If we allow content repeats on the texture nodes, then we need to use
the "automatic" wrap mode for the texture layer in the pipeline, instead
of the clamp-to-edge one.

This reverts commit 6dd9da05c7.
Windowing system features we need are not mapped on cogl_has_feature().

Cogl (as of 0b2b46ce) now only sets the shell surface as toplevel when
the CoglOnscreen is shown.
Without calling wl_shell_surface_set_toplevel the compositor will not
know what role to give to the compositor and thus the stage will not
appear.
When we look to support multiple roles / foreign surfaces we will need
to revisit this call and ensure we only call it when we are working in
the default case.

Since Cogl also polls on this file descriptor we can get into situations
where our event source is woken up to handle events but those events
have instead been handled by Cogl resulting in the source sitting in
poll().
We can safely rely on Cogl to handle the polling on the event source and
to dispatch those events.

When the cursor visibility changes, we have to relayout the ClutterText
actor instead of just redrawing it - as the cursor changes the
PangoLayout size, a size request cycle is needed.

While we still don't want to perform implicit transitions on unmapped
actors, we can relax the requirement on having been painted once; the
was_painted flag was introduced to avoid performing implicit transitions
on the :allocation property, but for that we can use the
needs_allocation flag instead, as needs_allocation will be set to FALSE
when we have been painted as well.
Thus, we retain our original goal of not having actors "flying" into
position on their first allocation, without the side effect of
preventing animations when emitting the ::show signal.
When setting the font using clutter_text_set_font_description(), the
font settings on a ClutterText actor can be reset when there is a dpi
changes signaled by the backend.

1ddef9576d87c98fafbcefe3108f04866630c2cd had its logic the
wrong way round, a gesture should begin as soon as the requested number
of touchpoints is reached. Correcting this fixes tap events

When we changed the MetaGroup to handle internal effects, we updated
has_effects(), but forgot to fix the equivalent has_constrains() and
has_actions() method.
Now, if we clear the constraints or the actions on an actor, and we
call has_constraints() or has_actions(), we get an false positive.
When using a ClutterOffscreenEffect, the size of the offscreen buffer
allocated to perform the effect is currently computed using the paint
volume of the actor it's attached to and in the case the paint volume
cannot be computed, the effect falls back to using the stage's size.
If you scale an actor enough so its paint volume is much bigger that
the size of the stage, you can end up running out of memory (which
leads to your application crashing).

The "should this implicit transition be skipped" check should live into
its own function, where we can actually explain what it does and which
conditions should be respected.
Instead of just blindly skipping actors that are unmapped, or haven't
been painted yet, we should add a couple of escape hatches.
First of all, we don't want :allocation to be implicitly animated until
we have been painted (thus allocated) once; this avoids actors "flying
in" into their allocation.
We also want to allow implicit transitions on the opacity even if we
haven't been painted yet; the internal optimization that we employ in
clutter_actor_paint() and skips painting fully transparent actors is
exactly that: an internal optimization. Caller code should not be aware
of this change, and it should not influence code outside of ClutterActor
itself.
The rest of the conditions are the same: if the easing state's duration
is zero, or if the actor is both unmapped and not in a cloned branch of
the scene graph, then implicit transitions are pointless, as they won't
be painted.

This should actually ensure that the calculations of the Z translation
for the projection matrix is resolved to "variable * CONSTANT". The
original factors are left in code so it's trivial to revert to the
trigonometric operations if need be, even without reverting this commit.
The ClutterActor::paint signal is deprecated, and connecting to it even
to get notifications will disable clipped redraws because of violations
of the paint volume.
The only actual valid use case for notifications of a successful frame
is on the ClutterStage, so we should add new (experimental) API for it,
so that users can actually subscribe to it — at least if you're writing
a compositor.
Shoving a signal in a performance critical path is not an option, and
I'm not sure I want to commit to an API like this yet. I reserve the
right to revisit this decision in the future.

Currently, clutter_canvas_set_size() causes invalidation of the canvas
contents only if the newly set size is different. There are cases when
we want to invalidate the content regardless of the size set, but we
cannot do that right now without possibly causing two invalidations,
for instance:
clutter_canvas_set_size (canvas, new_width, new_height);
clutter_content_invalidate (canvas);
will cause two invalidations if the newly set size is different than
the existing one. One way to work around it is to check the current
size of the canvas and either call set_size() or invalidate() depending
on whether the size differs or not, respectively:
g_object_get (canvas, "width", &width, "height", &height, NULL);
if (width != new_width || height != new_height)
clutter_canvas_set_size (canvas, new_width, new_height);
else
clutter_content_invalidate (canvas);
this, howevere, implies knowledge of the internals of ClutterCanvas,
and of its optimizations — and encodes a certain behaviour in third
party code, which makes changes further down the line harder.
We could remove the optimization, and just issue an invalidation
regardless of the surface size, but it's not something I'd be happy to
do. Instead, we can add a new function specifically for ClutterCanvas
that causes a forced invalidation regardless of the size change. If we
ever decide to remove the optimization further down the road, we can
simply deprecate the function, and make it an alias of invalidate()
or set_size().
Since we are trying to eliminate the ClutterGeometry type, we should
replace the only entry point still using it: the ::cursor-event signal
of ClutterText.
Instead of passing the cursor geometry, we should add an accessor
function.
The combination of signal and getter for the cursor geometry means that
we can deprecate ClutterText::cursor-event, and mark it for removal in
Clutter 2.0.
