Since an actor can only be parented to one container we don't need
the extra complications of maintaining a list of ChildMeta objects
attached to an actor in the default implementation of the Container
interface.
ClutterBehaviourPath has been changed and ClutterBehaviourBspline has
been removed; now we use ClutterPath everywhere we need to describe a
path. This warrants a chapter in the migration guide.
Instead of using ClutterActor for the base class of the Stage
implementation we should extend the StageWindow interface with
the required bits (geometry, realization) and use a simple object
class.
This require a wee bit of changes across Backend, Stage and
StageWindow, even though it's mostly re-shuffling.
First of all, StageWindow should get new virtual functions:
* geometry:
- resize()
- get_geometry()
* realization
- realize()
- unrealize()
This covers all the bits that we use from ClutterActor currently
inside the stage implementations.
The ClutterBackend::create_stage() virtual function should create
a StageWindow, and not an Actor (it should always have been; the
fact that it returned an Actor was a leak of the black magic going
on underneath). Since we never guaranteed ABI compatibility for
the Backend class, this is not a problem.
Internally to ClutterStage we can finally drop the shenanigans of
setting/unsetting actor flags on the implementation: if the realization
succeeds, for instance, we set the REALIZED flag on the Stage and
we're done.
As an initial proof of concept, the X11 and GLX stage implementations
have been ported to the New World Order(tm) and show no regressions.
The old code checked whether the property began with 'signal-' and
then checked for 'signal-swapped' and 'signal-after'. This prevented
you from animating a property called for example 'signal-strength'.
The check for the prefix is now in a separate function which also adds
a 'signal-swapped-after' prefix for completeness.

The column names are optional - ClutterModel will use the GType name
if there is no user-specified column name. Hence, the ::finalize vfunc
should not try to free an empty column names vector.

The test-script.json UI definition still used old types, like
ClutterLabel and ClutterCloneTexture. It should move to the classes
that have replaced them.
The default floating point type for JSON is double precision; this means
that we need to conver to single precision when setting a property with
type G_TYPE_FLOAT.
We need to test that the depth sorting of ClutterGroup works correctly
in case we wish to change the data structure that stores the children,
and do so without changing the default behaviour.
The get_type() function for ClutterInterval is missing from the
known GObject types, so gtk-doc doesn't know that it has to
introspect it for hierarchy, properties and signals.
Currently, to update a property inside an animation you have to
get the interval for that property and then call the set_final_value()
method.
We can provide a simpler, bind()-like method for the convenience of
the developers that just validates everything and then calls the
Interval.set_final_value().
Right now we just check for a NULL stage before calling glXMakeCurrent().
We can, though, get a valid stage without an implementation attached to
it while we are disposing a stage after a CLUTTER_DELETE event, since the
events processing is performed on a vblank-locked basis.
ClutterClone bases its preferred size on the preferred size of
the source actor, so it needs to invalid its cached preferred
size when the preferred size of the source actor changes.
In order for this to work, we need to have notification when
the size of the source actor changes, so add a ::queue-relayout
signal to ClutterActor.
Then connect to this from ClutterClone and queue a relayout
on the clone when a relayout is queued on the source.

This reverts commit 3c47a3beb5.
Of course I remembered just after pushing the patch why we hadn't done
this before :-) If you look in the glsl spec:
http://www.khronos.org/registry/gles/specs/2.0/es_full_spec_2.0.24.pdf
Section 3.7.10 Texture Completeness and Non-Power-Of-Two Textures
you can see GLES 2.0 doesn't support mipmaps for npot textures.
There is possibly some way we could support this in Cogl but at least
it's not as simple as or-ing in the feature flag, sadly.
The core GLES2 API supports NPOT textures, i.e. there is no extension as for
OpenGL, so we now add COGL_FEATURE_TEXTURE_NPOT to the feature flags in
_cogl_features_init.
Thanks to Gordon Williams for spotting this.
Don't let stringify.sh write to the $srcdir + use the BUILT_SOURCES var in
Makefile.am so as to ensure all .c. and .h files get generated from their
corresponding .glsl files before building other targets.
If the timeline is running backwards, the completed signal handler should
set the final state from the interval's initial value.

When rendering a glyph run from a texture we were premultiplying the
colour once in display_list_render() and then again in
display_list_render_texture(). This was causing the color to come out
wrong. This fixes bug #1775.
Thanks to Pierre-Luc Beaudoin for reporting.
The wrong part of an expression was bracketed in the test to determine
when a new texture matrix needed to be loaded which resulted in the
first pass through _cogl_material_layer_flush_gl_sampler_state
not uploading any user matrix.
clutter_text_move_word_backward/forward() calls did not use the
start argument consistently. Also, clutter_text_move_word_forward()
bound check checked the wrong end.

When a letter key is pressed with the control key held down one of
three things will happen :-
a) If the stage is embedded within a GtkClutterEmbed the unicode value
will be filled from gdk_keyval_to_unicode. This will be the same
value as if control was not pressed (so Ctrl+V will be 'v').
b) If the stage is not in a GtkClutterEmbed and Clutter is running on
the X11 backend then it will try to fill in the unicode value from
XLookupString. This *will* take into account the control so the
unicode value will represent a control character (Ctrl+V will be
'\x16').
c) Most other backends will not bother to fill in the unicode
value. Therefore clutter_keysym_to_unicode will be used which also
does not take into account the control key (so Ctrl+V will be 'v').
For cut and paste to work in Nbtk, the control keys need to bubble up
to the parent NbtkEntry container. This works fine for 'b' but not 'a'
and 'c'.
This patch makes ClutterText always allow the event to bubble if the
key is not handled by the binding pool and the control modifier is
down.
Ideally ClutterText would always get a unicode value that takes into
account the modifiers but this is probably best left up to the input
methods.

g-ir-compiler currently opens the library for the .gir it is compiling;
to make that work we need to set LD_LIBRARY_PATH before running
g-ir-compiler to include .libs.
(I think this may have been working earlier because there was a
hack that substituted .so with .la and tried opening that; that
works for the incorrect libclutter-glx-1.0.so but not for the
correct libclutter-glx-1.0.so.0)

Update the sed hack for the shared library to be more robust.

When dumping a ClutterUnits structure to a string we are using a bare
g_strdup_printf(), which unfortunately is locale dependant. So, for
instance, a type of CLUTTER_UNIT_EM and a value of 42 are stringified
as:
C: 42.00 em
en_GB 42.00 em
it_IT 42,00 em
fr_FR 42,00 em
This would not be a problem -- clutter_units_from_string() allows both
'.' and ',' as fractionary part delimiters. The test suite, on the
other hand, does not know that, and it checks for exact matches with
the C locale.
Calling setlocale(LC_ALL,"C") at the beginning of the conformance test
suite is not a good idea, because it would prevent external testing; and
it's a lame cop out from doing exactly what we have to do -- pick a format
and stick with it.
Like other platforms, languages and frameworks before us, we opt to
be less liberal in what we create; so, we choose to always stringify
ClutterUnits with fractionary parts using '.' as the delimiter.

Clutter advertises itself on X11 as implementing the _NET_WM_PING protocol,
which is needed to be able to detect frozen applications; this allows us to
stop the destruction of the stage by blocking the CLUTTER_DELETE event and
wait for user feedback without the Window Manager thinking that the app has
gone unresponsive.
In order to implement the _NET_WM_PING protocol properly, though, we need
to add the _NET_WM_PID property on the Stage window, since the EWMH states:
[_NET_WM_PID] MAY be used by the Window Manager to kill windows which
do not respond to the _NET_WM_PING protocol.
Meaning that an unresponsive Clutter application might not be killable by
the window manager.

The version number in the title made sense when we were breaking
API with every minor release. Now that we're API stable we can
drop that and make the output in Devhelp and on the website slightly
more good looking.
