* clutter/Makefile.am:
* clutter/clutter-enum-types.h.in:
* clutter/clutter-enum-types.c.in: Use template files for
glib-mkenums; this makes the Makefile template a bit more
clean and the enum types generation more customisable (e.g.
when GLib 2.14 has been released, we can use g_once_init_enter()
and g_once_init_leave() to have thread-safe GType functions
for the enum types as well).
Emit the ClutterTimeline::new-frame signal only if we arrive there with an
active timeout source. Also, make sure to take a reference on the timeout
when emitting signals.
If the timeline is advancing of zero frames, bump it up to one frame. (bug
471, Rob Bradford)
If the user called clutter_timeline_pause() while in the ::new-frame handler
the timeout is removed and the timeline is reset, while the correct behaviour
should be to simply return. (#371, Johan Bilien)
If we skipped the last frames and we ended up over the frame number, emit
the ::new-frame signal with the last frame before emitting the ::completed
signal.
Remove the call to clutter_timeline_stop() when reaching the end of the
timeline: it was used just to remove the timeout source and it emitted the
::paused signal, which doesn't make any sense. Also rewind the timeline
after emitting the ::completed signal, so that calling get_current_frame()
in the ::completed signal handlers still work.
The ownership of the ClutterAlpha object is transferred to the ClutterBehaviour
used by the effect; we just need to unref the behaviour to make the alpha
object disappear.
The clutter_timeout_pool_insert_sorted() function caused an inversion of
the timeout sources in the pool; this led to a wrong behaviour in the
execution of the timeout functions. See bug 471.
This patch drops clutter_timeout_pool_insert_sorted() in favour of the
standard g_list_insert_sorted(), which produces identical behaviours with
and without the pool.
A new test, written by Rob Bradford, has been added to the regression test
suite in order to identify sorting issues with the timeout pools.
Apply a patch from Neil Roberts (bug 468) that makes the get_center() method
of ClutterBehaviourRotate return the correct tuple of coordinates.
Also, fix some coding style issues and make sure to freeze and thaw the
GObject notification queue when emitting the notify signal on multiple
properties in one method.
Some of the API landed in trunk has been backported to the stable branch
after testing. This patch updates the Since: tag in the API reference to
reflect the time when the API was first added to a release.
When computing the increasing smoothstep alpha value use the right type
for the results, to avoid overflowing the [0, 0xffff] range of the alpha
value.
Also use the right format when printing out the opacity and alpha values
in the opacity behaviour.
Language bindings will have problems with raise() and lower() bein in both
ClutterContainer and ClutterActor; hence, this patch renames
clutter_container_raise() and clutter_container_lower() to
clutter_container_raise_child() and clutter_container_lower_child(),
respectively.

Every direct reference to ClutterGroup has been removed, in favour of
ClutterContainer - which is the official way of creating container
actors as of 0.4.
Since ClutterActor directly calls ClutterGroup methods we need ClutterContainer
to provide them, so that every container actor behaves the same way.
This patch makes ::raise, ::lower and ::sort_depth_order virtual functions
of the ClutterContainer interface, implemented by ClutterGroup.
The documentation has been added and deprecation warnings have been added
as well.
ClutterStage now uses the newly added clutter_container_find_child_by_id()
function to find the right child in the scenegraph, using the picking id.
This fixes the test-boxes test case.
Finding a child by its ID is a method that should be used by every container
and not only by ClutterGroup. This is needed to actually fix the picking in
ClutterStage.
* clutter/clutter-timeout-pool.c: Fix removing and adding timeouts
to the timeout pool during a dispatch of a timeout source already
inside the pool. (#456, based on a patch by Neil Roberts)
(clutter_timeout_dispatch), (clutter_timeout_pool_dispatch): Hold
the main Clutter lock in the pool dispatch function, instead of
the per-timeout dispatch; this guarantees that the ref+unref of
the single timeouts are done under the main lock.
Ported from 0.4 branch.
* clutter/clutter-texture.c:
Fix typo in clutter_texture_get_pixbuf (#458, #442?, Neil Roberts).
Use take_object when getting pixbuf prop to avoid ref leak
The threads_enter() and threads_leave() functions are no-ops because Clutter
is not thread-aware nor thread-safe. Leaving them in is a source of confusion
so we just remove them.
Update the NEWS and the README files with the release notes.
To avoid using a ClutterPadding each time you add an actor to a ClutterBox
when you want the same padding around each child, you can now set the
default padding. The API is pixel-based, since it's a commodity function,
and will affect only clutter_box_pack_defaults().
ClutterBox is meant to work like the HTML boxing model: it has a margin and
a backgrdound color, and every child actor is added with a pack type and a
padding. The ClutterBoxChild structure holds the child actor, the padding,
the packing type and the allocated coordinates for the actor.
* clutter/clutter-behaviour-depth.c:
Modify to work like all other behvaiours in not forcing
increasing order in behaviour 'limits'. (#436)
Rename limit min/max props to start/end.
* tests/test-depth.c:
Simplify test-case to work with above change and
without multiple ramps
* clutter/clutter-behaviour-rotate.c:
Handle CW rotation when end > start and similar for CCW just
like ellipse behaviour.
* clutter/clutter-behaviour-depth.c: Clarify that what drives
the movement along the Z axis is the ClutterAlpha object (we
don't have the luxury of a rollover like the opacity does);
so, if you want to go from 0 to -100 you have to use a
decreasing function, just as well if you want to go from 100
to 0. Using a min-depth of 100 and a max-depth of 0 and an
increasing function is undefined behaviour.

here too.

* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglx/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c: Set the default resolution
as 96.0 dpi for every backend (we already were under this
assumption anyway, and this makes it easier to change this
setting per-backend).
* clutter/pango/pangoclutter-fontmap.c:
* clutter/pango/pangoclutter.h: Allow setting the resolution
for the PangoClutterFontMap object and provide the implementation
for the PangoFcFontMap::get_resolution() virtual function. This
allows to set the resolution of the PangoContext when retrieving
it.
* clutter/clutter-label.c (clutter_label_init): Set the
resolution of the font map with the one the backend gives us.
* clutter/clutter-entry.c (clutter_entry_init): Ditto.
* clutter/clutter-stage.[ch]: Fix clutter_stage_set_user_resizable()
name, and add a getter for the property.
* clutter/glx/clutter-stage-glx.c: Use the accessor, not
g_object_get() to retrieve the value of the resizable property.
* clutter/clutter-backend.[ch]: Add clutter_backend_set_resolution()
and clutter_backend_get_resolution(); backends should use the former
to set the resolution of the display when initialising, while actors
should use the latter when sizing themselves depending on the
resolution or the font size.
* clutter/glx/clutter-backend-glx.c: Set the resolution as 96 dpi
as a default and query the X server when opening the display.
* clutter/clutter-entry.c: Drop the hardcoded dpi value and use
clutter_backend_get_resolution() to compute the default size.
* clutter/clutter-types.h: Document ClutterGravity enumeration
and remove the only incomplete symbol of the api reference. Now
we are up to 79% documented symbols.
* clutter/clutter-media.c: Document ClutterMedia signals;
replace the implementation of clutter_media_set_filename() with
something a wee bit more robust (and portable) than a sprintf().
* clutter/clutter-actor.[ch]: Use GInitiallyUnowned
as the parent structure in the ClutterActor structure

(clutter_entry_ensure_cursor_position),
(clutter_entry_new_with_text), (clutter_entry_new),
(clutter_entry_insert_unichar), (clutter_entry_delete_chars):
Fixed utf8 support so it actually works now, for both inserting and deleting
chars.
Fixed positioning of cursor for utf8 chars. Both GString and Pnago need
bytes (not documented!) for string manipulation, so making sure all values
were bytes and not char positions fixed the issue.
Set a default size of 50x50 for the entry, otherwise no chars can be seen
if the size is not set after creation (which confuses the developer).
Most of these fixes are simple symbol shadowing issues, like index and the
braindead y0 and y1 extern symbols exported by math.h on GNU libc systems.
There is a masking issue in ClutterTexture which should be checked; I ran
the tests and everything looked fine.
The rest are just unused variables.
* clutter/clutter-behaviour.h:
* clutter/clutter-behaviour.c: Rename clutter_behaviour_clear()

init function, where they belong.
* clutter/clutter-behaviour-rotate.c:
* clutter/clutter-behaviour-rotate.h:

Two small fixes for correctly debugging the deinitialisation
phase of the backend:
* clutter/glx/clutter-backend-glx.c: Remove the event source
after we unref the main stage.
* clutter/glx/clutter-stage-glx.c: Add a mark at the end of the
unrealize call (the perl bindings seem to crash before we reach
this point).
* clutter/clutter-behaviour-ellipse.c: Remove pointer indirections;
add sanity checks on the public entry points; make all the public
properties floating point (where needed) andconvert them to fixed
point internally. (Partial fix for #389)
* clutter/clutter-behaviour.[ch]: Rename ClutterBehaviour::apply
and ClutterBehaviour::remove to ClutterBehaviour::applied and
ClutterBehaviour::removed respectively, and emit them when the
behaviour has been applied (or does no longer apply) to an actor.
(clutter_behaviour_dispose), (clutter_behaviour_finalize),
(clutter_behaviour_class_init): Move the actor removal to the
::dispose virtual function, and remove the ::finalize one;
document the missing properties and signals.
(clutter_behaviour_clear): Add function to clear a behaviour:
every actor will be unreffed and the ClutterBehaviour::removed
signal will be emitted.
* clutter/clutter-event.c:
Correct clutter_event_get_state () return type. Fixes#398
* clutter/glx/clutter-stage-glx.c:
Disable use XFixes cursor visibility funcs. Appears to have issues
on feisty X Server at least. Fallback should work generally better.
Fix non offscreen clutter_stage_snapshot to also rotate read pixel
data to correct orientation.
To follow the other simple behaviours, the ClutterBehaviourDepth:min-depth
and ClutterBehaviourDepth:max-depth properties have been renamed to
ClutterBehaviourDepth:depth-start and ClutterBehaviourDepth:depth-end
respectively.
* TODO:
Updates.
* clutter/clutter-stage.c:
* clutter/glx/clutter-stage-glx.c:
Fix cursor visibility property.
Force a repaint before mapping to attempt to avoid flicker.
Always make sure that the opacity is a positive integer, even if the
start and end opacities are inverted.
Also, use the correct integer-to-pointer casts, as the opacity is an
unsigned integer.

in the ::finalize method; rename clutter_entry_add() to
clutter_entry_insert_unichar(), and clutter_entry_remove() to
clutter_entry_delete_chars() - for bindings and for matching the
insert_text() and delete_text() existing methods; add a getter
method for the max-length property.
Make ClutterEffectTemplate use a pointer to the private data to avoid
a type check each time it dereferences the ClutterEffectTemplatePrivate

All the ClutterTimeline share a ClutterTimeoutPool by default. This might
cause problems if an application is using a heavily threaded library that
does not play nicely with the main loop (like libneon). If this is the
case, using the CLUTTER_TIMELINE environment variable set to "no-pool"
makes the ClutterTimeline objects discard the pool and allocate a slice
of the main loop.

* clutter/clutter-timeout-pool.c: Make ClutterTimeoutPool
more thread-safe, using a static lock.
(clutter_timeout_pool_dispatch), (clutter_timeout_pool_remove): Fix
a race condition-turned-in-memory corruption bug, triggered by
removing a timeout from the pool while still spinning the pool
source.
Use a per-class timeout pool into ClutterTimeline so that every timeline
instance will use a pooled timeout function to execute the tick. This
should make multiple timelines not starve the main loop.
A ClutterTimeoutPool is a source for the GLib main loop which pools
multiple timeout functions. The pool is always sorted so that the first
timeout to expire is also the first element of the pool; hence, extraction
is a constant time operation. This also makes the usage of multiple
timeouts at the same priority not compete for a timeslice of the main
loop, leading to starvation.
