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 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/cogl/gles/cogl.c:
* clutter/cogl/cogl.h.in: Add cogl_clip_stack_save,
cogl_clip_stack_restore, cogl_viewport and cogl_frustum.
* clutter/cogl/gl/cogl-fbo.h:
* clutter/cogl/gl/cogl-fbo.c: Try to attach a stencil buffer when
creating an FBO.
* clutter/cogl/common/cogl-clip-stack.c: Add functions to save and
restore the whole state of the stack.
* clutter/clutter-texture.c (clutter_texture_paint): When
rendering the FBO source, setup a temporary asymmetric perspective
projection matrix to render it as it would appear on screen.
* clutter/clutter-private.h:
* clutter/clutter-actor.c
(_clutter_actor_apply_modelview_transform_recursive): No longer
static and exported in clutter-private.h
(clutter_actor_get_abs_allocation_vertices): The initialization of
the local stage pointer got moved away in revision 3081 so it was
crashing if the function is called before the layout is run.
Bug 1010 - ClutterLabel does not update the layout (Lee Jusung)
* 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/clutter-actor.c:
(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.
* clutter/clutter-backend.[ch]: Remove get_display_size() and
clutter_backend_get_display_size().
* clutter/eglnative/clutter-backend-egl.c:
* clutter/fruity/clutter-backend-fruity.c:

implementations.
* clutter/clutter-actor.c:
(clutter_actor_set_min_width),
(clutter_actor_set_min_height),
(clutter_actor_set_natural_width),
(clutter_actor_set_natural_height): Add a comment explaining
the override in place for backends providing a fixed size
on a stage.
* clutter/clutter-actor.c:
(clutter_actor_set_min_width),
(clutter_actor_set_min_height),
(clutter_actor_set_natural_width),
(clutter_actor_set_natural_height): If setting the minimum
and natural width and height on a top-level actor, and on
a backend that provides only static stages, then override
the value and use the size of the display as returned by
the backend.
* clutter/eglnative/clutter-stage-egl.c:
(clutter_stage_egl_realize): Remove the setting of the
minimum and natural width and height.
actor clip being enabled or disabled in an actor paint
method. Otherwise the clip stack can be become unbalanced. This
was happening in ClutterEntry until it was fixed in revision 2983.
* clutter/clutter-actor.h:
* clutter/clutter-actor.c:
(clutter_actor_allocate_preferred_size): Add more documentation
and notes on where it's appropriate to call this function.
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
Clean up of parenting code (see #972)
Doc updates to section intro.
Add clutter_actor_allocate_preferred_size () utility call
* clutter/clutter-group.c: (clutter_fixed_layout_allocate):
Use clutter_actor_allocate_preferred_size ()
* doc/clutter-actor-invariants.txt:
Add some more notes
* 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
:show-on-set-parent property to TRUE when unparenting.
* tests/Makefile.am: Add test-invariant to the build.
* tests/test-invariants.c: Test the invariants that we are going
to honour (and document, at some point).
* clutter/clutter-actor.c:
(clutter_actor_move_anchor_point):
(clutter_actor_move_anchor_pointu):
(clutter_actor_move_anchor_point_from_gravity):
Fixed incorrect sign of position adjustment.
Fixed replace call to _move_by with move_byu in
_move_anchor_pointu.
Stripped trailing whitespace.
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.
* 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.
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-main.c and using ClutterContext.
Also Refactor clutter_init & clutter_init_with_args to share
same core init code.
framebuffer are only approximately the correct value.
* 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.
