If we pass TRUE for x_align and FALSE for y_align, the full available
width should be passed to clutter_get_preferred_height, and the same
should be true in the other dimension.

Instead of directly accessing the instance fields. This removes a
compiler warning after the constification of g_get_prgname(), and it
seems to me to be generally more correct.
Instead of using a custom apply_transform(), paint(), and pick()
implementations, we can simply apply a transformation to the children of
a ScrollActor.

As wayland-client.h and wayland-server.h can't be included together,
split the Wayland backend file into clutter-backend-wayland.h, which
only defines the types, and clutter-backend-wayland-priv.h, which
actually uses the Wayland client types.

The definition of wl_display differs between Wayland clients and
servers, and it's unsafe to include both wayland-client.h and
wayland-server.h at the same time. Fudge around this by making the
compositor public API use void * rather than struct wl_display *.

This function is deprecated and has been replaced by set_display() on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

Being able to set a marker at a normalized point on a timeline, instead
of using a specific time, is a nice fit with the current Timeline class
API.

If anything in the system changes the config for fontconfig then an
XSetting will be set to record the last timestamp of the config file.
This is presumably so that applications can be notified that it has
changed and can reload the configuration. However once this setting is
set it will remain set for the lifetime of the X server. This causes
Clutter to handle the setting during the initialisation of the
backend. Previously this would cause problems because Clutter would
end up creating the default PangoFontMap before the backend has
created the CoglContext. The PangoFontMap would in turn cause the
default CoglContext to be created. Clutter will then later create its
own CoglContext which means there will be two and the first one will
be leaked. Cogl currently can't really cope with multiple contexts
being created so it falls apart.
This patch fixes it to skip reloading the config for fontconfig if
there isn't a default font map yet. The config will presumably
naturally be read with the latest values when it is finally created
anyway so it doesn't need to be read immediately.

New experimental API is added to allow changing the way that redraws
are timed for a stage to include a "sync delay" - a period after
the vertical blanking period where Clutter simply waits for updates.
In detail, the algorithm is that when the master clock is restarted
after drawing a frame (in the case where there are timelines running)
or started fresh in response to a queued redraw or relayout, the
start is scheduled at the next sync point (sync_delay ms after the
predicted vblank period) rather than done immediately.

In commit 8f4e39b6d7 the Wayland code was updated to use the new
xkbcommon API. This involved changing the common XKB code shared with
the evdev input backend. However the evdev input backend was not
modified so it wouldn't compile. This patch just makes a minor change
to update it.

Use the buffer_age extension when available to recycle backbuffer contents
instead of blitting from the back to front buffer when doing clipped redraws.
The picking is now done in a pixel that is going to be repaired during the next
redraw cycle for non static scences.
This should improve performance and avoid tearing.

This allows us to report to the backend that the stage's back buffer has been trashed
while handling picking. If the backend is keeping track of the contents of back buffers
so it can minimize how much of the stage is redrawn then it needs to know when we do pick
renders so it can invalidate the back buffer.

The behaviour imitates GtkEntry and ignores attributes from markup because Pango
barfs on invalid markup. Also add an example to the text-field interactive test.

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.

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.

Instead of placing the whole body of the function inside an if block,
let's make it clear what each part of the function does. Also, add more
comments.
GLib 2.36 will deprecate g_type_init() in favour of automatic
initialization through a constructor function. We need to add the
version check to avoid a compiler warning.
When setting an explicit transform with clutter_actor_set_transform()
and a non (0,0) pivot-point, clutter_actor_apply_transform() will fail
to roll back the pivot-point translation done before multiplying the
transformation matrix due to the "out:" label being slightly misplaced
in clutter_actor_real_apply_transform().
This works properly:
clutter_actor_set_pivot_point (actor, 0.5, 0.5);
clutter_actor_set_rotation_angle (actor, CLUTTER_Z_AXIS, 30);
This results in the actor being moved to the pivot-point position:
clutter_actor_set_pivot_point (actor, 0.5, 0.5);
clutter_matrix_init_identity(&matrix);
cogl_matrix_rotate (&matrix, 30, 0, 0, 1.0);
clutter_actor_set_transform (actor, &matrix);
This also add a conformance test checking that even when using a
pivot-point, no matter how a rotation is set the resulting
transformation matrix will be the same.
