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-clone-texture.c: Port CloneTexture to
the new size negotiation API; it just means forwarding
the requests to the parent texture.
* clutter/clutter-deprecated.h: Add deprecated and replaced
API.
* clutter/clutter-entry.c: Port Entry to the new size
negotiation API.
* clutter/clutter-group.c: Port Group to the new size
negotiation API; the semantics of the Group actor do not
change.
* clutter/clutter-label.c: Port Label to the new size
negotiation API, and vastly simplify the code.
* clutter/clutter-main.[ch]: Add API for executing a
relayout when needed.
* clutter/clutter-private.h: Add new Stage private API.
* clutter/clutter-rectangle.c: Update the get_abs_opacity()
call to get_paint_opacity().
* clutter/clutter-stage.c:

negotiation API.

negotiation API.

implementation to the new size negotiation API.

* tests/test-opacity.c: Update.
* tests/test-project.c: Update.
* tests/test-layout.c: Test case for a layout manager implemented
using the new size negotiation API; the layout manager handles
both transformed and untransformed children.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_get_abs_opacity): Add function that does what
get_opacity() does now...
(clutter_actor_get_opacity): ... and make get_opacity() do what
it's supposed to be doing. The original get_opacity() returned
a composited value, and there's no way to actually extract the
real opacity value set with set_opacity().
* clutter/clutter-clone-texture.c:
* clutter/clutter-rectangle.c:
* clutter/clutter-texture.c: Update to use get_abs_opacity().
* clutter/clutter-entry.c:
* clutter/clutter-label.c: Ditto. Also, never change the stored
alpha value. (#804)

get_abs_opacity() API, and correct opacity handling.

* doc/reference/clutter-docs.sgml: Fix a lot of documentation.

children to get events. Also makes groups now pickable.
(#597, #423)

Handle case when 1x1 tiled texture is created,
falling 'back' to being non tiled. (#596)
* clutter/eglx/clutter-backend-egl.c:
Call EglTerminate on backend shutdown.
* clutter.symbols: Update exported symbols.
* clutter/clutter-actor.[ch]: Remove clutter_actor_rotate_*
and clutter_actor_get_rx* and provide a simpler rotation API:

* 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

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_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.

* clutter/clutter-actor.h:

Initial implementation of actors emmitting event signals (423);
- Actors set_reactive() to receive mouse events.
(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.

Fix a minor compile warning.

Sync up.
