ClutterActor should check whether the current instance is being
destroyed and avoid performing operations like:
• queueing redraws
• queueing relayouts
It should also warn if the actor is being parented to an actor
currently being destroyed.
When showing a warning in the state checks we perform to verify that
the invariants are maintained when showing, mapping and realizing, we
should also print out the name of the actor failing the checks. If the
actor has no name, the GType name should be used as a fallback.
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
needs_width_request/needs_height_request/needs_allocate can be
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
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.

It is possible to unset the size of an actor specified with set_width()
and set_height() by using:
clutter_actor_set_size (actor, -1, -1);
Which works by unsetting the :min-*-set and the :natural-*-set properties.
Calling set_width(-1) and set_height(-1) separately, though, doesn't work
thus implicitly breaking the assumption that set_size() is nothing more
than set_width()+set_height(). This was obviously due to the face that
pre-1.0 set_width() and set_height() took an unsigned integer as an
argument.
ClutterActor parses positional and dimensional properties with a
custom deserializer. We need to:
- handle G_TYPE_INT64, the default integer type for JSON-GLib
- use G_TYPE_FLOAT for properties, since Actor switched to it
for the pixel-based ones
This makes ClutterScript work again.
The "catch all" warning for a the mapped invariant violation is too
generic: it doesn't tell you why the invariant was broken in case
we are trying to map an unparented actor - e.g. through a Clone.
The vertex that should be used by the apply_relative_transform
is the one passed in as const, and the result should be placed
inside the non-const ClutterVertext. Currently, we are using
the latter, and thus the function is completely useless.
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.

The clutter_actor_get_allocation_coords() is not used, and since
the switch to floats in the Actor's API, it returns exactly what
the get_allocation_box() returns.
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.
The clutter_actor_pick() function just emits the ::pick signal
on the actor. Nobody should be using it, since the paint() method
is already context sensitive and will result in a ::pick emission
by itself. The clutter_actor_pick() is just confusing things.
The clutter_context_get_default() function is private, but shared
across Clutter. For this reason, it should be prefixed by '_' so
that the symbol is hidden from the shared object.
ActorBox should have methods for easily extracting the X and Y
coordinates of the origin, and the width and height separately.
These methods will make it easier for high-level language bindings
to manipulate ActorBox instances and avoid the Geometry type.
The Vertex and ActorBox boxed types are meant to be used across
the API, but are fairly difficult to bind. Their memory management
is also unclear, and has to go through the indirection of
g_boxed_copy() and g_boxed_free().
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.

If we are cloning an source actor with an unmapped parent, then when
we temporarily map the source actor:
- We need to skip the check that a mapped actor has a mapped

- We need to realize the actor's parents before mapping it,
or we'll get an assertion failure in clutter_actor_update_map_state()
because an actor with an unmapped parent is !may_be_realized.

Clutter short-circuits painting when an actor's opacity is
zero. However if the actor is being painted from a ClutterClone then
it will be painted using the clone's opacity instead so the test was
broken.
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.
Sometimes it is useful to be able to track changes in the allocation
flags, like the absolute origin, inside children of a container.
Using the notify::allocation signal is not enough, in these cases, so
we need a specific signal that gives us both the allocation box and the
allocation flags.
Instead of passing a boolean value, the ::allocate virtual function
should use a bitmask and flags. This gives us room for expansion
without breaking API/ABI, and allows to encode more information to
the allocation process instead of just changes of absolute origin.
Units as they have been implemented since Clutter 0.4 have always been
misdefined as "logical distance unit", while they were just pixels with
fractionary bits.
Units should be reworked to be opaque structures to hold a value and
its unit type, that can be then converted into pixels when Clutter needs
to paint or compute size requisitions and perform allocations.
The previous API should be completely removed to avoid collisions, and
a new type:
ClutterUnits
should be added; the ability to install GObject properties using
ClutterUnits should be maintained.
If the application code calls for destruction of an actor we need
to make sure that the actor is unrealized before running the dispose
sequence; otherwise, we might trigger an assertion failure on composite
actors.
All the underlying implementation and the public entry points have
been switched to floats; the only missing bits are the Actor properties
that deal with positioning and sizing.
This usually means a major pain when dealing with GValues and varargs
functions. While GValue will warn you when dealing with the wrong
conversions, varags will simply die an horrible (and hard to debug)
death via segfault. Nothing much to do here, except warn people in the
release notes and hope for the best.
The allocate_available_size() method is a convenience method in
the same spirit as allocate_preferred_size(). While the latter
will allocate the preferred size of an actor regardless of the
available size provided by the actor's parent -- and thus it's
suitable for simple fixed layout managers like ClutterGroup -- the
former will take into account the available size provided by the
parent and never allocate more than that; it is, thus, suitable
for simple fluid layout managers.
If we are short-circuiting the paint when the opacity is zero we still
need to clear the queued_redraw flag otherwise it won't be possible to
queue another redraw of the actor until something else has caused a
paint first.
* master:
[cogl-vertex-buffer] Ensure the clip state before rendering
[test-text-perf] Small fix-ups
Add a test for text performance
[build] Ensure that cogl-debug is disabled by default
[build] The cogl GE macro wasn't passing an int according to the format string

[actor_paint] Ensure painting is a NOP for actors with opacity = 0
Make backface culling work with vertex buffers
Since it is convenient to use geometry with an opacity of 0 for input only
purposes it's a worthwhile optimization to avoid submitting anything
for such actors while painting.
The verify_map_state() internal method is conditionally compiled
if we have CLUTTER_ENABLE_DEBUG set; for this reason, all calls to
that method should be made conditional.
When destroying a top-level actor we can actually relax the verification
of the map state, since it might be fully asynchronous and we might not
re-enter inside the mainloop in time to receive the unmap notification.
For consistency, and since those signals are key-related, the
::focus-in signal is not ::key-focus-in and the ::focus-out
signal is now ::key-focus-out.
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
The flags field of ClutterActor should have accessor methods for,
language bindings.
Also, the set_flags() and unset_flags() methods should actively
emit notifications for the changed properties.
With the introduction of the map/unmap flags and the split of the
visible state from the mapped state we require that every part of
a scene graph branch is mapped in order to be painted. This breaks
the ability of a ClutterClone to paint an hidden source actor.
In order to fix this we need to introduce an override flag, similar
in spirit to the current modelview and paint opacity overrides that
Clone is already using.
The override flag, when set, will force a temporary map on a
Clone source (and its children).
ClutterContainer provides a foreach_with_internals() vfunc for
iterating over all of a container's children, be them added using
the Container API or be them internal to the container itself.
We should be using the foreach_with_internals() function instead
of the plain foreach().

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
clutter_actor_notify_if_geometry_changed.
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.

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.
When rendering a clone before this commit the clone's opacity was
combined with the opacity of the source but this is not usually the
desired effect. Instead the clone's opacity (combined with its
parents) should completely override the opacity of the source.
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()

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.

The documentation has been updated to reflect the fact that the anchor
point will move when the actor changes size if it was specified using
a gravity value. The new functions for setting the scale center and z
rotation gravity are also documented.
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);
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.
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.
Since we allow overriding the paint() implementation through the
::paint signal to change the way an actor is being painted, we
should also allow overriding the pick() implementation using a
::pick signal.
Since a pick is really a paint operation, we can safely get
the allocation box, instead of using get_width() and get_height().
This should help cutting down the function calls. If we were
feeling adventurous, we could even use the allocation directly
from the private data structure.
Based on a patch by Gwenole Beauchesne <gbeauchesne@splitted-desktop.org>
If an actor is not set as visible, or if it is in a section of
the scenegraph that it's set as not visible (e.g. one of the
parents is not visible) then we should not queue a redraw for
it.
Patch based on code from Michael Boccara <michael@graphtech.co.il>
The stage-with/height-percentage converters had been broken by
the multiple-stages support of Clutter 0.8. They are also made
useless by the fact that Units are now floating point values.
The millimeters and typographic points converters also depended
on the default stage, but they can be reworked to use the default
DPI coming from the default Backend instead.
To deal with all the corner cases that couldn't be scripted a number of patches
were written for the remaining 10% of the effort.
Note: again no API changes were made in Clutter, only in Cogl.
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.
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.
ClutterUnits should not be used interchangeably as, or with
ClutterFixed values. ClutterUnits should also not be assumed
to be integers.
This commit fixes the last few improper usages of ClutterUnit
values, and adds a CLUTTER_UNITS_FORMAT macro for safely printing
ClutterUnit values with printf().

Sometimes an actor needs to set specific font rendering options on

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.

The PangoContext should be stored once, and inside the main

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

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.

Fix merge conflict in clutter/clutter-path.h
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.
When calling clutter_actor_paint() we should be setting the
CLUTTER_ACTOR_IN_PAINT private flag. This allows signalling
to each Actor subclass that we are effectively in the middle
of a paint sequence. Actor subclasses can check for this
private flag and act based on its presence - for instance to
avoid recursion, or to detect performance degradation cases.
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 1124 - Clutter causes an additional size request in each
allocation
* clutter/clutter-actor.c:
(clutter_actor_store_old_geometry): Store the allocation instead
of causing a new size-request cycle. (Johan Bilien)
* clutter/clutter-actor.c
(clutter_actor_set_anchor_point_from_gravity)
(clutter_actor_move_anchor_point_from_gravity): Add documentation
to make it clear that the anchor point won't move when the actor
is resized.
* clutter/clutter-actor.c (clutter_actor_set_property): When
changing the anchor point properties, use set_anchor_pointu
instead of changing the value directly so that a redraw will be
queued.
(clutter_actor_set_anchor_pointu): Queue a redraw when the anchor
point is changed. Thanks to Johan Bilien.
* clutter/cogl/gl/cogl.c:

* clutter/clutter-actor.c:
(clutter_actor_queue_relayout): Remove some pointer dereferencing.
* clutter/clutter-label.c:
(clutter_label_allocate): Revert the change of r2883 and remove the
layout width cache and force a recreation of the layout every time
we receive an allocation.
This is now do-what-I-mean like clutter_actor_get_size so that if
the allocation box is available it will use that, otherwise it
will use the preferred size. clutter_actor_transform_vertices has
been converted to clutter_actor_transform_and_project_box so that
it can be used by both functions. Based on a patch by Emmanuele
Bassi.
(clutter_actor_get_abs_allocation_vertices)
(clutter_actor_get_allocation_vertices): These two functions now
force a relayout if the allocation box is not available.
* tests/test-fbo.c: Fixed the shader to use texture2D instead of
texture2DRect now that GL_EXT_texture_rectangle is no longer used.

(clutter_actor_set_min_width),
(clutter_actor_set_min_height),
(clutter_actor_set_natural_width),
(clutter_actor_set_natural_height): Ignore any override of the
minimum and natural size of the stage on backends that only
support static stages.
* clutter/clutter-stage.c (clutter_stage_allocate): Use the
preferred size of the ClutterStage implementation instead of
the display size.

a backend that provides only static stages, then override
the value and use the size of the display as returned by
the backend.

* clutter/clutter-actor.c:
(clutter_actor_set_parent): Do not emit ::parent-set when
reparenting.
(clutter_actor_unparent): Ditto, as above.
(clutter_actor_reparent): Emit ::parent-set with the old
parent and set the IN_REPARENT flag unconditionally.
* clutter/clutter-actor.c:
(clutter_actor_set_parent): Document and maintain the invariant
that after setting a realized parent on an actor, the actor is
also going to be realized.
(clutter_actor_unparent): Change the invariant that an unparented
actor is also unrealized: the paint is fast enough to avoid
unrealizing, since it also causes more problems that what it's
worth.
* tests/test-invariants.c (test_show_on_set_parent): Update the
invariants test because we changed the invariants.
* clutter/clutter-actor.c (clutter_actor_unparent): Reset the

Bug #953 - Actors are not hidden before unrealized or
disposed (Tommi Komulainen)
* clutter/clutter-actor.c:
(clutter_actor_unrealize): Hide a visible actor when unrealizing
it.
(clutter_actor_dispose): Make sure to unrealize an actor when
disposing it.
* clutter/clutter-actor.c:
(clutter_actor_dispose), (clutter_actor_destroy),
(clutter_actor_unparent): Clean up the actor's destruction
sequence, making sure that every operation is performed
under the CLUTTER_ACTOR_IN_DESTRUCTION internal flag.
Bug #964 - "unrealized" signal of ClutterActor wrongly named
* clutter/clutter-actor.c (clutter_actor_class_init): Fix typo
in the ::unrealize signal name. (Armin Burgmeier)
* clutter/clutter-actor.c: Add more clarifications on the
size and position accessors and the distinction between
transformed and untransformed actor box inside the actor's
description.
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:
(clutter_stage_get_preferred_width),
(clutter_stage_get_preferred_height),
(clutter_stage_allocate),
(clutter_stage_class_init): Port Stage to the new size
negotiation API.
* clutter/clutter-texture.c: Port Texture to the new size
negotiation API.
* clutter/clutter-types.h: Add ClutterRequestMode enumeration.
* clutter/x11/clutter-stage-x11.c: Port the X11 stage
implementation to the new size negotiation API.
* tests/Makefile.am: Add the layout manager test case.
* tests/test-opacity.c: Update.
* tests/test-project.c: Update.

using the new size negotiation API; the layout manager handles
both transformed and untransformed children.
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.
* 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)
* clutter/clutter-actor.c:
* clutter/clutter-main.c:
* clutter/clutter-private.h:
Rejid Øyvind's previous commit a little moving more into

* clutter/clutter-actor.c:
(init_bits): initialize constants about how many bits are
available/will be used for r,g,b components.
(_clutter_pix_to_id): now own function, compute an id from a
pixel into its own function (used from _clutter_do_pick).
(_clutter_id_to_col): now own function, computes the color to use for
a given id.
(clutter_actor_paint): use clutter_id_to_col.
* clutter/clutter-main.c:
(_clutter_do_pick): use _clutter_pix_to_id
(clutter_main): re-enable invocation of fruity app shell.
Bug #900 - clutter_actor_lower() and friends do not queue redraw
* clutter/clutter-actor.c:
(clutter_actor_raise),
(clutter_actor_lower): Queue a redraw after raising and lowering
and actor in the paint order stack. (#900)
actor position was being moved in the wrong direction. Perhaps

effect.
Bug 892 - Incorrect results using rotation-[center|angle] properties

contained data structure.
* clutter/clutter-id-pool.[ch]: new files.
* clutter/Makefile.am: added clutter-id-pool.[ch]
* clutter/clutter-private.h: use a ClutterIDPool instead of GArray and
GSList to keep track of the reusable ids.
* clutter/clutter-actor.c: moved id pool logic away.
* clutter/clutter-main.c: simplified id pool creation/finalization.
Add support for the anchor point inside ClutterScript (#834,
David Stanczak)
* clutter/clutter-actor.c:
(clutter_actor_set_property),
(clutter_actor_get_property),
(clutter_actor_class_init): Add the :anchor-x and :anchor-y
properties to the ClutterActor class.
(clutter_actor_set_anchor_point),
(clutter_actor_set_anchor_pointu),
(clutter_actor_set_anchor_point_from_gravity): Reimplement
the pixel based and gravity based API using the units based
one. Emit the ::notify signal for the :anchor-x and :anchor-y
properties.
(parse_units),
(clutter_actor_parse_custom_node): Parse the :anchor-x and
:anchor-y properties using the custom units format (mm, px,
pt and %).

of overflowing the id numbers when continusly creating and destroying
actors on long running applications for 16bpp.
* clutter/clutter-private.h: replaced hashtable with GArray and a
GSList for available slots in the array.
* clutter/clutter-actor.c: (create_actor_id): function to create an
actor->id mapping, (release_actor_id): function to mark an existing id
as available for reuse.

function for cleaning up the context,
(clutter_get_actor_by_gid): use the GArray for looking up actors.
* clutter/clutter-actor.c: Remove the usage of g_return_if_fail()
from static functions: either assert or use g_warning() to check
internal state, as g_return_if_fail() can be compiled out.
* clutter/clutter-main.c: Ditto as above.
* 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-rectangle.c:
* clutter/clutter-texture.c: Update to use get_abs_opacity().

disable the shader on top of the clutter context's shader stack while
rendering into the FBO.

(clutter_actor_get_property): Use clutter_actor_get_reactive()
instead of the IS_REACTIVE() macro.
(clutter_actor_set_reactive): Emit the notify signal for the
reactive property.
* clutter/clutter-timeline.c:
(timeline_timeout_func),
(clutter_timeline_get_delta): Coding style fixes.

Made to work for parentless actors.
* clutter/clutter-actor.c (clutter_actor_init): Explicitly

components converting from units to fixed point values, using
the new cogl_clip_set() signature
(clutter_actor_get_property), (clutter_actor_set_clip),
(clutter_actor_get_clip): Update the accessors of the clip
property
* clutter/clutter-actor.c:
(clutter_actor_should_pick_paint),
(clutter_actor_apply_transform_to_point): Fix the whitespace.
(clutter_actor_set_rotation): Clarify that the coordinates of
the centre of rotation are relative to the anchor point or,
if not set, to the upper left corner of the bounding box.
* clutter/clutter-actor.c: Clarify the set_clip() method
documentation, pointing out that the clip area origin is
always the top-left corner of an actor.
* clutter/clutter-actor.c: (clutter_actor_paint),
(clutter_actor_apply_shader): queue a redraw of actor when shader is
set.
* clutter/clutter-actor.h: indentation.
* clutter/clutter-shader.[ch]: made the fragment and vertex shader

(clutter_scriptable_iface_init): Add a new "rotation" custom
property for expressing the rotation along each axis in a
compact way:
"rotation" : [
{ "x-axis" : [ <angle>, [ <y>, <z> ] ] },
{ "y-axis" : [ <angle>, [ <x>, <z> ] ] },
{ "z-axis" : [ <angle>, [ <x>, <y> ] ] }
]
(clutter_geometry_get_type),(clutter_vertex_get_type),

Moved offset translation after rotation so that rotation coords
are also relative to the offset point.
* clutter/clutter-actor.c: Document the values for full
transparency and full opacity in the set_opacity()
method. (#662)

Added new function for translating stage coordinates into local
actor coordinates.
* clutter/clutter-actor.c (parse_units),
(clutter_actor_parse_custom_node): Do not allow using percentages
of the stage on the stage itself, as it makes little to no
sense.
* clutter/clutter-script.c:
(clutter_script_construct_object): Rearrange code.
* tests/test-script.json: Do not set the size of the stage, to
test for the stage size percentage.

(clutter_actor_parse_custom_node),
(clutter_scriptable_iface_init): Override the parsing code
for the x, y, width and height properties of ClutterActor,
to allow strings with modifiers when defining the position

(clutter_actor_set_anchor_pointu):
(clutter_actor_get_anchor_point):
(clutter_actor_get_anchor_pointu):
(clutter_actor_set_anchor_point_from_gravity):
New anchor point API deprecating old gravity scaling, added
comments on modelview matrix construction to ClutterActor
documentation.
(clutter_actor_set_scale_with_gravity):
(clutter_actor_set_scale_with_gravityx):
Deprecated; use clutter_actor_set_anchor_point_from_gravity() instead.
* clutter/clutter-actor.c (clutter_actor_destroy): Remove the
reference we hold on the actor, as it was preventing the finalization
of every child on the stage.
* clutter/clutter-actor.c:
(clutter_actor_real_show),
(clutter_actor_real_hide): Do not set the MAPPED flag on the actor
if it is a top-level one (like ClutterStage); the backends are
responsible for setting that flag, as it might be the result of an
asynchronous operation (e.g. on X11).
* clutter/eglnative/clutter-stage-egl.c:
(clutter_stage_egl_show),
(clutter_stage_egl_hide): Set/unset the CLUTTER_ACTOR_MAPPED flag
on show and hide respectively.
* clutter/osx/clutter-stage-osx.c:
(clutter_stage_osx_show),
(clutter_stage_osx_hide): Ditto as above.
* clutter/sdl/clutter-stage-sdl.c:
(clutter_stage_sdl_show),
(clutter_stage_sdl_hide): Ditto as above, plus chain up to the
parent class show/hide virtual functions.
* clutter/x11/clutter-event-x11.c (event_translate): Use the MapNotify
and UnmapNotify events to call the X11 stage map/unmap functions.
* clutter/x11/clutter-stage-x11.[ch]:
(clutter_stage_x11_set_fullscreen): Set the fullscreen_on_map flag
with the fullscreen value.
(clutter_stage_x11_map), (clutter_stage_x11_unmap): Set the MAPPED
flag on the stage actor and redraw; also, if the fullscreen_on_map
flag was set, call clutter_stage_fullscreen() as well. (#648)
* tests/Makefile.am:
* tests/test-fullscreen.c: Add a fullscreen test case for checking
whether fullscreen works on every backend/platform.
* clutter/clutter-actor.c:
(clutter_actor_real_request_coords),
(clutter_actor_request_coords),
(clutter_actor_class_init): Provide a default ::request_coords()
implementation in ClutterActor and use it to store the bounding
box passed to clutter_actor_request_coords(). This makes the code
more reliable and clean, and avoids a call to the subclass
request_coords() method if the bounding box did not change. Now,
every class overriding ClutterActor::request_coords() *must* chain
up to the parent class method or the bounding box will not be
saved inside the ClutterActor structure.
* clutter/clutter-entry.c:
* clutter/clutter-group.c:
* clutter/clutter-hbox.c:
* clutter/clutter-label.c:
* clutter/clutter-texture.c:
* clutter/clutter-vbox.c: Chain up to the parent class
request_coords() method.
* clutter/clutter-actor.c (clutter_actor_destroy): Bail out
if clutter_actor_destroy() was called on the stage: the stage
is not for the user to destroy.
* clutter/x11/clutter-backend-x11.c:
* clutter/eglnative/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c:
* clutter/osx/clutter-backend-osx.c: Unset the top-level private
flag on the stage when disposing it, so the backends can safely
call clutter_actor_destroy().
* clutter/clutter-private.h: Tweak the private flags accessors,
to avoid the typecheck.
* clutter/clutter-actor.c::
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-clone-texture.c:
* clutter/clutter-effect.c:
* clutter/clutter-label.c: Remove the usage of G_PARAM_CONSTRUCT
without an override for the ::construct virtual function; using
G_PARAM_CONSTRUCT to set the default value of a property is not
the recommended approach; default values are set inside the
instance init function.
(clutter_actor_set_rotation): swapped axis and angle around,
the new argument order is: (axis, angle, x, y, z). Also removed
deprecated rotation functions from header.
Updated use of clutter_actor_set_rotation? in the following files:
* clutter/clutter-behaviour-rotate.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-behaviour-bspline.c:
* clutter/clutter-behaviour-rotate.c:
* clutter/clutter-effect.c: Update internal usage of the
rotation API.

fixes for bugs #614 and #628.
* clutter/clutter-main.c:
* clutter/clutter-stage.c: Update internal usage of the actor
API.
* tests/test-events.c: Update test suite.

to ::set_id and ::get_id, to avoid potential confusion with the
ClutterActor:name property.
* clutter/clutter-script.h:
* clutter/clutter-script.c (clutter_script_construct_object): Use
clutter_scriptable_set_id().
(clutter_get_script_id): Add a public function to retrieve the ID
used in the UI definition files from an object.
* clutter/clutter-actor.c: Do not set the name of the actor with
the ID set in the UI definition files.
* tests/test-script.c: Test clutter_get_script_id().
* clutter.symbols: Update with the new symbols.
* 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).
(clutter_actor_box_copy), (clutter_actor_box_free),
(clutter_vertex_copy), (clutter_vertex_free): Ditto.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:

ClutterContainer, and call the container API only if needed.
(clutter_actor_destroy): Remove from the parent if needed,
just like the documentation says.
* clutter/clutter-actor.c:
More events documentation.
* clutter/clutter-event.c:
* clutter/clutter-event.h:
Add synthetic flag and make put_event use it
(via modded patch from pippin)
* clutter/clutter-main.c: (clutter_do_event):
dont use put event anymore when pushing enter/leave events.
* clutter/clutter-actor.c: Remove the ::event-after signal:
three event layers to connect to seems a bit overkill.
(clutter_actor_event): Return FALSE, not TRUE by default,
as g_signal_emit() will change the return value if no
handlers are connected
* clutter/clutter-stage.c: Emit ::notify when we change
the fullscreen property.
* clutter/clutter-script.c: Add more documentation for the
definition format and keywords.
(translate_property): Collapse the G_TYPE_ENUM and G_TYPE_FLAGS
cases into one, to simplify the code.
* tests/test-script.c: Test enumeration conversion by using
a value different from the default.
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-private.h:
* clutter/clutter-main.c:
Add a hash to global clutter context mapping all parented actor
id's to actors.
Add clutter_get_actor_by_id() call.
Convert picking machinery to use above.
(performance/simpler composite actor creation)
* clutter/clutter-stage.c: (clutter_stage_fullscreen),
(clutter_stage_unfullscreen), (clutter_stage_event):
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.c (clutter_actor_get_size): Implement
get_size() as a wrapper around clutter_actor_query_coords()
instead of calling g_object_get() twice.
(clutter_actor_init): Initialise the box in one call.
* 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.
* clutter/clutter-actor.c:
(clutter_actor_set_scale_with_gravityx):
Use CLUTTER_QMUL for better precission (#532, patch by Gwenole
Beauchesne).

Added missing CLUTTER_INT_TO_FIXED conversion (#544, patch by Neil
Roberts).
