This allows input methods to inject key events with specific keyval/keycode,
those events will be flagged with CLUTTER_EVENT_FLAG_INPUT_METHOD so they
won't be processed by the IM again.

If the user maps eg. Alt+F2 to a pad button, the MetaInputSettings will
send the full Alt press, F2 press, F2 release, Alt release sequence.
However the keycode corresponding to Alt is found in level 1, so the
Shift modifier gets unintendedly latched in addition to the Alt key
press/release pair.
We could probably improve keycode lookup heuristics so level=0 (and
no modifier latching) is preferred, but we can do without it altogether
for modifier keys.
If an effect is active and it overrides the paint volume, we should
always recompute the paint volume when requested and not use the
cache, since the paint volume override can change from call to
call depending on what phase of painting we are in. For instance,
if we are part way through painting effects and request the
paint volume, the paint volume should only go up to the current
effect, but in a later call to compute repaint regions, the
paint volume needs to expand to accomadate the effect.
This still involves a lot of recomputation in the case of effects -
in a later clutter version it would be worth adding an API to
allow effects to explicitly recompute and return a new the paint
volume up to the current effect as opposed to recomputing
the cached one.
Previously we were checking l->data != NULL || (l->data != NULL &&
l->data != priv->current_effect). This would continue the loop even
if l->data == priv->current_effect, since l->data != NULL, which was
not the intention of that loop.
We also don't need to check that l->data != NULL before checking if
it does not match the current_effect, since we already checked
that current_effect was non-NULL before entering the loop.
Some tablets have a noticable pointer jump on tip down/up, causing unintended
lines during drawing. Likewise, a button event may have an axis update that we
currently ignore. libinput provides tablet axis events only if no other state
changes, the client must instead get the current axis data from the tip/button
event. So let's do this, process the event axis data during tip/button as
well.
A libinput recording to reproduce is the 'dots.yml' in
https://gitlab.freedesktop.org/libinput/libinput/issues/128Fixes#289
Unfortunately XKeysymToKeycode() falls short in that it coalesces keysyms
into keycodes pertaining to the first level (i.e. lowercase). Add a
ClutterKeymapX11 method (much alike its GdkKeymap counterpart) to look up
all matches for the given keysym.
Two other helper methods have been added so the virtual device can fetch
the current keyboard group, and latch modifiers for key emission. Combining
all this, the virtual device is now able to handle keycodes in further
levels.
Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/135
A just focused ClutterInputFocus must set itself up correctly on
all situations. Refactor this into a function, so it can be used
for the case where a ClutterText gets editable while focused.
`ClutterText` painting for editable single_line_mode actors like `StEntry`
is always clipped by:
`cogl_framebuffer_push_rectangle_clip (fb, 0, 0, alloc_width, alloc_height)`
So it's difficult to get the rectangle wrong. However in cases where the
target framebuffer has changed (`cogl_push_framebuffer`) such as when
updating `ClutterOffscreenEffect` we had the wrong old value of `fb`. And
so would be clipping the wrong framebuffer, effectively not clipping at all.
Sending button events to a ClutterVirtualInputDevice, the API expects
button codes to be of the internal clutter type. The evdev
implementation incorrectly assumed it was already prepared evdev event
codes, which was not the case. Fix the evdev implementation to translate
from the internal representation to evdev before passing it along to
ClutterSeatEvdev.

Children added to a parent after that parent (or its ancestors)
have already been cloned now inherit the clone branch depth of
the parent. Otherwise `clutter_actor_is_in_clone_paint` on the child
could return FALSE when it should have been returning TRUE.
The function is intentionally provided as macro to not require a
cast. Recently the macro was improved to check that the passed in
pointer matches the free function, so the cast to GDestroyNotify
is now even harmful.

`modelview` is uninitialized and the `apply` function just multiplies it.
What we really want is to initialize `modelview` so replace `apply` with
`get`.
Who knows what bugs this may have caused...
Treat the main seat as other seats, so we don't have to handle it differently
in specific places. This was already the case before when a real device
was plugged before the startup, but not applied when hotplugging a device.
When no input devices are available on startup the device manager might be fast
enough to be constructed so that no default stage is set yet, and thus when
main seat virtual devices are created they won't have a proper stage set.
If then we plug a real device, the events that an input manager could generate
won't be associated to any stage and thus won't be processed.
We need then ensure that when we update the stage for the device manager we
(un)associate it also to the main seat devices.
In devices such as ARM boards there could be no input devices connected on
startup, leading to a crash when we try to process artificial events that
could be queued (as gnome-shell does when syncing pointer).
Those events still should refer to a device and, in case we don't have one
provided by libinput we should still return the core devices defined in the
main seat.
The fix is twofold. On one hand, it makes sense not to relate IM (nor
any other) generated events to a HW device. On the other hand, if we
are unfortunate that an IM event is in flight when we are switching
to another TTY, it may arrive at a time when the source device is no
longer existent.
Mark CAPS lock as a modifier (as it should) so that when using XKB
options to change the default behaviour of CAPS lock, the new assigned
key can by used as a sticky key as well.

Input method can inject key events, which leads to multiple reported key
press/release events for a single user action.
Ignore those events as this confuses keyboard accessibility.
And make the ClutterText-level properties independent from the input
focus, as those properties can be set anytime, not just when the
ClutterText actor is focused.

We can save an unnecessary relayout if the required size to fully draw the text
is equal to the currently allocated size after the underlying text buffer or
attributes that only affect the PangoLayout have changed.
Actor keybindings were dispatched in an earlier return path, which means
the IM doesn't get to see certain key events. Flip the order around so the
IM has an opportunity to handle all keypresses.

IF two touch devices have colliding touch point IDs they'd interfere on
the seat. To avoid this, always allocate a seat wide slot for each
device wide slot, but don't use device slots directly in the seat.
Checking correct state is responsibility of the ClutterInputFocus user, and
it is indeed possible to get a focused ClutterText while its
ClutterInputFocus didn't get itself focused (eg. lack of IM).

BTN_STYLUS3 is defined by the Linux 4.15 kernel and is sent when the
third button on a stylus is pressed. At the moment, only Wacom's "Pro
Pen 3D" has three stylus buttons. Pressing this button triggers a button
8 event to be sent under X11, so we use the same mapping here.

clutter_set_viewport always operates on the draw fb, but
mutter sometimes has an offscreen fb it uses instead.
This commit uses the non-deprecated, clutter_framebuffer_set_viewport
function, which takes an explicit fb argument.

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.
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.
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 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.

Adds a set of convenient functions that can be shared between x11 input
device backends (namely core-x11 and xi2) to control XKB accessibility
features.

Implementing keyboard accessibility in clutter means we need to be able
to notify higher layers of possible modifier masks or setting changes
(as some keyboard accessibility can be disabled or enabled by keyboard).
For this purpose, add two new signals:
ClutterDeviceManager::kbd-a11y-mods-state-changed
ClutterDeviceManager::kbd-a11y-flags-changed
https://bugzilla.gnome.org/show_bug.cgi?id=788564
Use a set of bitwise enum flags to set different keyboard accessibility
features and the necessary vfunc hooks in clutter input device so that
keyboard preferences can be passed to different input device
implementations.
The idea is to be able to configure either the clutter own
implementation of keyboard accessibility for evdev, or eventually
configure AccessX from the X11 clutter input device using the same
mechanism.
https://bugzilla.gnome.org/show_bug.cgi?id=788564
On X11, when AccessX is enabled, all X11 clients benefit from the
AccessX features, including gnome-shell/mutter, meaning that special
keys like the overview or other shortcuts are also affected.
To achieve the same in Wayland, we need to implement the same features
in clutter main rather than the Wayland backend, so that all depending
code within the compositor but also Wayland clients (which rely on the
compositor to get keyboard events) similarly benefit from the
accessibility features.
Add hooks to the clutter main loop to be able to implement such
features.
https://bugzilla.gnome.org/show_bug.cgi?id=788564
We'll need a way to trigger a bell from within clutter for keyboard
accessibility features, add the necessary hooks to be able to call a
backend bell-notify method.

The capture_into() function wrote out of bounds when capturing from a
non-origin view (not positioned at (0,0)). At the time of
implementation, this API was used to capture pixels across views into a
single data buffer, but the way it's used, and the way views may work
now, makes this impossible to do properly.
So remove the ability to capture into a pre-allocated buffer from
multiple views, and complain if the passed rectantgle overlapps with
multiple views. This removes the broken offset calculation all
together, fixing the bug motivating this change.

The reverted commit seems to cause
https://bugzilla.gnome.org/show_bug.cgi?id=787240 for some reason. Lets
be safe and revert it for now, as the code freeze is just around the
corner.
This partly (it doesn't reintroduce a whitespace issue) reverts commit
dbc63430d8.
Add API similar to clutter_stage_capture() but that draws into
externally allocated memory. It is assumed that the pixel format is
ARGB32, and the memory is structured in a way that the width of the
passed rectangle is identical to the stride divided by 4.
