We want the settings object to handle setting and getting the
window scaling factor value, both through backend-specific settings and
through the CLUTTER_SCALE environment variable. This means turning the
ClutterSettings:window-scaling-factor property into a readwrite one,
instead of write-only, so that ClutterStage implementations will be able
to query the window scaling factor on construction.

We do some argument validation inside _clutter_stage_do_pick(), which is
the internal version of clutter_stage_get_actor_at_pos(), but we don't
do coordinate space validation, and instead we rely on call sites doing
the right thing.
We should, instead, remove the argument validation from the internal
function, which is pointless and against the coding practices, but do
coordinate space validation internally.

...and drop these project files, as the way how the conformance
tests are built has been totally reworked. Instead, in the future,
use NMake Makefiles to build them, which will be proposed later.
Add back some deprecated and general purpose API tests. These are the
ones that were written already pretty much conforming to the GTest API
and style, and thus require minimal porting.
The current conformance test suite is suboptimal in many ways.
All tests are built into the same binary, which makes adding new tests,
builting tests, and running groups of tests much more awkward than it
needs to be. The first issue, especially, raises the bar of contribution
in a significant way, while the other two take their toll on the
maintainer. All of these changes were introduced back when we had both
Clutter and Cogl tests in tree, and because we were building the test
suite for every single change; since then, Cogl moved out of tree with
all its tests, and we build the conformance test suite only when running
the `check` make target.
This admittedly large-ish commit changes the way the conformance test
suite works, taking advantage of the changes in the GTest API and test
harness.
First of all, all tests are now built separately, using their own test
suite as defined by each separate file. All tests run under the TAP
harness provided by GTest and Automake, to gather a proper report using
the Test Anything Protocol without using the `gtester` harness and the
`gtester-report` script. We also use the Makefile rules provided by GLib
to vastly simplify the build environment for the conformance test suite.
On top of the changes for the build and harness, we also provide new API
for creating and running test suites for Clutter. The API is public,
because the test suite has to use it, but it's minimal and mostly
provides convenience wrappers around GTest that make writing test units
for Clutter easier.
This commit disables all tests in the conformance test suite, as well as
moving the data files outside of the tests/data directory; the next few
commits will re-establish the conformance test suite separately so we
can check that everything works in a reliable way.
In Cogl 1.17 libcogl-path has been split out from libcogl and now has
its own corresponding cogl-path-1.0 pkg-config file which we check for
during build configuration.
Note: this bumps the required cogl version up to 1.17.1
When the threshold-trigger-edge property was introduced in
GestureAction, it was late in the cycle and I elected to keep it
private, given the fact that nobody was subclassing GestureAction
outside of Clutter itself.
These days, people are experimenting more with the GestureAction API, so
they will need access to the various knobs that control the class
default behaviour.

Use G_GNUC_INTERNAL instead of the leading underscore, as we may make
the accessor functions public at some point. Also, clean up the
documentation.

Our clip coordinates are relative to the stage, not model-view
transformed. cogl_framebuffer_push_rectangle_clip() was accidentally
used instead of cogl_framebuffer_push_scissor_clip() when porting
to the framebuffer clip API.

Currently, if an actor with an empty paint volume is queued for redraw, it
will union in the box +0+0x1x1 to the stage clip bounds - avoid that
by special casing empty paint volumes.

I don't want to remove them altogether, but they need to be ported to a
more reliable system, otherwise they end up failing at random depending
on the whims of the compositor and the windowing system.
The PaintNode hierarchy should have the ability to retrieve the
current active framebuffer by itself, instead of asking Cogl using the
global state API.
In order to do this, we ask the root node of a PaintNode graph for the
active framebuffer. In the current, 1.x-compatibility mode we have two
potential root node types: ClutterRootNode, used by ClutterStage; and
ClutterDummyNode, used a local root for each actor. The former takes a
framebuffer as part of its construction; the latter takes the actor that
acts as the local top-level during the actor's paint sequence, which
means we can get the active framebuffer from the stage associated to the
actor.
By keeping track of the active framebuffer on the node themselves we can
drop the usage of cogl_get_draw_framebuffer() in their implementation.
The text-cache conformance test breaks because ClutterText gets a paint
without an active framebuffer associated to the ClutterStage. Keep a
fallback while we investigate the issue.
Cogl 1.18 deprecated the global clipping API in favour of the
per-framebuffer one, but since we're using the 2.0 API internally we
don't have access to the deprecated symbols any more.
This is pretty much a mechanical port for all the places where we're
still using the old 1.x API.
Instead of asking every internal user to get the stage and get the
active framebuffer from it, we can wrap it up ourselves, and do some
sanity checks as well.
Dispose() may be called more than once, so calling g_free directly
on the device name is unsafe. Instead, use g_clear_pointer() to
make sure we don't attempt to free the memory again.

When support for implicit animation of actor position was added,
the optimization for not queueing when allocating an actor back
to the same location was lost. This optimization is important
since when we are hierarchically allocating down from the top of
the stage we constantly reallocate the actors at the top of the
hierarchy back to the same place.
https://bugzilla.gnome.org/show_bug.cgi?id=719368
When the source actor potentially changes size, that shouldn't
necessarily result in the target actor being redrawn - it should
be like when a child of a container is reallocated due to changes
in its siblings or parent - it should redraw only to the extent
that it is moved and resized. Privately export an internal function
from clutter-actor.c to allow getting this right.
