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This function is deprecated and has been replaced by set_display() on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.

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.

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.
803b3bafb6 introduced a new issue for
multi touch events.
In the case where 2 touch events for 2 different touch points are
processed in the same iteration, a call to
_clutter_stage_remove_device() when processing the first event will
remove the stage setting of the InputDevice. That means Clutter will
skip the second event, because it can't find a stage to which relate
the event, so no related actor and so no emission.
To fix this we move the _clutter_stage_(add/remove)_device() calls
into the input device. This way the input device can find out exactly
when to call these functions (i.e. when no touch point were previously
active or when no touch point remain active).

ClutterTexture is full of side effects that have been picked up over the
years; they make improving ClutterTexture harder than necessary, as well
as making subclassing impossible without introducing weird behaviours in
the child classes as well.
Since Clutter 1.10 we have the ClutterImage content type, which is
side-effects free, given that it just paints texture data using the
state of the actor.
Sadly, we still have subclasses of ClutterTexture, both deprecated and
not, so we cannot deprecate ClutterTexture right out; the type and
structures will still be available, like we do for ClutterGroup, but the
whole API should be moved to the deprecated section, waiting for the
time in which we can get rid of it all.
Acquiring the Clutter lock to mark critical sections is not portable,
and not recommended to implement threaded applications with Clutter.
The recommended pattern is to use worker threads, and schedule UI
updates inside idle or timeout handlers within the main loop. We should
enforce this pattern by deprecating the threads_enter()/leave()
functions. For compatibility concerns, we need internal API to acquire
the main lock during frame processing dispatch.

It is possible that we get a DeviceChanged event for a device
that is not in the hash table yet. E.g. I've seen this when
using xrandr to change screen resolution. Prevent a crash in
this case.

When getting touch events, the device manager would try
to pass an invalid device to translate_axes().
clutter_event_set_device() will only update event->touch.device
for touch events, not event->motion.device, as used.

a touchpad.

The introspection scanner has become slightly more annoying, in the hope
that people start fixing their annotations. As it turns out, it was the
right move.
It's possible to run Clutter with the 'null' input backend, which means
that clutter_device_manager_get_default() may return NULL. In the future
we may add a default dummy device manager, but right now it's safer to
just add a simple NULL check in the places where we ask for the device
manager.
configure.ac defines XINPUT_2_2 if XI 2.2 support was found. The code
expects XINPUT_2_2 in the device manager, but HAVE_XINPUT_2_2 in the x11
backend.
On newer X servers, the latter causes a BadValue when XIQueryDevice sends a
different major/minor than gdk's device manager (gnome-control-center).

The get_geometry() implementation is broken on multi-head systems; the
only solution is to use XRandR to get the size of the CRTC that contains
the stage.
In XInput 2, the proximity events of XInput 1 have been replaced by an
axis on a valuator class. This means that, on devices that support
proximity information, for instance pens of a tablet, you will start
receiving events with the distance as an axis value - similarly to how
the pressure and tilt are presented in the API.
We still use XKeycodeToKeysym() in a fallback path in case we're not
running on a decent enough system; XKeycodeToKeysym() is deprecated as
of version 1.12 of the X server, but since I don't want to copy a bunch
of code from GDK or, god forbid, from Xlib, for a fallback path, it's
probably more reasonable to just silence the compiler warnings - at
least until we can drop all the X compatibility crap, and just use
modern, or semi-modern, API.
When handling Configure events from the X server we update the
internal copy of the window size. Unfortunately we may be updating the
wrong stage implementation because we use the one related to the event
translator (which is the first created stage).
This patch fix flickering/redrawning issues with multi-stage by
looking for the right stage implementation associated with an XEvent.

When using the Wayland backend this sets a constraint that the
CoglRenderer selects the Wayland EGL winsys.
When a Wayland compositor display is set it now also sets a constraint
that the render should use EGL because only EGL renderers will set up
the required wl_drm global object.
The X11 backend now sets the X11 constraint.

The core input devices when XInput doesn't work were being created as
generic ClutterInputDevices instead of ClutterInputDeviceX11s. This
meant the keycode_to_evdev virtual wouldn't work.

This adds a virtual function to ClutterInputDevice to translate a
keycode from the hardware_keycode member of ClutterKeyEvent to an
evdev keycode. The function can fail so that input backends that don't
have a sensible way to translate to evdev keycodes can return FALSE.
There are implementations for evdev, wayland and X. The X
implementation assumes that the X server is using an evdev driver in
which case the hardware keycodes are the evdev codes plus 8.

Since Cogl has started restricting what cogl 1.x api is exposed when
COGL_ENABLE_EXPERIMENTAL_2_0_API is defined and since we build all
Clutter internals with COGL_ENABLE_EXPERIMENTAL_2_0_API defined this
patch makes a first pass at reducing our internal use of the Cogl 1.x
api.
The most notable api that's no longer exposed to us internally is
the cogl_material_ api so this switches all Clutter internals to use the
cogl_pipeline_ api instead. This patch also makes quite a bit of
progress removing internal uses of CoglHandle although there is still
more to go.
The experimental cogl_texture_pixmap_x11_new() api was recently changed
to take an explicit context argument and return a GError on failures.
This updates Clutter's use of the api accordingly.
It should be possible to do:
clutter_stage_set_fullscreen (stage, TRUE);
clutter_actor_show (stage);
and have the stage be full screen as soon as it is shown.
Currently, we need to call clutter_actor_realize() prior to calling
set_fullscreen(), otherwise the backing X window will not be set,
and ClutterStageX11 will silently discard the change.
If set_fullscreen() was called prior to realization, ClutterStageX11
should delay setting the fullscreen hint until the realize() chain
has been successfully executed.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2515
If you execute the following sequence :
stage = clutter_stage_new ();
clutter_actor_set_size (stage, 1280, 800);
clutter_actor_realize (stage);
Then you end up creating an onscreen buffer of size 1280x800 but
ClutterStageX11 storing the stage size at 640x480.
This patch resync the 2 implementation by using the ClutterStage's
size in both classes when realizing.
