The timeline base test unit is pretty slow, and under heavy load it will
tend to fail because of skipped frames. We should put it under
conditional testing and only run it if `-m slow` is passed to the test
harness.
Timeouts and idles are subject to the whims of the load of the machine
running the tests, as we found out with the new installed tests and
OSTree-based VM running the conformance test suite continuously.
We should be able to use a repaint function and a blocking loop that
either is terminated because we hit g_assert(), or because a flag gets
toggled once we know that the Stage has been at least painted once.
The currently enabled tests using clutter_stage_read_pixels() have been
updated to this approach.

If we don't have support for offscreen buffers, then there's no point in
testing FBO support in ClutterTexture — a feature that has been long
since deprecated, on a deprecated class.
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.

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.

The X11-specific windowing checks were hidden behind an #ifdef, however
if the tests were run under Wayland, they would execute uncondionally
and cause assertion failures. Fix this by also hiding them behind a
check that the current backend is indeed X11.

The CSS3 Transitions specification from the W3C defines the possibility
of using a parametrized step() timing function, with the following
prototype:
steps(n_steps, [ start | end ])
where @n_steps represents the number of steps used to divide an interval
between 0 and 1; the 'start' and 'end' tokens describe whether the value
change should happen at the start of the transition, or at the end.
For instance, the "steps(3, start)" timing function has the following
profile:
1 | x
| |
| x---|
| ' |
| x---' |
| ' |
0 |---' |
Whereas the "steps(3, end)" timing function has the following profile:
1 | x---|
| ' |
| x---' |
| ' |
x---' |
| |
0 | |
Since ClutterTimeline uses an enumeration for controlling the progress
mode, we need additional API to define the parameters of the steps()
progress; for this reason, we need a CLUTTER_STEPS enumeration value,
and a method for setting the number of steps and the value transition
policy.
The CSS3 Transitions spec helpfully also defines a step-start and a
step-end shorthands, which expand to step(1, start) and step(1, end)
respectively; we can provide a CLUTTER_STEP_START and CLUTTER_STEP_END
enumeration values for those.
It can be useful to check whether a ClutterActorIter is currently valid,
i.e. if the iterator has been initialized *and* if the actor to which it
refers to hasn't been updated.
We can also use the is_valid() method in the conformance test suite to
check that initialization has been successful, and that changing the
children list through the ClutterActorIter API leaves the iterator in a
valid state.
For now, it just generates a simple horizontal slide (by writing
to /dev/uinput) and checks that the stage gets the events at the
expected coordinates.
The test won't run if it doesn't have read/write permissions to
/dev/uinput.
It also adds OS_LINUX to config.h.
The property uses an array with the following CSS style syntax
[ top, right, bottom, left ] or
[ top, left/right, bottom ] or
[ top/bottom, left/right ] or
[ top/right/bottom/left ]

The get_distance() API uses machine integers to compute the distance;
this means that on 32bit we can overflow the integer size. This gets
hidden by the fact that get_distance() returns an unsigned integer as
well.
In reality, ClutterPath is an unmitigated mess, and the only way to
actually fix it is to break API.

Some of the Clutter code was using GL types for the primitive types
such as GLint and GLubyte and then passing these to Cogl. This doesn't
make much sense because the Cogl functions directly take native C
types. This patch just replaces them with either a native C type or a
glib type.
Some of the cogl conformance tests are trying to directly call GL for
example to test creating a foreign texture. These tests have been
changed to manually define the GL enum values instead of relying on a
GL header to define them.
This is necessary because Cogl may soon stop including a GL header
from its public headers.

It's a bit late in the game for changing the emission of the paint
signal with actors that use paint nodes - mostly because we have both
implicit paint nodes (background color, content) and explicit paint
nodes (the paint_node virtual).
When we branch for 1.12 we can revert this change.
This has been converted to a Cogl-based test in the cogl source tree
so there is no need to maintain it here anymore.

It's the conformance test suite: there's no need to namespace the files,
just like there's no need to namespace the units.
This commit does not change the Cogl tests: they will be moved to Cogl
over time, and it's easier to do if we leave them as they are.
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.
