly (replacing the define WINDOW_IN_STACK only available
in stack.c) and remove a window from the stack only if it is present
in the stack, so that the test in meta_stack_remote() becomes
irrelevant.

Wayland clients using the wl_shell interface were never receiving mouse
input. It meant they also couldn't be raised with a click.
This was because the call to meta_wayland_surface_set_window for wl_shell
surfaces did nothing while surface->window == window already. As such, it
never called clutter_actor_set_reactive() and the wl_shell window remained
a non-reactive actor.
Just make sure surface->window isn't already set before calling
meta_wayland_surface_set_window so it can actually do what it's meant to.

The device orientation coming out of iio-sensor-proxy defines upright/normal
as the direction in which the picture is displayed on the LCD panel without
any rotation. This is necessary for accelerometer rotation to work properly
in desktop environments which are not aware of panel-orientation issues.
This means that we need to correct the logical-monitor-config / user-visible
rotation for the panel-orientation when we get rotation info from
iio-sensor-proxy.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Just like we swap the x and y resolution of the monitor modes when
the panel-orientation requires 90 or 270 degree rotation to compensate,
we should do the same for the width and height in mm of the monitor.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
If a monitor's max resolution is a portrait resolution, then assume it is
a native portrait monitor and add portrait versions of the common modes.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Even if the logical_monitor config does not have an active transform,
we might still be doing a transform under the hood to compensate for
panel-orientation. Check for this and fall back to the sw cursor if this
is the case.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
If a LCD panel has a non normal orientation (mounted upside-down or 90
degrees rotated) then the kernel will report touchscreen coordinates with
the origin matching the native (e.g. upside down) coordinates of the panel.
Since we transparently rotate the image on the panel to correct for the
non normal panel-orientation, we must apply the same transform to input
coordinates to keep the aligned.
https://bugzilla.gnome.org/show_bug.cgi?id=782294
Some x86 clamshell design devices use portrait tablet LCD panels while
they should use a landscape panel, resoluting in a 90 degree rotated
picture.
Newer kernels detect this and rotate the fb console in software to
compensate. These kernels also export their knowledge of the LCD panel
orientation vs the casing in a "panel orientation" drm_connector property.
This commit adds support to mutter for reading the "panel orientation"
and transparently (from a mutter consumer's pov) fixing this by applying
a (hidden) rotation transform to compensate for the panel orientation.

If input happens to be grabbed somewhere along the shell, and ungrabbed
while a touch operation is ongoing, the wayland bits will happily start
sending wl_touch.update events from an undeterminate point, without
clients having ever received wl_touch.down for that id.
Consider those touches grabbed for the entirety of their lifetime, if
wl_touch.down wasn't received by the client, no other events will.

When a Wayland client issues a shortcut inhibit request which is granted
by the user, the Super key should be passed to the surface instead of
being handled by the compositor.

When capture_view* functions are called with the paint flag set
to TRUE, we need to setup the framebuffer, however this was
happening after setting up the viewport, while the viewport
needs the framebuffer to be valid when calling cogl_set_viewport.

On VT switch, the xkb state layout index is lost and reset to the first
group, so if the first layout is not the last one being used, the xkb
state used in both meta-wayland-keyboard.c and clutter/evdev will be
desynchronized with the keyboard source indicator in the gnome-shell UI.
Save the effective layout chosen along with the seat so it can be
restored when reclaiming devices.
Use the saved layout index from the clutter/evdev's seat to restore the
layout in meta-wayland-keyboard, so that switching VT doesn't reset the
layout and causes further discrepancies with the layout indicator in the
gnome-shell UI.

The reason why multiple keycodes could be mapped to a single keysym was
to support having both KEY_FAVORITES and KEY_BOOKMARK map to
XF86Favorites. However, iterating through all layout levels adding all
key codes has severe consequences on layouts with levels that map
things like numbers and arrow. The result is that keybindings that
should only have been added for keycodes from the first level, are
replaced by some unexpected keycode where the same keysym was found on
another level.
An example of this is the up-arrow key and l symbol. Normally you'd find
both the up-arrow symbol and the l symbol on the first level and be done
with it. However, on the German Neo-2 layout, layout level 4 maps the
KEY_E to the l symbol, while layout level 4 maps KEY_E to up-arrow.
Which ever gets to take priority is arbitrary, but for this particular
case KEY_E incorrectly mapped to up-arrow instead of the l symbol,
causing the keyboard shortcut Super+l, which would normally lock the
screen, to trigger the workspace-up (Super+up-arrow) key binding.

This protocol is limited to Xwayland only and is not visible/usable by
any other client.
Mutter uses the following mechanisms to determine if an X11 client
should be granted a grab:
- is "xwayland-allow-grabs" set?
- if set, is the client blacklisted?
- otherwise, has the client set the X11 window property
_XWAYLAND_MAY_GRAB_KEYBOARD on the window using a client message?
- if not, is it a client white-listed either via the default system
list or the settings "xwayland-grab-access-rules"?
https://bugzilla.gnome.org/show_bug.cgi?id=783342
Add a new client message "_XWAYLAND_MAY_GRAB_KEYBOARD" that X11 clients
can use to tell mutter this is a well behaving X11 client so it may
grant the keyboard grabs when requested.
An X11 client wishing to be granted Xwayland grabs by gnome-shell/mutter
must send a ClientMessage to the root window with:
- message_type set to "_XWAYLAND_MAY_GRAB_KEYBOARD"
- window set to the xid of the window on which the grab is to be issued
- data.l[0] to a non-zero value
Note: Sending this client message when running a plain native X11
environment would have no effect.

MetaWindowXwayland derives from MetaWindowX11 to allow for some Xwayland
specific vfunc that wouldn't apply to plain X11 windows, such as
shortcut inhibit routines.
