When compiling for non-glx platforms the winsys feature data array
ends up empty. Empty arrays cause problems for MSVC so this patch adds
a stub entry so that the array always has at least one entry.
Based on a patch by Ole André Vadla Ravnås
There was an array whose length was define by a static const int
variable. GCC seems to consider this a variable-length array so it
will cause warnings now that -Wvla is enabled. We might as well make
this constant a #define instead to avoid the warning.
Instead of directly manipulating GL textures itself,
CoglTexture2DSliced now works in terms of CoglHandles. It creates the
texture slices using cogl_texture_new_with_size which should always
end up creating a CoglTexture2D because the size should fit. This
allows us to avoid replicating some code such as the first pixel
mipmap tracking and it better enforces the separation that each
texture backend is the only place that contains code dealing with each
texture target.
This adds two new internal functions to create a foreign texture for
the texture 2d and rectangle backends. cogl_texture_new_from_foreign
will now use one of these backends directly if there is no waste
instead of always using the sliced texture backend.
After testing and distchecking, I verified that autoreconf can still be
used to rebuild the autotools setup.
Thanks to Javier Jardón for the second pair of eyes.
Unparented actors are owned by the Script instance, and if that goes
away then the actors go away with it. The fact that we needed an
explicit destroy() before was a hint of a memory management issue that I
blissfully - and regretfully - ignored for the sake of a passing test
suite.
They are generated at configure time, so it's a good idea to have them
in the main ignore file instead of adding them to the built ignore files
under tests.
Since we allow compiling Clutter without the XComposite extension
available, we need to protect the calls to the XComposite API with
the guards provided by the configure script.
Currently, the memory management in ClutterScript is overly complicated.
The basic design tenet should be:
- ClutterScript owns a reference on every object it creates
This allows the Script instance to reliably handle the lifetime of the
instances from creation to disposal.
In case of unmerge, the Script instance should destroy any Actor
instance, except for the Stage, and release the reference it owns. The
Stage is special because it's really owned by Clutter itself, and it
should be destroyed explicitly.
When disposing the Script itself, it should just release the reference;
any parented actor, or any InitiallyUnowned instance, will then be
managed by the parent object, as they should, while every GObject
instance will go away, as documented.

CLUTTER_EGL_BACKEND is used to define a special EGL native backend to
use and was introduced for the CEX100 EGL backend. Unfortunately
CLUTTER_EGL_BACKEND was defined to "cex100" for eglnative, which is
obviously wrong.
The paches defines the right values for CLUTTER_EGL_BACKEND for the
eglnative and cex100 flavours.
By using a new signal, ::create-surface (width, height), it should be
possible for third party code and sub-classes to override the default
surface creation code in CairoSurface.
This commit takes a bit of the patch from:
http://bugzilla.clutter-project.org/show_bug.cgi?id=1878
which cleans up CairoTexture; the idea, mutuated from that bug, is that
the CairoTexture actor checks whether the surface it has it's an image
one, and in that case it uses a Cogl texture as the backing store. In
case the surface is not an image one we assume that the surface itself
has some way of updating the GL state and flush the surface.
Always use pageflipping, but avoid full repaint by copying back dirty
regions from front to back. Additionally, we dealy copying back until
we're ready to paint the new frame, so we can avoid copying areas that
will be repainted anyway.
This is the least amount of copying per frame we can get away with at all
and at the same time we don't have to worry about stalling the GPU on
synchronized blits since we always pageflip.
When we don't use a window system drawable, we can't query the color
masks at context initialization time. Do it lazily so we're sure to have
a current context with a valid framebuffer.
We need to make sure that redraws queued for actors on a stage are for
actors actually in the stage. So in clutter_actor_unparent() descend
through the children and remove redraws. Just removing the actor itself
isn't good enough since an entire hierarchy can be removed from the
stage without breaking it up into individual actors.

This is based on an original patch from Owen Taylor who debugged the
root cause of this bug; thanks.
In the case that an unclipped redraw of an actor is queued after a
clipped we should update any existing ClutterStageQueueRedrawEntry
so entry->has_clip = FALSE and free the previous clip.
Re-order the units into a sensible list, with basic tests at the
beginning, and per-class tests at the end - with Cogl last.
Also, start renaming the unit functions from test_<foo> to <foo>,
so that the executable wrappers and the reports have sensible names.
The TODO() macro for adding new tests to the test suite has always meant
to be implemented like the TODO block in Test::More, i.e. a test that is
assumed to fail, and which warns if it unexpectedly succeeds.
Since GTest lacks the expressivity of Test::More, the implementation
just verifies that the tests marked as TODO actually fail, and will fail
if they happen to succeed - at which point the developer will have to
change the macro to SIMPLE or SKIP.
Even if gtester-report doesn't use that information (yet), we should
store the revision of Clutter that generated the report, and the date in
which the test suite was ran.
Instead of trying to run ./test-conformance with the -l option to
generate a list of available tests it now runs sed on the
test-conform-main.c file instead. Running the generated executable is
a pain for cross-compiling so it would be nice to avoid it unless it's
absolutely necessary. Although you could tell people who are cross
compiling to just disable the conformance tests, this seems a shame
because they could still be useful along with the wrappers for example
if the cross compile is built to a shared network folder where the
tests can be run on the actual device.
The sed script is a little more ugly than it could be because it tries
to avoid using the GNU extensions '\+' and '\|'.
The script ends up placing restrictions on the format of the C file
because the tests must all be listed on one line each. There is now a
comment to explain this. Hopefully the trade off is worth it.

Instead of using the allocation-changed signal, use the queue-relayout
signal on the source to queue a relayout on the actor to which the
BindConstraint has been attached to.
The ::allocation-changed signal is not always enough, given that a
BindConstraint can use the position as well as the size of an actor to
drive the allocation of another; in this regard, it's much similar
to a ClutterClone, which requires a notification on every change, even
potential, and not just real ones, given the short-circuiting done
inside ClutterActor.
