c185a17783 event: Add pinch/swipe gesture event types and structs
We now have ClutterTouchpadPinchEvent and ClutterTouchpadSwipeEvent,
each bringing the necessary info for the specific gesture. Each
of these events is defined by begin/update/end/cancel phases.

These events have been also made to propagate down/up the pointer
position, just like scroll and button events do.

253292802c Drop the UProf dependency
Nobody has been compiling Clutter with profiling enabled in a long time.

UProf itself hasn't been updated in 5 years, and it still depends on
deprecated components like dbus-glib, with no port to GDBus in sight.

The profiling code was moderately useful in the past, but these days
it's probably better to profile Cogl than Clutter itself; timing
information can be extracted by the timestamp on each diagnostic message
that is now available by default in the CLUTTER_NOTE macro, and we can
add ad hoc counters where needed.

46877cc2bd actor: Create a PangoContext per actor
For a variety of complicated reasons, ClutterText currently sets fields
on the PangoContext when creating a layout. This causes ClutterText to
behave somewhat erratically in certain cases, since the PangoContext is
currently shared between all actors.

GTK+ creates a PangoContext for every single GtkWidget, so it seems like
we should do the same here.

Move the private code that was previously in clutter-main.c into
clutter-actor.c and clean it up a bit. This gives every actor its own
PangoContext it can mutilate whenever it wants, at its heart's content.

14d28e7908 main: Don't update the PangoContext in clutter_set_font_flags
clutter_set_font_flags already calls clutter_backend_set_font_options,
which emits a signal which our PangoContext listens to, so this is just
duplicate and unneeded code.

d7b183a4e3 clutter-main: start mainloop timer on clutter_init()
By creating and starting the timer on clutter_main() an assumption is made
that that is how the main loop will be run for all clutter applications.
With more and more applications moving to GApplication, this assumption no
longer holds true.

Moving to clutter_init() means we are starting the timer earlier than we
should, and by not stopping it when the main loop quits we are taking a
measure that is later than we should. I believe it is safe to consider
those are close enough to the actual beginning and quitting of the main
loop in practice.

e70a0109f2 Avoid needless event copies when queueing from a backend to a stage
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.

70292672c4 Add API to install an event filter
This adds clutter_event_add/remove_filter which adds a callback
function which will receive all Clutter events just before the event
signal is emitted for them. The event filter will be invoked
regardless of any grabs or captures. This will be used by Mutter which
wants to access the events at a lower level then the event bubbling
mechanism. It needs to see all mouse motion events even if there is a
grab in place.

bbb54f1aed clutter: Prefer the X11 backend to the Wayland one
If clutter is built with both X11 and Wayland support, prefer the
(more complete for now) X11 backend. This matches GTK+'s current
ordering.

This allows distributions to ship a clutter version with both backends
built, and using an envvar to switch to the wayland backend and test
applications.

In the future, applications would be able to choose which backend
they prefer and in which order.

cea8ea06f3 events: Make _clutter_process_event() reentrant
The _clutter_process_event() function may get called while already
servicing a _clutter_process_event() invocation (eg. when generating
ENTER events before emitting TOUCH_BEGIN).

In these cases clutter_get_current_event() would return NULL after
the inner call to _clutter_process_event() has finished, thereafter
making the current event inaccessible during the remaining portion
of the outer event emission.

By stacking the current events in ClutterMainContext instead of
simply replacing them we do not lose track of the real current event.

Also update clutter_get_current_event_time() to be consistent from a
reentrancy perspective.

0da0e5122e main: Do not release the lock if it hasn't been acquired
On various systems, trying to release a mutex that hasn't been acquired
will result in a run-time error.

In order to avoid this, we trylock() the Big Clutter Lock™ and
immediately unlock() it, regardless of the result; if the lock was
already acquired, trylock() will immediately fail, and we can release
it; if the lock was not acquired, trylock() will succeed, and we can
release the lock immediately.

This is necessary to maintain binary compatibility and invariants for
Clutter applications doing:

  clutter_init()
  clutter_threads_enter()
  ...
  clutter_main()
  ...
  clutter_threads_leave()

instead of the correct:

  clutter_init()
  clutter_threads_enter()
  ...
  clutter_threads_leave()
  clutter_main()
  clutter_threads_enter()
  ...
  clutter_threads_leave()

With Clutter ≥ 1.12, the idiomatic form is:

  clutter_init()
  ...
  clutter_main()

given that the public Big Clutter Lock™ acquire/release API has been
deprecated, and nobody should take the lock outside of Clutter itself.

d6a0f7eb61 input-device: don't reset a device's stage until all touch points are gone
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).

bubbling/captured sequences on the actor located under the pointer and

0e4c6d0a87 Deprecate clutter_threads_enter()/leave()
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.

prior to the stages update phase of the frame processing.

As a bonus, we can also add a flag that causes adding a repaint function

7d4a9c6f1e Add diagnostic mode
GLib has a "diagnostic mode" switch that can be checked to enable debug
messages on deprecated properties and signals, as these are purely
run-time constructs, and as such cannot be caught by compiler warnings.
The diagnostic mode is toggled by a simple environment variable, and
can be used to ease porting of application code.

We can use something similar to mark deprecated virtual functions and
other run-time constructs; to avoid collisions, we should use our own
environment variable, CLUTTER_ENABLE_DIAGNOSTIC.
