d21b7522f8 Fix errors in keeping track of the stage bounding rectangle
* Add new clutter_geometry_union(), because writing union intersection
  is harder than it looks. Fixes two problems with the inline code in
  clutter_stage_glx_add_redraw_clip().

  1) The ->x and ->y of were reassigned to before using them to
     compute the new width and height.
  2) since ClutterGeometry has unsigned width, x + width is unsigned,
     and comparison goes wrong if either rectangle has a negative
     x + width. (We fixed width for GdkRectangle to be signed for GTK+-2.0,
     this is a potent source of bugs.)

* Use in clutter_stage_glx_add_redraw_clip()

* Account for the case where the incoming rectangle is empty, and don't
  end up with the stage being entirely redrawn.

* Account for the case where the stage already has a degenerate
  width and don't end up with redrawing only the new rectangle and not
  the rest of the stage.

The better fix here for the second two problems is to stop using a 0
width to mean the entire stage, but this should work for now.

048fcea988 clutter-actor: Initialize with the identity matrix in get_transform
The documentation and name of the get_transformation_matrix function
implies that 'matrix' is purely an out parameter. However it wasn't
initializing the matrix before calling the 'apply_transform' virtual
so it was basically just a wrapper for the virtual. The virtual
assumes the matrix parameter is in/out and applies the actor's
transformation on top of any existing transformations. This causes
unexpected semantics that are inconsistent with the documentation.

c0d5af5de5 Adds initial clipped redraw support to Clutter
A new (internal only currently) API, _clutter_actor_queue_clipped_redraw
can be used to queue a redraw along with a clip rectangle in actor
coordinates. This clip rectangle propagates up to the stage and clutter
backend which may optionally use the information to optimize stage
redraws. The GLX backend in particular may scissor the next redraw to
the clip rectangle and use GLX_MESA_copy_sub_buffer to present the stage
subregion.

The intention is that any actors that can naturally determine the bounds
of updates should queue clipped redraws to reduce the cost of updating
small regions of the screen.

Notes:
» If GLX_MESA_copy_sub_buffer isn't available then the GLX backend
  ignores any clip rectangles.

» queuing multiple clipped redraws will result in the bounding box of
  each clip rectangle being used.

» If a clipped redraw has a height > 300 pixels then it's promoted into
  a full stage redraw, so that the GPU doesn't end up blocking too long
  waiting for the vsync to reach the optimal position to avoid tearing.

  » Note: no empirical data was used to come up with this threshold so
    we may need to tune this.

» Currently only ClutterX11TexturePixmap makes use of this new API. This
  is done via a new "queue-damage-redraw" signal that is emitted when
  the pixmap is updated. The default handler queues a clipped redraw
  with the assumption that the pixmap is being painted as a rectangle
  covering the actors transformed allocation. If you subclass
  ClutterX11TexturePixmap and change how it's painted you now also
  need to override the signal handler and queue your own redraw.

  Technically this is a semantic break, but it's assumed that no one
  is currently doing this.

This still leaves a few unsolved issues with regards to optimizing sub
stage redraws that need to be addressed in further work so this can only
be considered a stepping stone a this point:

» Because we have no reliable way to determine if the painting of any
  given actor is being modified any optimizations implemented using
  _clutter_actor_queue_redraw_with_clip must be overridable by a
  subclass, and technically must be opt-in for existing classes to avoid
  a change in semantics. E.g. consider that a user connects to the paint
  signal for ClutterTexture and paints a circle instead of a rectangle.
  In this case any original logic to queue clipped redraws would be
  incorrect.

» Currently only the implementation of an actor has enough information
  with which to queue clipped redraws. E.g. It is not possible for
  generic code in clutter-actor.c to queue a clipped redraw when hiding
  an actor because actors have no way to report a "paint box". (remember
  actors can draw outside their allocation and actors with depth may
  also be projected outside of their allocation)

  » The current plan is to add a actor_class->get_paint_cuboid()
    virtual so actors can report a bounding cube for everything they
    would draw in their current state and use that to queue clipped
    redraws against the stage by projecting the paint cube into stage
    coordinates.

» Our heuristics for promoting clipped redraws into full redraws to
  avoid blocking the GPU while we wait for the vsync need improving:

  » vsync issues aren't relevant for redirected/composited applications
    so they should use different heuristics. In this case we instead
    need to trade off the cost of blitting when using glXCopySubBuffer
    vs promoting to a full redraw and flipping instead.

79acb088e7 Remove mentions of the FSF address
Since using addresses that might change is something that finally
the FSF acknowledge as a plausible scenario (after changing address
twice), the license blurb in the source files should use the URI
for getting the license in case the library did not come with it.

Not that URIs cannot possibly change, but at least it's easier to
set up a redirection at the same place.

0d428655e2 actor: Turn push/pop_internal into Actor methods
Since the "internal" state is global, it will leak onto actors that you
didn't intend for it to, because it applies not just to the actors you
create, but also to any actors *they* create. Eg, if you have a dialog
box class, you might push/pop_internal around creating its buttons, so
that those buttons get marked as internal to the dialog box. But
ctx->internal_child will still be set during the *button*'s constructor
as well, and so, eg, the label and icon inside the button actor will
*also* be marked as internal children, even if that isn't what the
button class wanted.

The least intrusive change at this point is to make push_internal() and
pop_internal() two methods of the Actor class, and take a ClutterActor
pointer as the argument - thus moving the locality of the internal_child
counter to the Actor itself.

8fc07c51a9 actor: Use GParamSpecUint for :opacity
The :opacity property is defined using a GParamSpecUchar. This usually
leads to issues with language bindings that don't have an 'unsigned
char' type and that need to explicitly handle the conversion between
G_TYPE_UCHAR and G_TYPE_INT or G_TYPE_UINT.

The property definition already specifies an interval size of [0, 255]
on the values; more importantly, GObject already implicitly transforms
between G_TYPE_UCHAR and G_TYPE_UINT (the GValue transformation
functions are registered at type system initialization time) so
switching between a GParamSpecUchar and a GParamSpecUint should not be
an ABI break.

I have tested a simple program using the opacity property before and
after the change and I cannot see any run-time warnings related to this
issue.

0057755854 profiling: Adds initial UProf support across clutter
UProf is a small library that aims to help applications/libraries provide
domain specific reports about performance.  It currently provides high
precision timer primitives (rdtsc on x86) and simple counters, the ability
to link statistics between optional components at runtime and makes report
generation easy.

This adds initial accounting for:
- Total mainloop time
- Painting
- Picking
- Layouting
- Idle time

The timing done by uprof is of wall clock time. It's not based on stochastic
samples we simply sample a counter at the start and end.  When dealing with
the complexities of GPU drivers and with various kinds of IO this form of
profiling can be quite enlightening as it will be able to represent where
your application is blocking unlike tools such as sysprof.

To enable uprof accounting you must configure Clutter with --enable-profile
and have uprof-0.2 installed from git://git.moblin.org/uprof

If you want to see a report of statistics when Clutter applications exit you
should export CLUTTER_PROFILE_OUTPUT_REPORT=1 before running them.

Just a final word of caution; this stuff is new and the manual nature of
adding uprof instrumentation means it is prone to some errors when modifying
code.  This just means that when you question strange results don't rule out
a mistake in the instrumentation.  Obviously though we hope the benfits out
weigh e.g.  by focusing on very key stats and by having automatic reporting.

bf4818bd75 actor: Just emit a relayout cycle warning
Currently, ClutterActor detects a relayout cycle (an actor causing a
relayout to be queued from within an allocate() function) and aborts
after printing out a warning. This might be a little bit too anal
retentive, and it currently breaks GTK+ embedding inside clutter-gtk
so we should probably relax the behaviour a bit. Now we just emit the
warning but we still go ahead with the relayout.

1520ba6190 actor: Add internal child flag
ClutterActor checks, when destroying and reparenting, if the parent
actor implements the Container interface, and automatically calls the
remove() method to perform a clean removal.

Actors implementing Container, though, might have internal children;
that is, children that are not added through the Container API. It is
already possible to iterate through them using the Container API to
avoid breaking invariants - but calling clutter_actor_destroy() on
these children (even from the Container implementation, and thus outside
of Clutter's control) will either lead to leaks or to segmentation
faults.

Clutter needs a way to distinguish a clutter_actor_set_parent() done on
an internal child from one done on a "public" child; for this reason, a
push/pop pair of functions should be available to Actor implementations
to mark the section where they wish to add internal children:

  ➔ clutter_actor_push_internal ();
    ...
    clutter_actor_set_parent (child1, parent);
    clutter_actor_set_parent (child2, parent);
    ...
  ➔ clutter_actor_pop_internal ();

The set_parent() call will automatically set the newly added
INTERNAL_CHILD private flag on each child, and both
clutter_actor_destroy() and clutter_actor_unparent() will check for the
flag before deciding whether to call the Container's remove method.

c4f27b1556 actor: Add a NO_LAYOUT flag for actors
Some actor implementation might avoid imposing any layout on their
children. The Actor base class usually assumes some sort of layout
management is in place, so it will queue relayouts when, for instance,
an actor is shown or is hidden. If the parent of the actor does not
impose any layout, though, showing or hiding one of its children will
not affect the layout of the others.

An example of this kind of container is ClutterGroup.

By adding a new Actor flag, CLUTTER_ACTOR_NO_LAYOUT, and by making
the Group actor set it on itself, the Actor base class can now decide
whether or not to queue a relayout. The flag is not meant to be used
by application code, and should only be set when implementing a new
container.

c9b7efec96 Add a cache of size requests
clutter_actor_get_preferred_width/height currently caches only one size
requests, for a given height / width.

It's common for a layout manager to call get_preferred_width with 2
different heights during the same allocation cycle. Typically once in
the size request, once in the allocation. If
clutter_actor_get_preferred_width is called
alternatively with 2 different for_height, the cache is totally
inefficient, and we end up always querying the actor size even
when the actor does not need a re-allocation.

c137010524 Force a relayout when showing an actor
When an actor is hidden, the parent actor is not required to
size request or allocate it. (ClutterGroup does, but, for example,
NbtkBoxLayout doesn't.) This means that the

stale when we go to show it again - they are set for the actor
but not the parent. Explicitly setting them to FALSE avoids
clutter_actor_relayout() improperly short-circuiting.

ClutterClone bases its preferred size on the preferred size of

In order for this to work, we need to have notification when

signal to ClutterActor.

Then connect to this from ClutterClone and queue a relayout
on the clone when a relayout is queued on the source.

thus implicitly breaking the assumption that set_size() is nothing more

af5e432ba9 [actor] Allow querying whether we are painted by a Clone
It would be useful inside a custom actor's paint function to be able to
tell if this is a primary paint call, or if we are in fact painting on
behalf of a clone.

In Mutter we have an optimization not to paint occluded windows; this is
desirable for the windows per se, to conserve bandwith to the card, but
if something like an application switcher is using clones of these windows,
they will not get painted either; currently we have no way of
differentiating between the two.

37bd35f592 [actor] Allow changing the transformations matrix
Currently, the transformation matrix for an actor is constructed
from scenegraph-related accessors. An actor, though, can call COGL
API to add new transformations inside the paint() implementation,
for instance:

  static void
  my_foo_paint (ClutterActor *a)
  {
    ...
    cogl_translate (-scroll_x, -scroll_y, 0);
    ...
  }

Unfortunately these transformations will be completely ignored by
the scenegraph machinery; for instance, getting the actor-relative
coordinates from event coordinates is going to break badly because
of this.

In order to make the scenegraph aware of the potential of additional
transformations, we need a ::apply_transform() virtual function. This
vfunc will pass a CoglMatrix which can be used to apply additional
operations:

  static void
  my_foo_apply_transform (ClutterActor *a, CoglMatrix *m)
  {
    CLUTTER_ACTOR_CLASS (my_foo_parent_class)->apply_transform (a, m);
    ...
    cogl_matrix_translate (m, -scroll_x, -scroll_y, 0);
    ...
  }

The ::paint() implementation will be called with the actor already
using the newly applied transformation matrix, as expected:

  static void
  my_foo_paint (ClutterActor *a)
  {
    ...
  }

The ::apply_transform() implementations *must* chain up, so that the
various transformations of each class are preserved. The default
implementation inside ClutterActor applies all the transformations
defined by the scenegraph-related accessors.

Actors performing transformations inside the paint() function will
continue to work as previously.

e6a987d670 Fix redraw queueing in the presence of cloning
We can't short-circuit the emission of ::queue-redraw for not-visible
actors, since ClutterClone uses that signal to know when things need
to be redrawn.

Calling clutter_actor_queue_redraw() out of clutter_actor_real_map() /
clutter_actor_real_unmap() was causing the flag state to get set
incorrectly from _clutter_actor_set_enable_paint_unmapped(), because
a paint queueing a redraw was not expected.

Moving queuing the redraw to clutter_actor_hide()/show() fixes this, and
also fixes a problem where showing a child of a cloned actor wouldn't
cause the clone to be repainted.

e4ff24bcff [x11] Rework map/unmap and resizing
The mapping and unmapping of the X11 stage implementation is
a bit bong. It's asynchronous, for starters, when it really
can avoid it by tracking the state internally.

The ordering of the map/unmap sequence is also broken with
respect to the resizing.

By tracking the state internally into StageX11 we can safely
remove the MapNotify and UnmapNotify X event handling.

In theory, we should use _NET_WM_STATE a lot more, and reuse
the X11 state flags for fullscreening as well.

d6d208da7d Remove Units from the public API
With the recent change to internal floating point values, ClutterUnit
has become a redundant type, defined to be a float. All integer entry
points are being internally converted to floating point values to be
passed to the GL pipeline with the least amount of conversion.

ClutterUnit is thus exposed as just a "pixel with fractionary bits",
and not -- as users might think -- as generic, resolution and device
independent units. not that it was the case, but a definitive amount
of people was convinced it did provide this "feature", and was flummoxed
about the mere existence of this type.

So, having ClutterUnit exposed in the public API doubles the entry
points and has the following disadvantages:

  - we have to maintain twice the amount of entry points in ClutterActor
  - we still do an integer-to-float implicit conversion
  - we introduce a weird impedance between pixels and "pixels with
    fractionary bits"
  - language bindings will have to choose what to bind, and resort
    to manually overriding the API
    + *except* for language bindings based on GObject-Introspection, as
      they cannot do manual overrides, thus will replicate the entire
      set of entry points

For these reason, we should coalesces every Actor entry point for
pixels and for ClutterUnit into a single entry point taking a float,
like:

  void clutter_actor_set_x (ClutterActor *self,
                            gfloat        x);
  void clutter_actor_get_size (ClutterActor *self,
                               gfloat       *width,
                               gfloat       *height);
  gfloat clutter_actor_get_height (ClutterActor *self);

etc.

The issues I have identified are:

  - we'll have a two cases of compiler warnings:
    - printf() format of the return values from %d to %f
    - clutter_actor_get_size() taking floats instead of unsigned ints
  - we'll have a problem with varargs when passing an integer instead
    of a floating point value, except on 64bit platforms where the
    size of a float is the same as the size of an int

To be clear: the *intent* of the API should not change -- we still use
pixels everywhere -- but:

  - we remove ambiguity in the API with regard to pixels and units
  - we remove entry points we get to maintain for the whole 1.0
    version of the API
  - we make things simpler to bind for both manual language bindings
    and automatic (gobject-introspection based) ones
  - we have the simplest API possible while still exposing the
    capabilities of the underlying GL implementation

With the introduction of the map/unmap flags and the split of the

the ability of a ClutterClone to paint an hidden source actor.

The override flag, when set, will force a temporary map on a

125bded814 Enforce invariants on mapped, realized, visibility states
Bug 1138 - No trackable "mapped" state

* Add a VISIBLE flag tracking application programmer's
  expected showing-state for the actor, allowing us to
  always ensure we keep what the app wants while tracking
  internal implementation state separately.

* Make MAPPED reflect whether the actor will be painted;
  add notification on a ClutterActor::mapped property.
  Keep MAPPED state updated as the actor is shown,
  ancestors are shown, actor is reparented, etc.

* Require a stage and realized parents to realize; this means
  at realization time the correct window system and GL resources
  are known. But unparented actors can no longer be realized.

* Allow children to be unrealized even if parent is realized.
  Otherwise in effect either all actors or no actors are realized,
  i.e. it becomes a stage-global flag.

* Allow clutter_actor_realize() to "fail" if not inside a toplevel

* Rework clutter_actor_unrealize() so internally we have
  a flavor that does not mess with visibility flag

* Add _clutter_actor_rerealize() to encapsulate a somewhat
  tricky operation we were doing in a couple of places

* Do not realize/unrealize children in ClutterGroup,
  ClutterActor already does it

* Do not realize impl by hand in clutter_stage_show(),
  since showing impl already does that

* Do not unrealize in various dispose() methods, since
  ClutterActor dispose implementation already does it
  and chaining up is mandatory

* ClutterTexture uses COGL while unrealizable (before it's
  added to a stage). Previously this breakage was affecting
  ClutterActor because we had to allow realize outside
  a stage. Move the breakage to ClutterTexture, by making
  ClutterTexture just use COGL while not realized.

* Unrealize before we set parent to NULL in clutter_actor_unparent().
  This means unrealize() implementations can get to the stage.
  Because actors need the stage in order to detach from stage.

* Update clutter-actor-invariants.txt to reflect latest changes

* Remove explicit hide/unrealize from ClutterActor::dispose since
  unparent already forces those
  Instead just assert that unparent() occurred and did the right thing.

* Check whether parent implements unrealize before chaining up
  Needed because ClutterGroup no longer has to implement unrealize.

* Perform unrealize in the default handler for the signal.
  This allows non-containers that have children to work properly,
  and allows containers to override how it's done.

* Add map/unmap virtual methods and set MAPPED flag on self and
  children in there. This allows subclasses to hook map/unmap.
  These are not signals, because notify::mapped is better for
  anything it's legitimate for a non-subclass to do.

Bug 1499 - clutter_actor_notify_if_geometry_changed causes sync
           layout cycles

Whenever clutter_actor_set_{width,height,x,y,size...} is used, extra
synchronous size requests are triggered in

If the get_preferred_width() and get_preferred_height() implementations
are particularly costly (e.g. ClutterText) this will result in a performance
impact.

To avoid excessive allocation or requisition cycles we use the
cached values and flags. If we don't have an allocation, we assume
that we need to notify all the properties; if we don't have a size
requisition we notify only width and height; finally, if we do have
a valid allocation we notify only on the changed values.

deed85035f Allow rotation angle properties to be negative
Bug 1167 - clutter_effect_rotate improperly clamps negative angles

The rotation angle properties had a minimum value of 0.0 but the
rotation works fine with a negative value so the limitation is
unnecessary. This makes rotation using the ClutterAnimation API more
flexible because it was previously not possible to rotate
counter-clockwise from the 0.0 position.

6bc7f4c723 [actor] Force a relayout on set_parent()
The current code that handles the invariant that the new parent
of an actor needing a layout should also be queued for relayout
is hitting the short-circuiting we do in the queue_relayout()
method.

In order to fix this we can forcibly set the actor to need a
width/height request and an allocation; then we queue a relayout
on the parent.

3e68b23ea8 Merge branch 'scale-center'
Bug 1349 - Using the anchor point to set the scale center is messy

The branch adds an extra center point for scaling which can be used
for example to set a scale about the center without affecting the
position of the actor.

The scale center can be specified as a unit offset from the origin or
as a gravity. If specified as a gravity it will be stored as a
fraction of the actor's size so that the position will track when the
actor changes size.

The anchor point and rotation centers have been modified so they can
be set with a gravity in the same way. However, only the Z rotation
exposes a property to set using a gravity because the other two
require a Z coordinate which doesn't make sense to interpret as a
fraction of the actor's width or height.

d5e5d35316 Convert the rotation centers to be AnchorCoords
Currently only the Z axis rotation center can be set using a gravity
but the other rotations also store their center as an AnchorCoord for
consistency. Specifying the center as a gravity makes less sense for
the other axes because the actors have no size along the Z axis.

The rotation angles are now stored as gdoubles and the fixed point *x
entry points have been removed.

The Z rotation can now be set with a gravity center using the
following new function:

void clutter_actor_set_z_rotation_from_gravity (ClutterActor   *self,
                                                gdouble         angle,
                                                ClutterGravity  gravity);

e10d255b83 Add a scale center property to ClutterActor
This sets the center point from which the scaling will occur. This can
be used insetad of the anchor point to avoid moving the actor. Like
the anchor point, it can be specified as either a coordinate in units
or a gravity enum.

To set the center you can use two new variants of set_scale:

clutter_actor_set_scale_full (ClutterActor *self,
                              gdouble       scale_x,
                              gdouble       scale_y,
                              int           center_x,
                              int           center_y);

or

clutter_actor_set_scale_with_gravity (ClutterActor   *self,
                                      gdouble         scale_x,
                                      gdouble         scale_y,
                                      ClutterGravity  gravity);

The ClutterFixed variants of the set_scale functions have been removed
and the scale value is now always stored as a double.

a24b9a32e5 Store when the anchor point is set from a gravity
This makes it so when the anchor point is set using a gravity enum
then the anchor point moves when the actor changes size. A new
property is added for the anchor point gravity. If the anchor point is
set from gravity then the position in units can also be retreived with
the regular API.

A new union type is used to store the anchor point with helper
accessor functions. The hope is these can be reused for the scale and
rotation center points.

e82f656590 [Automatic fixed-to-float.sh change] Applies all scripted changes
This is the result of running a number of sed and perl scripts over the code to
do 90% of the work in converting from 16.16 fixed to single precision floating
point.

Note: A pristine cogl-fixed.c has been maintained as a standalone utility API
      so that applications may still take advantage of fixed point if they
      desire for certain optimisations where lower precision may be acceptable.

Note: no API changes were made in Clutter, only in Cogl.

Overview of changes:
- Within clutter/* all usage of the COGL_FIXED_ macros have been changed to use
the CLUTTER_FIXED_ macros.

- Within cogl/* all usage of the COGL_FIXED_ macros have been completly stripped
and expanded into code that works with single precision floats instead.

- Uses of cogl_fixed_* have been replaced with single precision math.h
alternatives.

- Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
angles and math.h replacements.

df7480090d Implements a generic ClutterActorClone that doesn't need fbos.
Many use cases for clonning an actor don't require running a shader on the
resulting clone image and so requiring FBOs in these cases is overkill and
in-efficient as it requires kicking and synchronizing a render for each clone.

This approach basically just uses the paint function of another actor to
implement the painting for the clone actor with some fiddling of the model-
view matrix to scale according to the different allocation box sizes of
each of the actors.

A simple unit test called test-actors2 was added for testing.

982a678053 Add ClutterActor::create_pango_context()
Sometimes an actor needs to set specific font rendering options on
the PangoContext without changing settings for every other text-rendering
actor.

In order to do this, we need a new public method to create a Pango
context object -- preset with all the default settings -- owned by the
developer and not shared with the rest of Clutter.

This new method is called clutter_actor_create_pango_context(); while
it does not strictly depend on a ClutterActor, it is a good idea to
have it inside the ClutterActor API to map the current get_pango_context()
method and in case we start storing screen-specific data to the Actor
itself during the 1.x API cycle.

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

the provided macros.

When the apply_transform_to_point() and its relative variant
landed in Clutter 0.3, the initial approach was to modify the

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.

	relayout when needed.

	* clutter/clutter-private.h: Add new Stage private API.

	* clutter/clutter-rectangle.c: Update the get_abs_opacity()

Bug #840 - Implement prepare-paint and finish-paint signals.

	* clutter/clutter-actor.c:
	(clutter_actor_class_init): Add the ::paint, ::realize and
	::unrealize signals to ClutterActor. It is possible to
	override the paint, realization and unrealization of an
	actor without subclassing it. The ::paint signal handlers
	have the same limitations of a ClutterActor::paint implementation
	inside a subclass.

	(clutter_actor_realize),
	(clutter_actor_unrealize),
	(clutter_actor_paint): Emit the signals instead of calling
	the functions from the class vtable.

b887bddbb1 Applied patch from bug #947
* clutter/clutter-stage.c (clutter_stage_get_default): Don't grab
	the floating reference when creating the default stage. The stage
	manager will take a reference to it so it will behave as any other
	stage.
	(clutter_stage_new): Don't take the floating reference to the new
	stage but let the stage manager keep it instead.

	* clutter/clutter-stage-manager.c
	(_clutter_stage_manager_add_stage): Take a reference to the stage
	when it is added to the list.
	(_clutter_stage_manager_remove_stage): Unref the stage when it is
	removed from the list.
	(clutter_stage_manager_dispose): Keep track of the 'next' pointer
	as a separate variable so we can cope when the stage being
	destroyed removes itself from the list as the list is being
	iterated.

	* clutter/clutter-actor.c (clutter_actor_destroy): Take a
	reference at the beginning of the function even if there is no
	parent container so that overall the reference count is not
	changed when the actor is unref'd again at the bottom of the
	function. Previously it would have a net effect of leaving the
	reference count alone unless it is a top level actor in which case
	it would unref it.

Bug #928 - Reparenting a child that itself is a container
	doesn't work

	* clutter/clutter-actor.c (clutter_actor_set_parent): Realize
	an actor when setting its parent, if the parent is realized.

	* clutter/clutter-group.c:
	(clutter_group_realize), (clutter_group_class_init): Add the
	missing implementation of the ::realize() virtual function; this
	makes sure that the children of a Group are realized if the Group
	is realized. (#928)

a5cd811a9c * clutter/clutter-actor.c (clutter_actor_move_anchor_point): The
actor position was being moved in the wrong direction. Perhaps
	this was a cut-and-paste bug from move_anchor_point_from_gravity
	because in that function ax and ay represent the old anchor
	position, but in this function they represent the new.
