When an application sets the scaling factor manually we should mark it as fixed
and not override it when the xsettings change. This matches GDKs behaviour.
In order for this to work we cannot use the same path when setting the value
internally so introduce a _clutter_settings_set_property_internal and use it
for that.

Until now, touch events sort of rely on XI_Enter/XI_Leave events accompanying
the pointer emulating touch in order to have a stage set on the device, These
events won't happen though if it's not a pointer emulating touch which happens
on the stage, causing touch events to be ignored.
Fix this by ensuring that the input device has a stage on XI_TouchBegin itself,
but only if it's not already set, so we don't possibly steal touch events to
an already interacting stage.

The coordinates translated by the XI2 device manager were being clamped using
the X window size kept by StageX11. However, when the stage is fullscreen,
that size is not updated to the screen size, but kept the same in order to
allow going back to it when the stage goes out of fullscreen.

All backends follow the same pattern of queueing events first in
ClutterMainContext, then copying them to a ClutterStage queue and
immediately free them. Instead, we can just pass ownership of events
directly to ClutterStage thus avoiding the allocation and copy in
between.

We should use the Xkb API to query the direction of the key map,
depending on the group. To get a valid result we need to go over
the Unicode equivalents of the key symbols for each group, so we
should cache the result.
The code used to query and cache the key map direction is taken
from GDK.

Currently clutter_device_manager_xi2_get_core_device always
does a round trip to query the client.
So avoid that by caching the client pointer and only update it when the
xi devices change.

Due to the way add_device() invariably adds to the master/slave device
lists, while keeping ClutterInputDevices 1:1 with device IDs, it may
leave invalid pointers in the list if add_device() is called multiple
times for the same device ID. There are two situations where this may
happen:
1) If devices are disabled and later enabled: devices are added invariably
to the master/slave lists on constructed(), but then on XIDeviceEnabled
they'd get added yet again.
2) Racy cases where the ClutterDeviceManager is created around the same time
XIHierarchyEvents are sent. When getting the XIDeviceInfo on constructed(),
these devices may already appear as enabled, even though XIDeviceEnabled
is seen through XIHierarchyEvents processed in the event loop sortly after.
This last case can be seen when starting gnome-shell on a different tty,
and entering in the one it's been spawned on, clutter initialization
happens around the same time devices are added back because of the tty
switch, and multiple extra ClutterInputDevices are created.

If we get a change in the window scaling factor we want to resize the
backing store of each stage, so we use the notification on the
ClutterSettings:window-scaling-factor property to do so.

The state that the X server sends for button events, by specification,
contains the button state before the event. We need to synthesize in
the result of the event in order to determine what the current button
state is.

XFixesShowCursor / XFixesHideCursor does not actually take the suppled
window argument into account -- the effect is actually global. Use
XDefineCursor instead.

For some XI2 we do not have a Stage associated to the event window.

On high DPI density displays we create surfaces with a size scaled up by
a certain factor. Even if the contents stay at the same relative size
and position, we need to compensate the scaling both when changing the
surface size, and when dealing with input.

When talking to other applications or serializing the modifier
state (and in particular when implementing a wayland compositor),
the effective modifier state alone is not sufficient, one needs
to know the base, latched and locked modifiers.
Previously one could do with backend specific functionality
such as clutter_device_manager_evdev_get_xkb_state(), but the
problem is that the internal data structures are updated as
soon as the events are fetched from the upstream source, but
the events are reported to the application some time later,
and thus the two can get out of sync.
This way, on the other hand, the information is cached in the
event, and provided to the application with the value that
was current when the event was generated.

This removes a bit of work that we have to do for every device, and makes it
easy for mutter to patch out parts of the event mask it doesn't want.

Since XIQueryVersion, the bad API that it is, chooses the first client
version that it gets, we need to ensure that we pass XIQueryVersion the
new XI2.3 version, knowing fully well that Clutter won't be confused
by the new features.

The X server should fill in the minor version that it supports in the
case where it only supports the older version. We should not get a
BadRequest or fail the version check if we pass something higher.

This function is deprecated and has been replaced by set_display() on
the renderer. This is done in the get_renderer() vfunc of both the x11
and gdk backends already.
Actually cogl_xlib_set_diplay() is now a no-op and can be safely removed.
https://bugzilla.gnome.org/show_bug.cgi?id=687652
As x11 considers num lock and scroll lock to be modifiers, code that
checks for an exact modifier combination will fail if naively done when
num lock or scroll lock are turned on. Applications that want to ignore
these modifiers will need to use XKB to manually mask out the modifier
state.
As it is very unlikely that applications will want to care about the
state of num lock or scroll lock for key press/key release events, mask
out the num lock and scroll lock keys automatically.

This has been disabled since February 2008, on the grounds that XFixes
didn't work reliably for hiding cursors. This has almost certainly been
fixed then and seems to work entirely reliably across a number of X
servers released in the past few years, and is definitely better than a
1x1 black dot for a cursor.
Helpfully though, where the spec states that the cursor will be hidden
when inside the specified window or one of its children, it actually
only uses the window to look up the Screen, and hides the cursor across
the entire Screen. So, when using this, we also need to track crossing
events.
If it's still broken, this needs to be fixed in the X server.

Otherwise, we'll have incorrect scrolling when we switch hardware
devices without switching virtual devices. For example, on a ThinkPad,
scroll using the touchpad, move the eraser mouse, and then scroll again:
the deltas will be wrong. This also matches what GTK+ does.
https://bugzilla.gnome.org/show_bug.cgi?id=689258
When the last touch has been released the stage on the
corresponding master device (eg. the virtual core pointer) is set
to NULL and no mouse events can be delivered until an ENTER event
has occurred and the stage pointer restored.
This is due to the fact that the master devices can send both
touch events and mouse events, forwarding events coming from the
attached slave devices.
To restore delivery of mouse events we need to ensure that the
stage is set on each ButtonPress, ButtonRelease and Motion event
coming from master devices.

The ClutterEventSequence structure is a fully opaque type; on X11, it is
just an unsigned integer that gets converted into a pointer, but in the
future it may become a fully fledged data structure.
Obviously, we cannot tell people to just dereference the pointer into an
integer in order to use it, and still retain the ability to change the
type; for this reason, we need a proper accessor function to convert the
EventSequence into a touch detail, to be used with the XInput API.
