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.
Bug 1003 - Add clutter_actor_take_key_focus()
The grab_key_focus() method is just a simple wrapper around
clutter_stage_take_key_focus() that removes the need to get
the ClutterStage of an actor in order to set the key focus.
Based on a patch by Xan López.

When the apply_transform_to_point() and its relative variant
landed in Clutter 0.3, the initial approach was to modify the
passed vertex as an in-out parameter. This was later dropped
in favour of a more consistent out parameter.
Unfortunately, the implementation never changed: both methods
where modifying the passed vertex with the partial results of
the computations.
This commit copies the contents of the "point" ClutterVertex
argument inside a stack variable and, for good measure, constifies
the argument.
Thanks to Thomas Steinacher for catching this in Python.

Bug #815 - Split up request, allocation, and paint box
* clutter/clutter-actor.[ch]: Rework the size allocation,
request and paint area. Now ::request_coords() is called
::allocate(), and ::query_coords() has been split into
::get_preferred_width() and ::get_preferred_height(). See
the documentation and the layout test on how to implement
a container and layout manager with the new API. (#915,
based on a patch by Havoc Pennington, Lucas Rocha and Johan
Bilien)

* clutter/clutter-deprecated.h: Add deprecated and replaced
API.
* clutter/clutter-entry.c: Port Entry to the new size
negotiation API.

* clutter/clutter-rectangle.c:
* clutter/clutter-texture.c: Update to use get_abs_opacity().

children to get events. Also makes groups now pickable.
(#597, #423)
* clutter/clutter-texture.c:
Handle case when 1x1 tiled texture is created,
falling 'back' to being non tiled. (#596)

Call EglTerminate on backend shutdown.
* clutter.symbols: Update exported symbols.
* clutter/clutter-actor.[ch]: Remove clutter_actor_rotate_*

* clutter/clutter-texture.c (texture_upload_data): Use
clutter_actor_get_gid(), and don't leak the filename string.
* clutter/clutter-actor.[ch]: Fix the declaration of the
class handlers for the ::captured-event, ::enter-event and
::leave-event signals; the function signatures were missing
the return value the signals marshallers were expecting, and
their names weren't respecting the convention for event-related
signals.
* clutter/clutter-actor.c: Implement part of the ClutterScriptable
interface, using the ClutterActor API to set and get the name
of an actor.
(clutter_geometry_copy), (clutter_geometry_free): Use
the slice allocator to avoid fragmentation when setting
properties and emitting signals (that is: when packing
boxed types into GValues).

Only set the fullscreen property on stage state fullscreen event(#545)
Experimental as could be painful to implement on non X backends.
* clutter/clutter-actor.[ch]: Remove the ::event-after signal
class handler, as it's not meant to be overridden by sub-classes.
(clutter_actor_class_init):
Make every event-related signal return a boolean: return TRUE
in a signal handler to block the emission. The value is accumulated
automatically by the signal API.
(clutter_actor_event): If ::event returns TRUE, skip to emitting
::event-after. Return the value accumulated by the signal emission
chain.
* clutter/clutter-private.h: Rename _clutter_boolean_accumlator().
* clutter/clutter-main.c (clutter_do_event): If clutter_actor_event()
returns TRUE then stop the event emission chain from child to parent.
* clutter/clutter-stage.c (clutter_stage_event): Behave like
clutter_actor_event().
(clutter_stage_get_key_focus),
(clutter_stage_set_key_focus): Avoid a nasty circular reference
issue: if the actor passed to set_key_focus is NULL then the stage
has the key focus.
* tests/test-events.c: Update the events test with the API
changes.

(call clutter_enable_motion_events() for per action motion events)
- clutter_stage_set_key_focus () to direct key events.
- Events bubble up to parents (ending at stage)
(original source identified by clutter_event_get_source())
TODO:
- enter/leave notifys for actors.
- stage specific events - fullscreen
- grabs
* tests/test-events.c:
Extend a little to use new API
* clutter/cogl/gl/cogl.c:
* clutter/glx/clutter-backend-glx.c:
Move get_proc_address into cogl and out of backend.
(shaders will need it)
* clutter/clutter-group.c: (clutter_group_real_lower):
Fix a minor compile warning.
* TODO:
Sync up.
* clutter/clutter-actor.[ch]: Use GInitiallyUnowned
as the parent structure in the ClutterActor structure
definition; somehow, this has escaped everyone attention
in one year and a half. Luckily, GInitiallyUnowned is
as big as GObject.
(clutter_actor_get_abs_position_units),
(clutter_actor_get_abs_position): Check parameters.
* clutter/clutter-texture.h: Unmangle the flags enum
type declaration, so that dumb parsers like h2defs.py
are not fooled.
* clutter/clutter-behaviour-ellipse.[ch]:
* clutter/clutter-effect.c: Fix some documentation
issues and make gtk-doc happy.
Most of these fixes are simple symbol shadowing issues, like index and the
braindead y0 and y1 extern symbols exported by math.h on GNU libc systems.
There is a masking issue in ClutterTexture which should be checked; I ran
the tests and everything looked fine.
The rest are just unused variables.
* clutter/clutter-actor.h:
* clutter/clutter-stage.h: Add 32 padding slots; when we
reach 1.0 it'll be a long road until the following ABI
break.
* tests/test-behave.c: Don't forget to include headers.
* clutter/clutter-box.[ch]: Base class for layout containers.
* clutter/clutter-hbox.[ch]: Horizontal box actor.
* clutter/clutter-vbox.[ch]: Vertical box actor.

implementations.
* clutter/clutter-backend.c:
* clutter/clutter-backend.h:
* clutter/glx/clutter-stage-glx.c:
* clutter/glx/clutter-backend-glx.c:
Fix up rendering pipeline removing clutter_backend_XXX_stage_paint
and adding clutter_backend_XXX_redraw instead. Duplicates less
code in backends, avoids clutter_actor_paint() getting called
before stage is set up (viewport wise) and unbreaks things like
picking.
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-main.c:
* clutter/clutter-private.h:
* clutter/clutter-stage.c: (clutter_stage_get_actor_at_pos):
Redo picking functionality a different way (via color indexing)
as to provide more flexibility, possibly speed and more likely
work with GL/ES (doesn't currently however - not sure why).
* clutter/clutter-group.c:
Add groups own 'pick' method.
* clutter/cogl/cogl.h:
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c:
Move clipping funtionality into cogl.

Dont make a copy of all applied actors but use a foreach()
* clutter/clutter-behaviour-scale.c:
Give correct limits to propertys.
Tweak gravity a little more.
Update docs.
:
* clutter/clutter-behaviour.c: (clutter_behaviour_remove):
Minor warning text change.
* clutter/clutter-feature.c: (clutter_feature_wait_for_vblank):
Minor dri ioctl tweak.
* clutter/clutter-label.c:
* clutter/clutter-label.h:
Add new label_full api call.
Rework part of the show/hide machinery. Allow groups sub-classes
and composite actors to override show_all/hide_all in order to
decide which children they wish to show/hide. This means that
if an actor overrides the default show/hide virtual methods, it'll
have to chain up to the parent class show/hide. While we're at it,
provide the fully recursive clutter_actor_show_all() and
clutter_actor_hide_all() methods.
* clutter/clutter-behaviour-path.c: Add apidoc for the ClutterKnot
functions; add pathological equality case for clutter_knot_equal().
* clutter/clutter-event.h:
* clutter/clutter-feature.h:
* clutter/clutter-behaviour.c:
* clutter/clutter-behaviour-scale.c:Fix parameters name so that
gtk-doc doesn't complain.
* clutter/clutter-actor.c:
* clutter/clutter-event.c: Add apidoc
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a clutter_actor_show_all() and a
clutter_actor_hide_all() functions; provide a mechanism for
groups and composited actors to programmatically select what to
show/hide when clutter_actor_show_all() and clutter_actor_hide_all()
are called. If you are overriding the ClutterActor::show or
the ClutterActor::hide virtual methods you should chain up with
the parent class.
* clutter/clutter-group.c: Override show_all and hide_all and
recursively show/hide every child inside the group;
clutter_group_show_all() and clutter_group_hide_all() remain as non
recursive versions of clutter_actor_show_all() and
clutter_actor_hide_all() (maybe we should rename them in order
to avoid name clashes with the bindings).
* clutter/clutter-stage.c:
* clutter/clutter-texture.c: Chain up with parent class show
and hide vfuncs.
* clutter/clutter-clone-texture.h:
* clutter/clutter-clone-texture.c: Provide API for changing the
parent texture of a clone texture actor.
* examples/behave.c:
* examples/super-oh.c:
* examples/test.c: Use clutter_actor_show_all() instead of
clutter_group_show_all().
* clutter/Makefile.am:
* clutter/clutter.h:
* clutter/clutter-version.h.in: Auto-generated versioning macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Add a ClutterActor::parent-set signal,
for notificating changes of an actor's parent; add api-doc for
the actor's properties; add the ClutterActor "name" property; clean
up a bit some functions; emit the "parent-set" signal when setting
te parent and when unparenting; better warnings when lowering
and raising an actor.
* configure.ac:
* clutter/Makefile.am: Add a --enable-debug configure option,
with three levels of debugging: no, minimum and yes; default
for development releases (odd minor version) is "yes"; update
the version m4 defines; update the libtool macros: now just
changed the clutter_interface_age when releasing will update
everything else.
* clutter/clutter-behaviour-path.h:
* clutter/clutter-behaviour-path.c: Add a "knot-reached" signal,
which is emitted when the path reaches a node in the nodes list;
flesh out the documentation a bit; sync the parameters names
so that gtk-doc doesn't complain about missing stuff.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Add the alpha value to the
ClutterBehaviour::alpha_notify vfunc, so you don't have to
get the value from the alpha inside the behaviour implementations;
add more documentation.
* clutter/clutter-alpha.c: Flesh out the description.
* clutter/clutter-actor.h: Update the header.
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-scale.c: Update docs.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
Add new API clutter_actor_move_by(), clutter_actor_get_size()
* clutter/clutter-alpha.c:
* clutter/clutter-alpha.h:
Add clutter alpha sine func
* clutter/clutter-behaviours.h:
* clutter/clutter-behaviours.c:
Add a basic scale behaviour (needs work)
* examples/behave.c: (main):
More playing with new behaviour functionality
* clutter/clutter-feature.c:
* clutter/clutter-feature.h:
* clutter/clutter-main.c:
Add new experimental sync to vblank code
Set env CLUTTER_VBLANK=none to disable.
* clutter/clutter-fixed.h:
Add basic fixed point utility defines and type.
* clutter/Makefile.am:
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-group.c:
* clutter/clutter-stage.c:
* examples/super-oh.c: (main):
Add scale API and functionality.
Rework group sizing. Now group size requests have no effect
but can be scaled.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_class_init), (clutter_actor_set_property),
(clutter_actor_get_property): Add the "clip" and "has-clip"
properties.
(clutter_actor_set_clip), (clutter_actor_remove_clip): Emit
the notification for the changed properties.
(clutter_actor_has_clip): Simple accessor to the "has-clip"
property.
Big rework of the actor management semantics: now ClutterActor
objects behave like GtkObjects - that is they have an initial
"floating" reference that gets "sunk" when they are added to
a ClutterGroup. This makes a group responsible of de-allocating
each actor inside it, so you just have to destroy the group to
get every child actor destroyed. Also, now you can do:
clutter_group_add (group, clutter_video_texture_new ());
without having to care about reference counting and explicit
unreffing.
* clutter/clutter-private.h: Add private flags setter and
getter macros.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c: Clean up; inherit from GInitiallyUnowned;
add a "visible" property; add the "destroy", "show" and "hide"
signals to ClutterActorClass.
(clutter_actor_show), (clutter_actor_hide): Refactor a bit; emit
the "show" and "hide" signals.
(clutter_actor_set_property), (clutter_actor_get_property),
(clutter_actor_class_init): Implement the "visible" property; add
signals.
(clutter_actor_finalize): Do not leak the actor's name, if it is
set.
(clutter_actor_dispose): Emit the "destroy" signal here.
(clutter_actor_init): Sink the initial floating flag if needed.
(clutter_actor_destroy): Add a function to explicitely destroy
a ClutterActor.
(clutter_actor_set_parent), (clutter_actor_get_parent),
(clutter_actor_unparent): Make set_parent require a valid parent;
add unparent; check on get_parent; ref_sink the actor when
setting its parent and unref it when unsetting it. Probably we'll
need a function that does reparenting as unparent+set_parent in
a single shot.

* clutter/clutter-group.c (clutter_group_dispose),
(clutter_group_finalize), (clutter_group_add),
