The following functions are fixed:
clutter_animation_set_actor
clutter_animation_set_timeline
clutter_animation_set_alpha
This is related to bug 1392 which discusses the problem for
behaviour_set_alpha.
Bug 1392 - behaviour_set_alpha set same alpha twice lead to warning
and destroy the input alpha
The following functions are fixed:
clutter_actor_set_shader
clutter_alpha_set_timeline
clutter_behaviour_set_alpha
clutter_clone_texture_set_parent_texture
They either now reference the new value before destroying the old
value, or just return immediately if the values are the same.
It previously attempted to set the mode on the alpha using
clutter_animation_set_mode_internal, but this was setting the mode on
priv->alpha. At that point in the code priv->alpha is always NULL.
clutter_animation_set_mode_internal now takes a parameter to specify
which alpha to modify.
As of now, a key binding installed into a BindingPool is always there
and cannot be changed.
This is problematic for sub-classes trying to override the callback
or the action for a given key binding.
This commit adds the ability to override the closure for an existing
key binding inside a binding pool -- assumed the caller knows the
key symbol and modifiers used to install the key binding in the first
place.
Otherwise the call to clutter_alpha_set_func sets the mode back to
CLUTTER_CUSTOM_MODE so clutter_alpha_get_mode won't get back the same
value that was set.

Removed trailing white space from the following files:
- clutter-clone-texture.c
- clutter-texture.c
- clutter-texture.h
- cogl/cogl-texture.h
- cogl/gl/cogl-context.c
- cogl/gl/cogl-texture.c
- cogl/gl/cogl-context.h
The direction of the text depends on the locale, and it is the
basic setting needed to enable internationalization of user
interfaces.
This commit allows setting the direction of the PangoContext instance
used by Clutter by using the CLUTTER_TEXT_DIRECTION environment
variable, or by passing the --clutter-text-direction command line
argument. Valid values are:
ltr - for left-to-right locales
rtl - for right-to-left locales
The default is LTR.
Ideally, this should be a value set by the localization teams on the
PO file, but this step requires some build system surgery to allow
the translation of the Clutter strings.
When calling clutter_backend_get_font_name(), if no default font
name has previously been set, we just set the default and return
a pointer to it - like we do for the font options.
Instead of storing the default font name and size as a pre-processor
macro, use the newly added ClutterBackend API to retrieve the current
default font from the backend.
The default backend stores some of the global defaults, like the
font options, text resolution, double click settings. It should also
store the default font name, to allow various text-based actors to
share the same settings.
When the font name changes, the ::font-changed signal is emitted,
to allow actors to pick up the change.
When the ClutterBackend notifies of changes in the resolution or
font options, update the PangoContext stored by Clutter's main
context. This allows changing the backend font-related settings at
runtime.
The PangoContext should be stored once, and inside the main
Clutter context. Each actor for which clutter_actor_get_pango_context()
has been called will hold a reference on the Pango context as well.
This makes it possible to update the text rendering for Clutter
by using only public API.
Rendering text inside an actor is pretty much impossible without
using internal API to create the various pieces like the PangoContext
and the font map.
Each actor should have the ability to create a PangoContext, which
is the only object needed to generate layouts and change the various
Pango settings.
This commit adds a clutter_actor_get_pango_context() function that
creates a PangoContext inside the ClutterActor private data and allows
the creation of PangoLayouts when needed. If the actor already
has a PangoContext, the same instance is returned.
The PangoContext is created only on demand.
The ClutterBackend instance at the moment lacks the ability to
notify runtime changes of the font options and the resolution.
For this reason, this commit adds a ::resolution-changed and a
::font-changed signals to the Backend class.
The ::resolution-changed signal is emitted when set_resolution()
is called with a different DPI; ::font-changed is emitted when the
cairo_font_options_t* changes from the default.
This follows the convention of GtkLabel/GtkEntry in GTK+ and the old
ClutterEntry.
It makes it easier to use strlen/strcmp etc on the output, since we can
assume that it is always a string.
This commit also updates the test unit for ClutterText to verify that
the clutter_text_get_text() function also returns an empty string when
a ClutterText actor has been created.
The clutter-private.h header already includes cogl-pango.h with
the correct inclusion path, because the main context stores a
pointer to the font map.
There is no need for clutter-text.c to include cogl-pango.h
again since it already includes clutter-private.h.
Instead of returning CLUTTER_X11_FILTER_CONTINUE always from
clutter_x11_handle_event() return CLUTTER_X11_FILTER_REMOVE if
the event was on a stage and translated to a ClutterEvent.

The cairo pkg-config is crafted such that #include <cairo.h> should be used.
If building with a private build of cairo installed to a custom prefix
<cairo/cairo.h> can cause an un-intended cairo header to be picked up during
compilation due to /usr/include being in the header search path.
When building out of tree the generated scripts for the unit tests
need to explicitly reference the original src dir to be able to find
test-launcher.sh, like this:
$(top_srcdir)/tests/conform/test-launcher.sh
Also test-launcher.sh now passes -m slow --verbose to gtester. Without
-m slow then the wrappers dont work for some of the timeline tests.
Our beloved math.h exports, from bits/mathcalls.h, a bare "y1" symbol.
Apparently, it's unthinkable for code including <math.h> to also declare
arguments or variable named "y0", "y1" and "yn".
Anyway, the quick fix already used elsewhere in Clutter's codebase is
to rename the colliding variables "y_0", "y_1" and "y_n" - and
obviously everything similar to them as well, using the same pattern.
The name of the parameter in the header and the one in the gtk-doc
annotation on top of a function must match.
Unfortunately, there is an index() function declared inside strings.h
which makes gcc complain for the "index" argument as soon as we
enable the extra compiler flags we use when distchecking.
Hence, we need to rename "index" to "index_" in the header and in
the source files.

It is possible to change the surface size after construction with
clutter_cairo_texture_set_surface_size so it doesn't seem right to
restrict changing the properties.
clutter_cairo_texture_resize_surface_internal is called in a handler
for the notify signal. It is called there rather than directly in the
set_property handler so that changing both properties in a single
g_object_set will only cause one resize. The constructed override is
no longer needed.
resize_surface_internal will now bail out if the size of the surface
is already the right size.
Like we did for ClutterActor in commit cdb78ec4, fix ClutterTexture
usage of CoglFixed and ClutterUnit values without conversion between
the two types.
Clutter units are, at the moment, implemented as a value in fixed point
notation using the same format as CoglFixed. This is, though, an
implementation detail. For this reason, units should not be treated as
CoglFixed values and should be converted to and from fixed point using
the provided macros.
This commit updates the usage of units and fixed point values in
ClutterActor and rationalises some of the transformation code that
heavily relied on the equivalency between them.
Some drivers (e.g. Nvidia) get upset if you try to create multiple glx pixmaps
for the same server side pixmap object, even though you might have unique
client side names, we now avoid hitting this problem by destroying the current
glx pixmap early within clutter_glx_texture_pixmap_create_glx_pixmap.
A label is now displayed under the rectangle showing the current
gravity. The text for the gravity is taken from the GEnumClass. This
makes it easier to verify that the test is working correctly.
