1 Clutter 1.9.16 2012-03-19
2 ===============================================================================
4 • Clutter 1.10.0, release-candidate 1
6 • List of changes since Clutter 1.9.14
8 - Support implicit animatable properties
9 Various properties of ClutterActor can now be implicitly animated when
10 using the public setters, instead of going through the animation API;
11 this is an opt-in mechanism for the 1.x API series.
13 - Introduce paint nodes
14 ClutterPaintNode is an element of the render tree; it is used to store
15 the pipeline state and the geometry to be drawn. Actors have the ability
16 to be painted using the paint nodes by overriding the paint_node() virtual
17 function instead of the paint() virtual function. For the 1.x API series
18 the render tree will be consumed per-actor, but the plan is to build a
19 full tree as the authoritative source for the 2.x API series.
21 - Support Content delegates
22 ClutterContent is an interface that allows creating classes that will
23 painted in place of an actor's paint() virtual function. Clutter provides
24 two content types: Canvas, a Cairo-based immediate canvas for drawing the
25 contents of an actor; and Image, a content that will paint image data.
27 - ClutterText improvements
28 The caret of editable text actors is now centered, and the background
29 color will be respected when painting the actor.
31 - Support for the XInput 2.2 extension
32 Clutter will now relay touch events coming from the X server, as well
33 as precise scrolling delta, for devices with those two capabilities.
34 The support is still experimental, and limited to the X11 platform for
38 Slovenian, Assamese, Bulgarian, Spanish, Galician, Belarusian, Traditional
39 Chinese (Hong Kong and Taiwan), British English, Hebrew, Polish, Catalan,
40 Khmer, Russian, Finnish, Odia, Brazilian Portuguese, Danish, Lithuanian,
41 Portuguese, Czech, Swedish, French.

65 Clutter 1.9.14 2012-03-05
66 ===============================================================================
68 • List of changes since Clutter 1.9.12
70 - Support custom versioning boundaries for the API
71 Now that GLib provides macros for changing the minimum required and
72 maximum allowed version of a library, Clutter can respect the
73 boundaries expressed using CLUTTER_VERSION_MIN_REQUIRED and
74 CLUTTER_VERSION_MAX_ALLOWED.
76 - Add version information to deprecations
78 - Move all deprecated symbols to separate header files
80 - Documentation and annotation fixes.
82 - Accessibility fixes in Cally
83 Do not use ClutterActor:name as the accessible name, and do not
84 provide the extents of an accessible object if the actor to which
85 it refers is not on screen.
87 - Updates to the Wayland compositor and client support
88 Clutter now allows being used for creating hybrid Wayland/X11
89 compositors, working with KMS and evdev directly.

107 Clutter 1.9.12 2012-02-23
108 ===============================================================================
110 • List of changes since Clutter 1.9.10
112 - Add ClutterTimeline:repeat-count and deprecate :loop
113 The :repeat-count property supercedes the :loop property, and it
114 provides a way to specify the number of repeats that a timeline
115 should perform - with the option of specifying an "infinity" value.
117 - Add a progress mode for ClutterTimeline
118 This begins the "soft deprecation" of ClutterAlpha. Instead of
119 requiring a full object to compute an easing function out of a
120 linear progress coming from ClutterTimeline, we should have this
121 functionality on ClutterTimeline itself. Since ClutterAlpha is
122 still exposed in API that we cannot deprecate (such as virtual
123 functions) we cannot deprecate it fully, and we'll have to wait
124 until the 2.0 API bump to get rid of it.
126 - Fix ClutterBoxLayout allocation
127 Since the update of the box layout algorithm there have been a
128 bunch of regressions; now the layout works as intended.
130 - Improve the performance of the shader-based effect in Clutter
131 The effects shipped with Clutter now use the CoglSnippet API
132 internally, which allows efficient generation of the shader code;
133 they also ensure that the shader is generated once per class, and
134 shared across instances. These changes should improve performance
135 when using effects provided by Clutter.
137 - Update the internal usage of Cogl API
138 Clutter should strive to use the Cogl 2.0 API internally and not
139 mix the 1.0 and 2.0 API.
141 - Allow accessing Wayland input devices
142 This is a change that allows Clutter-based toolkits to interact
143 with Wayland in a meaningful way for operations like resize and
146 - Add a convenience CLUTTER_BIND_ALL enumeration
147 This allows binding both position and size of an actor when using
148 a ClutterBindConstraint.
151 Use the newly added API to reimplement focus tracking.
153 - Visual Studio project updates
155 - Add clutter_text_coords_to_position()
156 This method roundtrips the position_to_coords() one, and allows
157 retrieving the index of the character at the given actor-relative
160 - Documentation updates.
162 - Introspection annotation fixes.

178 ===============================================================================
180 • List of changes since Clutter 1.9.8
182 - Provide symbolic names for pointer buttons
183 The primary, middle, and secondary pointer buttons now have simple and
184 easy to remember constants that can be used in place of the "magic"
187 - Add ClutterActorIter
188 A simple API, using a stack allocated opaque structure, for safely and
189 efficiently traverse the children of a ClutterActor.
191 - Fix regression introduced by the default FixedLayout layout manager
192 Existing ClutterActor subclasses using their own layout management should
193 now work exactly like in Clutter 1.8.
195 - Documentation fixes
196 Including introspection annotations fixes.
198 - Updates to the Wayland backend
199 The Wayland client backend is now up to date with the 0.85 release of
200 the Wayland protocol.

217 ===============================================================================
219 • List of changes since Clutter 1.9.6
221 - Fix regressions in users of deprecated API
222 Also, allow to mix the new Actor API with the old Container API without
225 - Add GResource support in ClutterScript
226 GResource is a new infrastructure in GIO that allows to compile resources
227 like UI builder files and image data into a shared library or an
228 executable. A newly added method to ClutterScript makes it possible to
229 load a UI definition from a resource, like it's done for files and
232 - Update the Wayland client backend
233 The SHM transport API has changed upstream, and the Clutter backend has
234 been updated to reflect it.
238 Rob Bradford, Fran Diéguez
240 Clutter 1.9.6 2012-01-19
241 ===============================================================================
243 • List of changes since Clutter 1.9.4
245 - Deprecate clutter_actor_show_all() and clutter_actor_hide_all()
246 The latter never did make a lot of sense: hiding the parent will
247 effectively hide the children as well; the former was there only for
248 convenience, but Actors are visible by default.
250 - Gracefully handle existing code
251 The changes in ClutterActor introduced regressions in existing code
252 because of the new functionaly that was introduced to replace deprecated
253 classes like Box and Group. These regressions have hopefully been fixed;
254 Clutter 1.9.6 has been tested with a project as complex as the GNOME
257 - Fix build with binutils-gold
258 The private dependencies were not used when building Clutter, and this
259 made the Gold linker angry.
261 - Allow tracking of an actor's first and last child
262 ClutterActor has two new properties, :first-child and :last-child; these
263 are read-only properties that can be used by toolkits based on Clutter
264 to track the first and last child whenever they change.
266 - Bump the Cogl dependency
267 The 1.9.4 release depended on Cogl ≥ 1.9.4, but the minimum required
268 version was not bumped along with the changes.
270 • List of bugs fixed since Clutter 1.9.4
273 #668137 - FTBFS: pangoft2 check seems to be broken
275 Clutter 1.9.4 2012-01-17
276 ===============================================================================
278 • List of changes since Clutter 1.9.2
280 - New scene graph API in ClutterActor
281 ClutterActor now provides the API for adding, removing, and iterating
282 over the list of children; this deprecates most of the ClutterContainer
283 API. ClutterActor implements ClutterContainer as well, which means that
284 all actors can be containers.
286 - Layout management updates
287 ClutterActor now have an horizontal and vertical alignment properties
288 that will be used when added to a parent; a margin has also been added
289 to the ClutterActor class. Both margin and alignment will be automatically
290 managed during the allocation, so they will work out of the box. It is
291 also possible to set a ClutterLayoutManager delegate object on any
292 ClutterActor instance: the LayoutManager will take care of the layout
293 policy for the children of an actor.
295 - Add ClutterTextBuffer
296 The ClutterTextBuffer class provides a storage for the contents of
297 a ClutterText actor; the same instance can be shared across different
298 actors as well. The main use for ClutterTextBuffer is implementing
299 secure memory storage for the contents of a ClutterText in password
303 ClutterGroup, ClutterBox, and ClutterRectangle have been deprecated; their
304 functionality is now available directly in ClutterActor. The old child
305 actor management API in ClutterActor and ClutterContainer has been
306 deprecated as well. Other deprecations include the ClutterStage
307 fog-related properties and API; the ClutterContainer.sort_depth_order(),
308 raise(), and lower() virtual functions; the internal child push and
309 pop methods on ClutterActor.
311 - ClutterTimeline can parse markers from ClutterScript
312 Markers can now be defined inside ClutterScript, and a ClutterTimeline
313 will be able to automatically add them from a UI definition.
315 - Add a diagnostic mode
316 Similar to the GLib diagnostic mode, Clutter now supports an environment
317 variable that will print out diagnostic messages for deprecations and
318 warnings that can only be detected at run-time.
320 - Wayland backend updates
321 The wayland backend now tracks the latest API changes in the client API,
322 and Clutter now provides a Wayland surface actor that allows to write
323 Wayland compositors, similarly to the X11TexturePixmap actor for the
326 • List of bugs fixed since Clutter 1.9.2
329 #665040 - The offscreen effect always recreates the texture if
330 create_texture() is overridden to change the size
331 #665052 - The internal effects should queue a repaint on the effect not
332 on the actor when a property changes
333 #664996 - clutter_state_set_key (allow-none)
334 #664336 - path: Fix introspection annotations
335 #664252 - in case GLSL shader fails to compile clutter-shader-effect.c

349 Clutter 1.9.2 2011-11-22
350 ===============================================================================
352 • List of changes since Clutter 1.8
354 - Multi-backend build, and run-time backend selection
355 Clutter can be built with support for multiple backends in the same
356 shared library; the backend singleton is determined at run-time,
357 either with the default backend for the platform, or using the value
358 of the CLUTTER_BACKEND environment variable.
360 - GDK windowing system backend
361 A new backend has been added, which uses the GDK API for creating the
362 drawing surface, as well as receiving the windowing system and input
365 - Show a hint when ClutterText is in password mode
366 If the password-hint-time ClutterSettings property is set to a non
367 zero value, the last character entered inside a ClutterText actor when
368 in password mode will be shown in plain for the duration of the timeout,
369 before being replaced by the glyph chosen as the password character.
371 - Improve Windows build support
372 Clutter now provides project files to build the library using Visual
373 Studio 9 and Visual Studio 10. Also, the scripts to build Clutter using
374 MinGW have been improved.
376 - Remove the requirement for using clutter_threads_init()
377 Threads are initialized by default (depending on the platform), so there
378 is no need to call clutter_threads_init().
380 - Deprecate the default ClutterStage
381 The semantics of the default Stage were not obvious, and had the tendency
384 - Move the deprecated headers into their own directory
385 This should help developers identify the deprecated API.
387 - Change deprecation policy
388 Deprecated functions are now marked using compiler annotations, instead
389 of being forcibly disabled through pre-processor directives from the
390 headers. Deprecations will cause compiler warnings, and thus are enabled
391 by default. If you're building your project with compiler flags that
392 consider every warning a fatal error, you can use the symbol
393 CLUTTER_DISABLE_DEPRECATION_WARNINGS to disable the deprecation warnings.
395 - Translation updates
396 Portuguese, Assamese, Punjabi, Tamil, Oriya, Telugu, French, German,
397 Danish, Traditional Chinese (Hong Kong and Taiwan), Catalan, Esperanto,
398 Lithuanian, Galician, Norwegian bokmål, Slovenian, Hebrew, Bulgarian.

446 ===============================================================================
448 • List of changes since Clutter 1.7.14
450 - Make sure that setting :use-markup does not depend on the order
451 Setting the :use-markup property should yield the same results regardless
452 of whether the :text property is also set before or after. This applies to
453 ClutterText defined using ClutterScript as well.
455 - Protect against multiple unrealize call on ClutterStage
456 This should fix a segmentation fault in clutter-gtk when unrealize() is
457 called multiple times on an already unrealized stage.
459 - Fortify ATK event listener
460 Make sure that we subscribe only to the events we want to, and avoid
461 warnings caused by AT-SPI, as well as a leak.

489 ===============================================================================
491 • List of changes since Clutter 1.7.12
493 - Use newer version of ATK
494 Cally now depends on the latest version of ATK, to reduce the amount of
495 ad hoc code needed and to use newer features that simplify the
496 implementation of accessible objects in Clutter.
498 - Allow using Layout Managers with generic containers
499 Layout managers should not assume that they are allocating the whole
500 area available from the Actor using them; this allows actors that
501 support concepts like padding or margin to use a LayoutManager internally
505 Add a recipe on how to bind a ClutterState to the signals of objects
506 defined in ClutterScript. We also install the cookbook examples inside
507 the $datadir/clutter-1.0/cookbook/examples directory.
509 - Improve examples in the API reference
510 Some of the interactive test suite units are actually good examples of
511 how to use the Clutter API; we can use the XInclude tags to include the
512 source code inside the API reference.
514 - Ensure thread safety of the repaint functions add/removal
515 Fix a long standing issue where adding or removing repaint functions
516 was not acquiring a lock; now it's safe to manipulate the repaint
517 functions list from different threads.
519 - Make the ClutterText:line-wrap property work again
520 In 1.2 the :line-wrap property was broken, and ClutterText would paint
521 a PangoLayout wrapping until it fit the height of the allocation
522 regardless of whether the :line-wrap property was set to FALSE or
523 TRUE. Now we clip the PangoLayout before rendering it, if the :line-wrap
524 property is set to FALSE and there is no ellipsization policy set.
526 - Disable redirection to offscreen buffer by default
527 Whenever a ClutterActor with children was not fully opaque, the actor
528 was redirected to an FBO, to perform correct opacity computations.
529 Sadly, this can lead to 3x slowdowns, given the amount of framebuffer
530 objects created and the state changes that have to be performed. We
531 decided to turn off this feature by default, to avoid the performance
532 hit. It is still possible to enable this feature on a per-actor basis,
533 though, and will work to reduce the hit in future versions of Cogl,
534 Clutter and the drivers.

553 ===============================================================================
555 • List of changes since Clutter 1.7.10
557 - Reload the font caches on X11 when the user installs a new font
558 Whenever the user installs a new font inside one of the directories that
559 ware being watched by a session daemon, or changes the fontconfig
560 configuration, the toolkits using FontConfig (either directly or indirectly
561 e.g. through Pango, like Clutter) should listen to the Fontconfig/Timestamp
562 XSETTINGS key and release all the font configuration caches. This allows
563 selecting the newly installed fonts without requiring the user to restart
566 - Allow using "font-description" as a ClutterScript alias for "font-name"
567 ClutterText:font-description allows passing a PangoFontDescription
568 directly to a ClutterText; when defining a ClutterText instance inside a
569 ClutterScript file, :font-description should be an alias for :font-name,
570 which takes a string and converts it to a PangoFontDescription.
572 - Make sure that LayoutManager subclasses take the allocation origin
573 into account when allocating the children
574 A LayoutManager should be resilient against allocations with an origin
575 not positioned at (0, 0); this allows actors using a layout manager
576 instance to munge the box and implement things like margin and padding
577 without the layout manager having knowledge of those concepts.
580 Always link against libm when building Clutter (and its tests); don't
581 rely on libraries lower on the stack to do so.

619 Clutter 1.7.8 2011-08-15
620 ===============================================================================
622 • List of changes since Clutter 1.7.6
624 - Various fixes in Cally
625 Make sure to use Clutter's API and remove old workarounds that were put
626 into place when Cally was a separate project and targeting pre-1.0 API
629 - Add ClutterCairoTexture:auto-resize
630 This property makes it easier to create 2D canvas surfaces by tracking
631 the actor's allocation in a backward compatible way.
633 - Add ClutterAnimatable.interpolate_value()
634 This new virtual function deprecates the animate_property() virtual of the
635 Animatable interface, which was sub-optimal in different ways.
637 - Allow using Animatable implementations with ClutterState
638 Thanks to the new interpolate_value() virtual it is now possible to use
639 the Animatable interface with ClutterState; this allows animating
640 action, constraint and effect properties using the same "@" syntax also
641 used by ClutterAnimation and clutter_actor_animate().
643 - Improve ClutterModel's implementation
644 Avoid a bunch of needless checks, and make sure that the ::row-changed
645 signal is emitted in all cases when a row has been changed through the
646 ClutterModelIter API. The conformance test unit for ClutterModel has
647 also been improved to avoid future regressions.
649 - Improve ClutterStage behaviour on OS X
650 Make sure that the fullscreen, multi-screen and key focusing are
651 well-behaved on OS X, by implementing the correct delegate methods.
653 • List of bugs fixed since Clutter 1.7.6
657 #655387 - Missing GObject introspection annotations
658 #655306 - Added windowDidChangeScreen delegate to fix pick errors when
659 window moved to different screen
660 #655311 - Prevent hiding of unrelated application windows when stage returns
662 #655307 - Fix resource leak on subsequent calls to clutter_stage_osx_realize
663 #648633 - gnome-shell notification pop-ups do not emit

673 Clutter 1.7.6 2011-07-26
674 ===============================================================================
676 • List of changes since Clutter 1.7.4
678 - Accessibility fixes in Cally
679 Fix the implementation of the AtkText interface for ClutterText.
681 - Depend on the new Cogl windowing system API.
683 - Add functions for retrieving the clip boundaries on the Stage
684 The clutter_stage_get_redraw_clip_bounds() function is useful for
685 window managers (like Mutter) that need to retrieve the clipped
686 region used on the Stage.
688 - Auto-detect the default flavour when building
689 The default flavour used when building should be set depending
692 - Mark the OSX backend as non-experimental
693 The OSX backend is being developed, and maintained, so it should
694 not be considered experimental.
696 - Make sure that Gestures are cancelled when missing release events
698 - Correct the rounding for paint volumes
699 Try to provide stable results against potential floating point rounding
700 margins when projecting 3D paint volumes into screen bounding boxes;
701 this should avoid re-creating FBOs and always correctly handle clipped
704 - Do not clobber XI2 events data
705 This allows to play along with other toolkits using XI2.
707 - Fix ClutterSnapConstraint's right edge snapping
710 ClutterScore, clutter_texture_new_from_actor(),
711 clutter_cairo_texture_create*()

744 Clutter 1.7.4 2011-07-04
745 ===============================================================================
747 • List of changes since Clutter 1.7.2
749 - Unify the GLX and EGL backends to be a single code base
750 The GLX and EGL backends shared most of their code, and with the split
751 out Cogl, we can unify the code base into a single backend. The API as
752 well as the ABI are preserved.
754 - Restore a wider range of Z values for actors
755 The computation for the near and far planes given the perspective
756 transformation used to set up the viewport was broken in 1.7.2, and
757 the distance from the focal point was greatly reduced. This has now
760 - Bump up the dependency of Cogl
761 New windowing system API in Cogl required bumping the minimum version
762 to the latest development snapshot, 1.7.2.
764 - Add ClutterDropAction
765 The ClutterDropAction is an action for allowing ClutterActors to react
766 when an actor being dragged through ClutterDragAction crosses, or is
769 - Add a performance test suite
770 This suite is an addition to our conformance and interactive test
771 suites; the infrastructure can be used by buildbots and report tools
772 to track performance regressions across various commits.
774 - Documentation and annotation fixes
778 • List of bug fixes since Clutter 1.7.2
782 #650329 - ClutterModifierType: Port fix from GDK to clutter's GDK copy

806 Clutter 1.7.2 2011-06-13
807 ===============================================================================
809 • List of changes since Clutter 1.6.0
811 - Cogl moved out of tree
812 The Clutter OpenGL abstraction library has been moved to a separate
813 repository and can be used as a stand-alone shared library. Clutter
814 has been modified to depend on Cogl's experimental API.
816 - Correctly composite non fully opaque children
817 Non fully opauqe actors with non fully opaque children will automatically
818 redirect children paint operations to offscreen buffers, which allow
819 correct composition taking into account the overall opacity of the scene's
820 sub-graph. The same mechanism can be used to create a paint cache, and
821 paint that cache when the actor or its children do not change, instead of
822 painting the whole sub-graph again.
824 - Allow connecting signals to ClutterState states in ClutterScript
825 When defining a scene using ClutterScript it's possible to directly
826 connect a state inside a ClutterState object (both defined in
827 ClutterScript or in code) to an object's signal, without using an
828 explicit signal handler in the code.
830 - Long-press handling in ClutterClickAction
831 ClutterClickAction will detect a long-press gesture and emit signals
832 to query, activation and cancellation.
834 - Added ClutterGestureAction and ClutterSwipeAction
835 ClutterGestureAction is a generic "pointer gesture" action; it doesn't
836 provide an implementation: it's up to the developer to add the gesture
837 recognition code. ClutterSwipeAction is a GestureAction sub-class that
838 implement the "swipe" gesture. The GestureAction API is already future
839 proof for multi-device/multi-touch, even though the multi-touch isn't
840 currently implemented.
842 - Allow Effects to influence picking
843 Effects that change the geometry of a ClutterActor should also be
844 allowed to change the picking code to make sure that event handling
845 keeps working. ClutterEffect has a new pick() virtual function for

1086 API provide access to the same features.
1088 » Be more resilient against timelines controlling the state of
1089 other timelines during the clock tick.
1091 » Provide defines for the windowing platforms, to allow portable
1092 applications to include the correct header and select the
1093 correct API depending on the target.
1095 » Introduce a fast path for cogl_read_pixels() that uses the journal
1096 to determine the position of a single pixel on the stage; this
1097 fast path gracefully degrades to the usual render-based approach,
1098 and should speed up picking considerably in the case of opaque
1099 quads batched together.
1101 » Support XInput axis data on valuator devices, and introduce XInput2
1102 support for event translation and device hotplugging. The support
1103 for XI and XI2 must still be explicitly enabled by the developer,
1104 but it is now compiled in by default. It can be disabled at compile
1105 time by passing --disable-xinput to the configure script.
1107 » Clean up the unintentionally leaked internal symbols in the X11
1110 » Allow defining the contents of the rows of a ListModel using
1111 ClutterScript. This completes the ability to fully define a
1112 ClutterListModel inside a UI definition file.

1276 » Deprecate ClutterBehaviour and its sub-classes: the same functionality
1277 is available using the animation framework.
1279 » Add ClutterSnapConstraint, a constraint implementation that snaps
1280 together the edges of two actors.
1282 » Add ClutterPathConstraint::node-reached.
1284 » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
1285 not used internally any more, and since it's not integrated with
1286 the master clock it's of relative use.
1288 » Add a named, global color palette.
1290 » Add the ClutterTimeline:reverse property, for automatically
1291 reversing the direction of a timeline after the emission of
1292 the ::completed signal.
1294 » Performance improvements in the clip stack.
1296 » Do not use pointer grabs in ClutterClickAction.
1298 » Improve the internally used Cogl API for primitives, paths and
1299 buffers; this is the first step towards Cogl 2.0.
1301 » Allow using the COGL_DEBUG environment variable to disable the
1304 » Plug a nasty infinite loop in the XSETTINGS implementation.
1306 » Internally rename CoglMaterial to CoglPipeline; this should make
1307 it clearer that the API refers to the state of the GPU pipeline.
1309 » Add support for clipped redraws on EGL using the NOK_swap_region
1314 » Use the monotonic clock API if compiling against GLib ≥ 2.27.3.
1316 » Update examples in the Cookbook.
1318 » Add a Cookbook recipe for looping animations.
1320 » Add more documentation on Constraints.
1322 » Documentation fixes.
1324 Translation updates:

1331 Damien Lespiau, Lucas Rocha, Maxim Ermilov, Piotr Drąg,
1332 Tomeu Vizoso, muflone
1335 ===============================================================================
1337 • List of changes since Clutter 1.5.2
1339 » Add a backend for Wayland.
1341 » Depend on GLib ≥ 2.26, Cairo ≥ 1.10.
1343 » Do not generate the conformance tests list using the test-conformance
1346 » Implement interval progress functions for ActorBox, Vertex, Geometry,
1349 » Allow overriding the surface creation in Clutter.CairoTexture.
1351 » Add interpolate() method to Clutter.Color.
1353 » Add ClutterPathConstraint, a simple constraint that sets the origin
1354 of an actor's allocation to follow a ClutterPath.
1356 » Plug some memory leaks.
1358 » Fix build of the CEx100 and EGL backends.
1360 » Fixes for the OSX backend.

1376 Clutter 1.5.2 (04/10/2010)
1377 ===============================================================================
1379 • List of changes since Clutter 1.4.0
1381 » Add API to ClutterActor to allow any actor to define its 3D paint
1382 volume and its stage-relative 2D bounding box; the paint volume is
1383 the 3D space occupied by an actor during the paint sequence. This
1384 allows better sizing of the FBOs, and opens the door to scenegraph
1385 culling and accurate clipped redraws. The mechanism is opt-in: actors
1386 have to implement the get_paint_volume() virtual function. Callbacks
1387 attached to the ::paint signal will also disable any culling and
1388 clipped redraw in place internally.
1390 » Plug a leak in ClutterActor by disposing all constraints.
1392 » Rework the build system to be as non-recursive as possible; this should
1393 speed up the build of Clutter, and makes the build layout easier to
1394 understand and update.
1396 » Remove the internal copy of JSON-GLib; the internal copy was falling
1397 behind at a spectacular level, and it was actually making the build
1398 rather complicated - also by adding an unwanted, but needed,
1399 introspection data generation. The required JSON-GLib has also been
1400 bumped to the new stable release, 0.12.0.
1402 » Use g_object_install_properties() with GLib 2.26.
1404 » Implement ClutterContainer::child-notify, which slipped through the
1405 cracks of many development cycles without anyone noticing.
1407 » Document and test clutter_actor_contains(), especially the corner
1410 » Plug a leak in CoglTexture2DSliced.
1412 » Plug a leak in ClutterAnimator's handling of timelines.
1414 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
1415 errors when the GLX pixmap is destroyed behind Cogl's back.
1428 Clutter 1.4.0 (24/09/2010)
1429 ===============================================================================
1431 • List of changes since Clutter 1.3.14
1433 » Add support for describing ClutterState states using ClutterAnimators
1438 » Include ClutterConstraints into the allocation phase, to avoid layout
1439 cycles and improve the performance.
1441 » Add new recipes to the Cookbook to illustrate constraints-based
1444 » Fix the request mode of ClutterBoxLayout.
1446 » Fix the handling of transformations in ClutterOffscreenEffect.
1448 » Documentation and introspection fixes.

1467 of multiple children.
1469 » Add a Clutter EGL backend for Intel CEx100 platforms.
1471 » Add new recipes in the Cookbook:
1472 - texture cross-fading
1473 - ClutterScript definitions
1476 - reusing complex animations
1478 » Add methods to retrieve the clicked button and to force a release
1481 » Documentation fixes in the API reference.
1483 » Cache a full pick buffer and re-use it in case the scene does not change
1486 » Fix a Valgrind report of memory corruption in ClutterState.remove_key().
1488 » Allow detaching animations created with clutter_actor_animate().
1490 » Depend on GObject-Introspection >= 0.9.5.
1492 » Provide introspection data for the X11-specific API, like
1493 ClutterX11TexturePixmap
1495 » Use a template material for ClutterTexture to minimize the creation of
1498 » Split ClutterDragAction:drag-threshold into two, per-axis properties:
1499 :x-drag-threshold and :y-drag-threshold.
1501 » Allow disabling the -Bsymbolic flag when linking.
1503 » Use gettext >= 0.17 to handle the localization.
1505 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
1506 a crash when dealing with clip stacks.
1508 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
1509 freeing the X11 Pixmap to avoid an error.
1511 » Avoid regenerating the CoglMaterial programs too many times.
1532 Clutter 1.3.12 (16/08/2010)
1533 ===============================================================================
1535 • List of changes since Clutter 1.3.10

1545 during the ::allocate implementation
1547 » Add a ClutterTableLayout, a layout manager for tabular layouts.
1549 » Capture ENTER and LEAVE events on the stage within the DragAction.
1551 » Plug memory leaks.
1553 » Use g_object_notify_by_pspec(), if available, to speed up the
1554 emission of the ::notify signal on property changes.
1556 » Re-use the Cogl texture atlas for the CoglPango glyphs cache,
1557 and improve the performance with large font sizes.
1559 » Various fixes in the Materials comparison and inheritance.
1561 » Add the ability to associate a user program to a material.
1572 Clutter 1.3.10 (04/08/2010)
1573 ===============================================================================
1575 • List of changes since Clutter 1.3.8
1577 » Fix a locale-dependent conversion from double to string when
1578 generating ARBfp programs for the materials.
1580 » Use the XKB extension on X11 platforms to convert between hardware
1581 keys to key symbols.
1583 » Documentation fixes in the API reference.
1585 » More recipes, with videos and full examples, in the Cookbook.
1587 » Add localization support and initial translations of error messages

1626 AlignConstraint logic.
1628 » Update the internal COGL tesselator with the latest GLU code.
1630 » Fix CoglTexture data readback.
1632 » Use GL_MAX_TEXTURE_SIZE on GLES when checking the supported texture size.
1634 » Add missing public functions from COGL headers.
1636 » Fix GLES build after the Cogl material changes.
1638 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
1640 » Split the clutter_state_change() method into two:
1641 clutter_state_set_state(), for animated state changes; and
1642 clutter_state_warp_to_state() for immediate state changes.
1644 » Documentation and introspection fixes.
1658 Clutter 1.3.6 (30/06/2010)
1659 ===============================================================================
1661 • List of changes since Clutter 1.3.4
1663 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
1664 available, by using EXT_framebuffer_blit. Both mechanisms are also
1665 throttled to avoid taking all resources when using them in a compositor
1668 » Use (and cache) fragment shaders instead of texture combiners inside
1669 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
1670 to fixed functions depending on the level of support of the underlying
1673 » Implement a new design for materials; this allows scaling up the
1674 number of materials in a scene, and also makes copying materials
1677 » Make Cogl materials responsible for depth testing, and add new
1680 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
1681 object instead of using the stencil buffer, or the scanline rasterizer
1682 on platforms without a stencil buffer.
1684 » Add ClutterDeformEffect, a base class for effects that deform an
1685 actor's geometry when painting it; ClutterPageTurnEffect is an
1686 implementation of a "page curl" deformation using the DeformEffect
1689 » Always use scissoring when clipping, to reduce the amount of buffer
1690 that has to be cleared.
1692 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
1693 a constructor property; the default remains fragment shader.
1695 » Remove the button of the press event from the DragAction::drag-begin
1696 and DragAction::drag-end signals. This is an API break from 1.3.4.
1698 » Do not promote clipped redraws to full redraws.
1700 » Improve the consistency of the default state name in ClutterState,
1701 both in the API and in the serialization format.
1703 » Fix a rounding error with the Text layout size.
1705 » Add utility functions for CoglMatrix and CoglColor.
1707 » Avoid a re-allocation cycle warning when resizing the surface of
1708 a CairoTexture actor from within the allocate() implementation.
1710 » Do not add the GL libraries for the EGL X11 backend.
1712 » Add more checks for size of data passed to the shader types GValue
1715 » Add width and height to the BindConstraint.
1717 » Parse actions, constraints and effects inside an actor definition
1720 » Merge the code of native and x11 backends for EGL into a single
1721 backend; also allow creating GL context with the EGL backend.
1723 » Use XSETTINGS to set up the backend configuration options, like
1724 the font name, resolution, font options and double click options,
1725 on X11; this also allows ClutterText actors created using the
1726 default font name to be updated when the font name and options
1727 change; similarly, this allows ClutterUnits to be updated when
1728 the screen resolution changes.
1730 » Implement the texture_from_pixmap extension support inside Cogl
1731 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
1733 » Documentation improvements in the API reference and in the cookbook.
1735 » Use the -Bsymbolic-functions linker option on supported platforms
1736 to avoid intra-library PLT jumps.
1738 » Fix painting transparent stages on X11 using the :use-alpha property
1741 » Fix emission of scroll events on Windows.
1760 Clutter 1.3.4 (07/06/2010)
1761 ===============================================================================
1763 • List of changes since Clutter 1.3.2
1765 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
1766 way an actor paints itself.
1768 » Clutter provides a base class for effects painting to an
1769 offscreen buffer, and a base class for effects using the
1770 GL programmable pipeline (through the GLSL shader language).
1772 » Clutter also provides some simple, shader-based effects:
1773 ClutterBlurEffect, ClutterColorizeEffect and
1774 ClutterDesaturateEffect.
1776 » Effects can be applied to any actor, and can also be stacked.
1778 » Add ClutterClickAction, an action that provides "button-like"
1779 semantics for any ClutterActor.
1781 » ClutterDragAction now moves the actor to which it has been applied
1782 by default, using a class handler for the ::drag-motion signal.
1784 » Add the :pick-with-alpha property to ClutterTexture; this property
1785 allows using the alpha channel of a texture when picking it.
1787 » Regenerate the mipmaps on COGL textures when a texture is modified.
1789 » Documentation and build fixes.
1798 Clutter 1.3.2 (24/05/2010)
1799 ===============================================================================
1801 • List of changes since Clutter 1.2
1803 » Add ActorMeta, a class for run-time composition of actions and
1804 constraints on a ClutterActor:
1806 » Add ClutterAction, a class for implementing business logic
1807 related to event handling.
1809 » Add ClutterConstraint, a class for implementing business
1810 logic related to sizing and positioning.
1812 » ClutterDragAction is an Action sub-class that implements
1813 signals and properties for dragging actors.
1815 » ClutterAlignConstraint and ClutterBindConstraint are two
1816 Constraint sub-classes that allow relative positioning
1817 with fixed layout managers.
1819 » Add ClutterState, an object for defining state transitions.
1821 » Add ClutterBoxLayout:homogeneous property.
1823 » Implement retained clip stacks.
1825 » Support retained paths.
1827 » Add an experimental vector3 API.
1829 » Require GLib >= 2.18.
1831 » Require Atk >= 1.7.
1833 » Make ClutterActor implement AtkImplementor, and allow retrieving
1834 an AtkObject from a ClutterActor.
1836 » Improve ClutterText's Pango layout caching mechanism.
1838 » Fix set up of the GLX_SGI_swap_control extension.
1842 » Documentation fixes for Clutter and COGL.
1844 » Fix the conformance test suite by executing every test unit in
1847 » Add platform-dependent defines for Cogl.
1849 » Update the MingW cross-compilation script.
1851 » New recipe in the Cookbook.

1873 » Fix introspection annotations for ClutterBox
1875 » Compilation fixes for the EGL native backend
1877 » Fix ClutterX11TexturePixmap ::queue-damage-redraw default handler
1878 registration to avoid a run-time warning
1880 » Handle TEXTURE_RECTANGLE_ARB in the 2D sliced textures, and add
1881 a test case for that extension to avoid regressions
1883 » Improve the strictness of the JSON parser in the internal copy
1884 of JSON-GLib to which we fall back in the absence of the system
1887 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
1897 Clutter 1.2.0 (02/03/2010)
1898 ===============================================================================
1900 • List of changes since Clutter 1.1.14
1902 » Improve the Animator API for consistency, and the implementation
1903 to match the intended behaviour, as documented
1905 » Add initial (and internal) support for queueing clipped region updates
1906 and let the GLX texture-from-pixmap actor take advantage of it
1908 » Support any pixel format in cogl_read_pixels()
1910 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
1913 » Consistently use :min-width and :min-height inside the Stage to define
1914 the minimum size of the Stage window
1916 » Implement the Scriptable interface for ClutterModel sub-classes; this
1917 allows setting ClutterModel columns (both types and names) in
1918 ClutterScript definitions
1920 » Add support for unsigned integer indices in the VertexBuffer API
1922 » Documentation fixes for Clutter: the coverage is now 100%
1924 » Fixes for the EGL native backend
1926 » Require libtool >= 2.2.6
1928 » Improve tests coverage
1939 Clutter 1.1.14 (24/02/2010)
1940 ===============================================================================
1942 • List of changes since Clutter 1.1.12
1944 » Fix interaction between user resizable Stages and fullscreen on X11
1946 » Define the semantics of ENTER and LEAVE events when actors are on the
1947 border of the Stage window
1949 » Take the InputDevice of an event into consideration when throttling
1952 » Round the coordinates when clipping to a rectangle in window coordinates
1954 » Always trust the user-provided coordinates when creating a CoglTexture
1955 from a foreign GL texture
1957 » Split Clutter's debug annotations from the pick and paint mode
1958 behavioural modifiers
1960 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
1961 actor using a ClutterFixedLayout manager will automatically benefit
1964 » Fix the packing order of ClutterBox so that the convention of
1965 first-in-first-painted is maintained
1967 » Documentation fixes
1975 Clutter 1.1.12 (16/02/2010)
1976 ===============================================================================
1978 • List of changes since Clutter 1.1.10

1986 » Fix rounding errors in the preferred height of the ClutterText
1989 » Remove redundant type checks in clutter_actor_get_paint_opacity()
1991 » Add support for the GLX_INTEL_swap_event extension; when using this
1992 extension on GLX the glXSwapBuffers() call becomes non-blocking and
1993 Clutter will use an event to control the master clock.
1995 » Improve consistency between ClutterBox and ClutterGroup.
1997 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
1998 Stage X window if the window was not created by Clutter itself

2016 Clutter 1.1.10 (09/02/2010)
2017 ===============================================================================
2019 • List of changes since Clutter 1.1.8
2021 » Fixed a regression in textures that caused all the textures to be
2022 drawn as white rectangles.
2024 » Fixed compilation with the Sun C compiler.
2026 » Use SSE2 instructions to premultiply RGBA images, if available.
2028 » Improve readability of ClutterActor::raise/::lower warnings.
2035 Clutter 1.1.8 (08/02/2010)
2036 ===============================================================================
2038 • List of changes since Clutter 1.1.6
2040 » Added ClutterAnimator, a class that allows defining complex
2041 implicit animations involving multiple actors and states; this
2042 class is mostly meant to be used through the ClutterScript
2043 definition format, but it provides a convenience C API for
2044 easily building animations.
2046 » New experimental COGL API to expose "hardware" buffers such as PBOs or
2047 drm surfaces. This API can be used, for instance, to make texture
2050 » Fixed the issues with resizable stages getting a 1x1 window with
2053 » Expose input devices for every event; by default, X11 and Windows
2054 backends expose the core devices only.
2056 » Add the ClutterStage:key-focus property, for key focus tracking.
2058 » Allow setting transformable value types in ClutterAnimation when
2059 calling clutter_animation_bind() and clutter_animation_update().
2061 » Delay the creation of the default Stage until clutter_stage_get_default()
2062 is actually called; this reduces the work of clutter_init().
2064 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
2066 » Improve the extendability of CoglTexture with internal backends.
2068 » Add implicit texture atlasing; Cogl will try to put every texture
2069 inside the same texture atlas by default, to avoid state changes
2070 in the driver and (hopefully) improve performance.
2072 » Fix notification of the cursor and selection changes in ClutterText;
2073 this improves the usage of Clutter from A11Y toolkits.
2075 » Do not wait for a frame if the system clock goes backwards.
2077 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
2079 » Documentation and build fixes.
2092 Clutter 1.1.6 (18/01/2010)
2093 ===============================================================================
2095 • List of changes since Clutter 1.1.4
2097 » Some fixes for the Win32 backend (bug #1905).
2099 » Profiling support via the UProf library. Configure with
2100 --enable-profile to get a report after each Clutter application is
2103 » Improved conformance tests with coverage reports via gcov.
2105 » ClutterTexture no longer tries to read back texture data into
2106 g_malloc'd memory on unrealize (bug #1842).
2108 » The CGL_• defines from cogl-defines.h have been removed. These
2109 should not have been used by any applications, but if they were
2110 being used then please replace them either with the Cogl enums or
2111 with the appropriate GL_• enum if you are using GL directly.
2113 » Added a delete-event signal to the stage.
2115 » Fix for using cogl_rectangle with different texture coordinates
2116 for multiple layers (bug #1937).
2118 » Fix for using stencil and depth buffers in FBOs on Intel drivers
2119 in Mesa (bug #1873).
2121 » Support for subtitles in ClutterMedia.
2123 » ClutterGLX will now use an RGB visual by default. For
2124 applications (and toolkit integration libraries) that want to
2125 enable the ClutterStage:use-alpha property there is a new
2126 function: clutter_x11_set_use_argb_visual().
2128 » Fix ClutterText to allow using Pango markup and attributes in
2129 the same actor (bug #1940).
2141 Clutter 1.1.4 (03/01/2010)
2142 ===============================================================================
2144 • List of changes since Clutter 1.1.2
2146 » Update the ClutterScript parser to be more resilient, and support
2147 constructor and ChildMeta properties. The parser also respects the
2148 order of the properties in the UI definitions when applying them,
2149 and will apply the properties of an Actor after building the scene
2152 » Simplified the implementation of LayoutManager sub-classes, and added
2153 support for animating a layout manager.
2155 » Allow short-circuiting some layout operations by setting a specific
2156 flag on ClutterActor.
2158 » Improve caching of the preferred size of a ClutterActor.
2160 » Allow declaring "internal children" for a ClutterContainer
2161 implementation: the memory management of these actors will be deferred
2162 entirely to the Container.
2164 » Let the ClutterStage honour the :opacity property and the alpha component
2165 of the stage color. This requires support in the Clutter backend used.
2167 » Improve Windows and OSX backends.
2169 » Simplify the feature detection code for OpenGL; this also reduced the
2170 required OpenGL version to 1.2.
2172 » Improve the matrix stack handling code. The matrices can be debugged by
2173 using the COGL_DEBUG environment variable, assuming that Clutter was
2174 compiled with the right configure-time switch.
2176 » Improve COGL API for draw buffers, and for offscreen buffer support.
2178 » Add support for text direction to ClutterActor.
2180 » Documentation, introspection and build fixes.
2197 Clutter 1.1.2 (23/10/2009)
2198 ===============================================================================
2200 • List of changes since Clutter 1.0
2202 » Add ClutterLayoutManager, an abstract proxy class for easily
2203 writing layout management policies; also add ClutterLayoutMeta,
2204 a class for storing layout properties.
2206 » Add ClutterBox, a generic container actor that relies on a
2207 ClutterLayoutManager instance to manage the layout of its
2210 » Add the following layout managers:
2212 - ClutterFixedLayout - a layout manager implementing the
2213 policy used by ClutterGroup
2215 - ClutterBinLayout - a layout manager for packing actors
2216 as layers inside the same area, with per-actor alignment
2218 - ClutterFlowLayout - a layout manager arranging actors as
2221 - ClutterBoxLayout - a layout manager arranging actors as
2224 » Remove the requirement for the backend-specific implementation
2225 of ClutterStage to be a ClutterActor: a Stage implementation must
2226 only implement the ClutterStageWindow interface. This cleans up
2229 » COGL source tree clean up and rationalization; COGL now
2230 knows the platform, and not only the driver (GL or GLES) so
2231 we can migrate part of the low-level backend code from Clutter
2232 to COGL where it makes sense.
2234 » Remove code duplication across whole COGL.
2236 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
2237 have been fixed and confirmed working.
2239 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
2240 dumps the contents of each pick() buffer into a PNG file, for
2243 » Allow interpolating intervals of ClutterUnits for animating
2244 unit-based properties.
2246 » Increase strictness and correctness of the ClutterUnits
2249 » Add GValue transformation functions for ClutterPath to and
2252 » Fix word movement in ClutterText; implement GObject getter for
2253 :use-markup; emit notification for :position; decouple the
2254 :text property from the :use-markup property.
2256 » Do not queue redraws or relayouts on actors currently being
2259 » Support #rrggbb and #rgb notations for ClutterColor.
2261 » Multiple bug fixes.
2263 » Provide _NET_WM_PID on the X11 stage implementation.
2265 » Documentation and Introspection annotation fixes.
2267 » Add test units for the ClutterActor size requesition.
2271 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
2272 back to Shave on older Automake versions.
2292 Clutter 1.0.0 (28/07/2009)
2293 ===============================================================================
2295 • List of changes since 0.9.8
2297 » Allow per-stage disabling of motion event throttling; this should allow
2298 platforms or applications that require all the motion events not for
2299 drawing purposes to get them exactly like Clutter gets them from the
2302 » Various documentation fixes.
2304 » Add per-word key navigation inside ClutterText.
2306 » Fix the RGB<->HLS conversion.
2308 » Various fixes for the OSX backend.
2310 » Various build-related fixes.
2318 Clutter 0.9.8 (17/07/2009)
2319 ===============================================================================
2321 • List of changes since 0.9.6
2323 » Add more introspection annotations for language bindings.
2325 » Fix a bug in clutter_animation_set_alpha(), which also broke the
2326 clutter_actor_animate_with_alpha() function.
2328 » Check if the stage requires a relayout before showing it; this fixes
2329 a bug in the X11-based backends, especially under compositing window
2330 managers, where a 640x480 window would flicker before the default
2331 stage was shown for the first time.
2333 » Performance fixes for Cogl.
2335 » Sliced textures were broken by the COGL journalling.
2337 » Use the redraw cycle when asynchronously loading textures from
2340 » Miscellaneous compilation fixes for the OS X and Windows backends.
2342 » Allow querying from within the paint function of an Actor whether
2343 the actor is currently being directly painted or by a Clone actor.
2345 » In the GLX backend, when using the non-implicit sync-to-vblank inside
2346 glXSwapBuffers(), call glFinish() to avoid potential tearing.
2356 Clutter 0.9.6 (01/07/2009)
2357 ===============================================================================
2359 • List of changes since 0.9.4:
2361 » Allow the manipulation of the actor's transformation matrix, so that is
2362 is possible to apply additional transformations in a way that is
2363 compatible with the transformations already applied by the scene graph.
2365 » Fix a race in the X11 backend that happened between resizing the stage
2366 drawable and the call to glViewport().
2368 » Merge the cogl-journal-batching branch; this branch implements batching
2369 the geometry of the elements of the scene graph before sending it to
2370 OpenGL, thus minimizing the number of state changes and improving the
2371 overall performance of Clutter-based applications.
2373 » Add more debugging states for Clutter and COGL, which allow the developer
2374 to track the state of the journal; to check the VBO fallback paths; to
2375 disable picking for reliable profiling; to disable software-side matrix
2376 transformations in favour of the driver/GPU ones.
2378 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
2379 semantics; applications that drop into raw GL are, though, ignoring all
2380 the caching performed by COGL and might incur in performance issues.
2382 » Fixed the :load-async and :load-data-async properties of Texture by
2383 removing the unneeded G_PARAM_CONSTRUCT flag.
2385 » Added an initial migration guide that shows the porting process from
2386 older releases of Clutter to the 1.0 API; the first chapter deals with
2387 the migration from ClutterEffect to the new implicit animations API.
2389 » Fixed MT-safety for the master clock.
2393 Ole André Vadla Ravnås
2396 Clutter 0.9.4 (19/06/2009)
2397 ===============================================================================
2399 • List of changes since 0.9.2:
2401 » Set the layout height in ClutterText, so that wrapping and ellipsization
2402 work correctly to fill all the allocated area.
2404 » Remove all the units-based API, and migrate all the positional and
2405 dimensional accessors to use floating point values when dealing with
2406 pixels. All the properties dealing with pixels now that a floating
2407 point value as well.
2409 » Add the ability to track wether an actor is going to be painted or not,
2410 using the "mapped" flag. This also allows Clutter to be more strict
2411 in the handling of the scenegraph, ensuring correctness and avoiding
2412 wasting resources on nodes that won't be painted.
2414 » Add debugging facilities for COGL, similar to those of Clutter; through
2415 them is also possible to have an on screen debugging mode that shows the
2416 boundaries of each rectangle sent to the GPU.
2418 » Rework "units" into real logical distance units that can be converted
2419 between millimeters, typographic points and ems into pixels.
2421 » Simplify the Animation class to avoid redundancy and the possibility
2422 of it going out of sync with the Timeline and Alpha instances it uses.
2424 » Move every operation into a single "master clock" source that advances
2425 the timelines, dispatches events and redraws the stages in a predictable
2426 sequence, thus avoiding unneeded redraws. The default is to follow the
2427 sync-to-vblank cycle, if it is supported by the drivers.
2429 » Cache the glyphs geometry into a vertex buffer object to avoid
2430 resubmitting too much information to the GPU.
2432 » Rework the behaviour of ClutterModel when a filter is applied.
2434 » Allow submitting premultiplied texture data; this removes the need
2435 for unpremultiplying data in CairoTexture.
2437 » Add a simple API for submitting blending and texture combining modes
2438 through a string description.
2440 » Move Timelines to pure time-based objects.
2442 » Lots of performance improvements.
2444 » Removal of all the deprecated API.
2446 » Removal of all the fixed point entry points.
2448 » Lots of documentation fixes - the coverage is now 99% of the exported
2449 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
2451 » Generate the GObject Introspection data for both Clutter and COGL
2454 » Build environment fixes.

2731 Merge branch 'async-texture-thread-pool'
2733 Clutter 0.9.0 (30/01/2009)
2734 ===============================================================================
2736 • List of changes between 0.8.6 and 0.9.0
2738 » ClutterText is a new actor allowing text display, text editing
2739 both in multi-line and single-line modes, and text selection using
2740 the pointer devices and the keyboard. ClutterText supercedes both
2741 ClutterLabel and ClutterEntry.
2742 » ClutterClone is a new actor that allows cloning of other actors,
2743 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
2744 » ClutterBindingPool is a new API that allows to easily add key bindings
2746 » ClutterAnimation is a new API for implicit animations, similar to
2747 the tweening API used in toolkits like jQuery, Tween and Flash. This
2748 new API supercedes the ClutterEffect API.
2749 » ClutterAlpha uses "animation modes" instead of raw function
2750 pointers; it is still possible to pass alpha functions. The alpha
2751 functions provided by Clutter have been removed from the public
2752 API. It is possible to register global alpha functions and use
2753 them though a logical id.
2754 » The interval of the ClutterAlpha:alpha property has been changed
2755 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
2756 the addition of "overshooting" easing modes.
2757 » COGL now supports backface culling.
2758 » The COGL-based Pango renderer is public API and it is accessible
2759 to developers. It is also possible to access the PangoContext used
2760 by Clutter in order to create PangoLayouts to render text.
2761 » The ClutterFixed API has been moved to COGL.
2762 » COGL does not depend on Clutter data types anymore.
2763 » The ClutterMedia interface has been overhauled: implementations
2764 now must only override the interface properties. The ranges of
2765 some properties have been changed to normalized values.
2766 » COGL now exposes only floating point entry points, and reserves
2767 the eventual conversion to fixed point only when needed. The
2768 fixed point type and macros are publicly available for developers
2769 concerned about floating point operations.
2770 » COGL has a new Vertex Attribues API that allows submitting an
2771 extensible number of vertex attributes to OpenGL in a way that
2772 does not require format conversions and allows fast re-use.
2773 » COGL has a new Material API that decouples paths from fills; it
2774 is possible to create an arbitrary path and fill it with a COGL
2775 texture. The Material API also allows setting multiple texture
2776 layers and defining the blend modes and colors.
2777 » ClutterTexture has the ability to use a worker thread to asynchronously
2778 load an image from a file, as long as the GLib threading support has
2779 been enabled prior to calling clutter_init().
2780 » Clutter now supports localization of the help output, and it
2781 also supports globally setting the text direction for non left to
2783 » ClutterCairoTexture is a new actor that allows using Cairo
2784 to draw on a ClutterTexture; since Cairo does not have an OpenGL
2785 backend, the drawing is not hardware accelerated.
2786 » Clutter has a unit testing suite, based on the GLib unit test
2787 framework, which can be used to track regressions.
2788 » A ClutterPath object has been added, and it is used by the
2789 BehaviourPath. The Path object allows defining paths using a set
2790 of coordinates and operations. A Path can be "painted" either using
2791 COGL primitives or using Cairo primitives, allowing an easier way
2792 to paint non-rectangular shaped actors.
2793 » ClutterInterval is a simple object, used by ClutterAnimation, that
2794 describes an interval between two values, and interpolates between
2795 the initial and final values of the interval.

3031 ===============================================================================
3033 • List of changes between 0.7.0 and 0.7.2
3035 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
3036 to TRUE the texture will return a preferred width maintaining the
3037 aspect ratio with the given height and a preferred height maintaining
3038 the aspect ratio with the given width. This allows to set the width or
3039 the height and have the texture automatically request the height or the
3040 width respectively while maintaining the aspect ratio of the original
3043 » Added XINPUT support on the X11 backends; this provides an initial
3044 support for multiple input devices. The API is X11-specific, and
3045 provides support for querying at run-time support for XINPUT, for
3046 getting a list of input devices and for getting the type of each
3049 » The 'fruity' backend also features multiple device support.

3067 Clutter 0.7.0 (13/06/2008), "Booska"
3068 ===============================================================================
3070 • List of changes between 0.6 and 0.7.0
3072 » COGL, the underlying GL abstraction layer in Clutter, has been
3073 completely rewritten from the ground up. Its no longer a conceptual
3074 hack but a documented, fully featured library pretty much in its
3075 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
3076 OpenGL ES 2.0, providing a smart uniform API over these libraries
3077 with various utility features such as texture tiling abstractions,
3078 paths and primitive rendering, FBO, shaders, etc.
3080 » Clutter now provides an experimental backend for the Apple(tm)
3081 iPhone and iPod Touch families of products.
3083 » The Windows platform is now natively supported instead of
3084 relying on the SDL libraries. The win32 backend is still
3087 » The X11 based backends now feature support for Actors that wrap
3088 external X drawables (i.e the texture-from-pixmap extension and
3091 » Clutter now seamlessly supports multiple stages on the backends
3092 that allow this feature.
3094 » The custom Pango renderer has been completely rewritten, now using
3095 the more modern and maintained PangoCairo (instead of FT2), and avoids
3096 nasty subclassing hacks, supports smooth fast scaling of text, has
3097 many edge case issues fixed and it still is very efficient (using
3098 a texture glyph cache). It is even a little bit faster.
3100 » Better texture support, timeline improvements, ClutterLabel and
3101 ClutterEntry improvements, and container child properties are among
3102 the new features - too many to fit in the NEWS file.
3106 » #358 - "window resizing doesn't show scaled stage"

3206 which will set the anchor point at the given coordinates while
3207 adjusting the actor postion so that the relative position of the
3208 actor toward its parent remains the same.
3210 » Provide a fallback for finding the Clutter alpha functions inside
3211 a UI definition for ClutterScript in case g_module_open() fails.
3213 » Add initial Frame Buffer Objects support in ClutterTexture; using

3253 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
3254 ones, for libraries and applications depending on the X11-based

3257 » Textures are correctly unrealized before changing and freeing the
3260 » It is now possible to block the automatic call to clutter_main_quit()
3261 when closing the stage window using the frame controls by connecting
3262 an handler for the ::event signal on the Clutter stage and checking
3263 for the CLUTTER_DELETE event type and returning TRUE. This allows
3264 the usage of other main loops with GLib reactors (like Python's twisted)
3265 with Clutter without triggering assertions by closing the stage window.

3301 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
3303 Clutter 0.5.0 (02/01/2008)
3304 ==========================
3306 • List of changes between 0.4.2 and 0.5.0
3308 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
3309 flag set will receive events from the underlying backend; the event
3310 propagation chain will be walked in two directions (from the actor to
3311 the top-level container and back) with the ability to block it in
3314 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
3316 » ClutterScore, an object for controlling timelines; using a score
3317 instance is possible to start multiple timelines at once, or start
3318 a timeline after another has emitted the ::complete signal.
3320 » ClutterScript, an object for parsing a scene from an external file or
3321 a buffer; the scene is described using JSON (JavaScript Object Notation):
3322 every object is defined using its class and properties, and container
3323 objects can have their children defined as well. It is also possible
3324 do describe top-level objects such as timelines and behaviours, and to
3325 automatically connect signal handlers to signal names.
3327 » ClutterTimelines duration can now be set in milliseconds using the
3328 :duration property; the default framerate will be used to compute the
3329 actual duration in frames. The default framerate will be set by the
3330 backend, and can be overridden by the application.
3332 » ClutterTimelines direction can now be set using the :direction
3333 property; a timeline can be set to proceed forward or backward,
3334 and the direction can also be change while the timeline is still
3337 » New, experimental OSX backend.
3339 » Build environment for MS VisualStudio 2005.
3341 » ClutterModel, a generic list-based model object that can be used to
3342 implement actors following the Model-Viewer-Controller design pattern.
3343 Clutter provides a default implementation of ClutterModel, called
3344 ClutterModelDefault and using the GSequence data structure from GLib
3345 to optimize insertion and look up.
3347 » Add the ability to grab pointer and keyboard events: if an actor
3348 is set to have a grab it'll be the only one receiving events until
3349 it releases the grab.
3351 » Add the ability for an actor to receive the key focus; an actor
3352 with key focus will always receive the key events, even if it did
3353 not acquire the keyboard grab.
3355 » It is now possible to set the GL "fog" (also known as "depth cueing")
3356 effect on the ClutterStage; if the fog is enabled, actors farther
3357 away from the view point will fade into the stage background color.
3359 » Each actor now has an "anchor point", a point defined in the actor's
3360 coordinate space that will be used as the origin when scaling and
3361 rotation transformations.
3363 » Every pixel-based API has been doubled with a corresponding
3364 ClutterUnits-based function (postfixed with a '-u'), for instance:
3366 clutter_actor_set_position() - clutter_actor_set_positionu()
3367 clutter_actor_set_size() - clutter_actor_set_sizeu()
3368 clutter_actor_set_depth() - clutter_actor_set_depthu()
3370 This allows sub-pixel precision and device independence.
3372 » The ClutterLabel actor now tries very hard to provide a sane
3373 default size, if no bounding box has been requested; this fixes
3374 the :alignment property and allows the addition of the :justify
3377 » The SDL backend can now be compiled under win32 with MingW; this
3378 backend is still marked as experimental.
3380 » The OSX backend allows the compilation of Clutter under OS X; this
3381 backend is experimental.

3478 between the inner-border and the children); plus, each packed child
3479 has a padding. Margins and paddings are expressed in ClutterUnits,
3480 to ease the transition to the device independent units. You can use
3481 clutter_box_set_default_padding() if you want the same padding for

3529 Clutter 0.3 (29/06/2007)
3530 ========================
3532 • List of changes between 0.2.3 and 0.3
3533 » Clutter now supports both switchable windowing system and GL backends.
3534 Window systems supported include GLX, EGL and SDL.
3536 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
3537 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
3538 yet documented - usage external to Clutter is not yet advised.
3540 Backends may provide specific command line options.
3546 The GLX backend is built by default and is currently the most
3547 developed, supported and featured windowing system backend. Only
3548 OpenGL is supported via GLX.
3552 Clutter has experimental support for using SDL. Open GL is supported as
3553 is OpenGL ES via Dogles (very experimental).
3557 Clutter has experimental support for using EGL. Only Open GL ES
3558 is supported by EGL.
3560 EGL support assumes an EGL implementation running atop X Windows.
3565 Clutter now has experimental support for Open GL ES.
3566 Current known issues;
3568 + Unrealising a ClutterTexture will not move pixel data from video
3569 into system memory but simply destroy it.
3570 + BGRA, YUV Texture data not currently supported.
3572 (Use the clutter_feature API to probe for above at runtime)
3574 Open Source ES implementations this has been tested against
3575 include `Vincent' and `dgles'. Support for commerical
3576 implementations may require modifications to the configure.ac
3579 vincent: http://ogl-es.sourceforge.net/
3580 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
3582 dgles: http://developer.hybrid.fi/dgles/index.html
3584 » New ClutterEffect class provides a simplified (and thus less flexible)
3585 API wrapping around behaviours, alphas and timelines.
3586 » New Behaviours - bspline, ellipsis, rotation.
3587 » New built in Alpha functions;
3588 CLUTTER_ALPHA_SINE_INC
3589 CLUTTER_ALPHA_SINE_DEC
3590 CLUTTER_ALPHA_SINE_HALF
3591 CLUTTER_ALPHA_SQUARE

3598 + ClutterContainer, for generic container actors
3599 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
3600 + ClutterEntry, text entry actor
3601 » ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
3602 » All internal math now fixed point based.
3603 » Clutter now has it own internal event queue.
3604 » ClutterStage new features;
3605 + Title property for naming in window decorations.
3606 + Perspective setting - The stages perspective can now be modified.
3607 » New Clutter_actor •project API calls allow for querying of tranformed
3608 actor vertices and points.
3609 » New Clutter Feature checks.
3610 » Initial ClutterUnit implementation for device independant positioning.
3611 • List of Bugs fixed

3644 Clutter 0.2 (18-01-2007)
3645 ========================
3647 • List of changes between 0.2 and 0.1
3648 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
3649 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
3650 » Actors now have an initial floating reference; this means you
3651 don't have to explicitely unref them: every memory an actor
3652 allocates will be freed when the group containing the actor will
3654 » Add basic run-time detection of GL features.
3655 + Use GL_TEXTURE_RECTANGLE_ARB if available.
3656 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
3657 » Add API for behaviours. A ClutterBehaviour is an object which
3658 drives a set of actors using one or more properties depending
3659 on the value of an "alpha" function.
3660 + Provide simple behaviours: ClutterBehaviourOpacity,
3661 ClutterBehaviourPath and ClutterBehaviourScale.
3662 + Provide simple alpha functions for ramps and sine waveforms.
3663 » Add fixed point API for embedded platforms with no FPU.
3664 » Add support for command line switches to Clutter, like debug
3665 flags and abort on warnings; also allow application to hook up
3666 into the initialisation sequence to add their own command line
3668 » Add Pango GL renderer for Clutter, and use it to render text
3669 inside the ClutterLabel actor; this decrease texture memory
3671 » Redo Clutter Label widget, using the new Pango renderer.
3672 » Clutter Textures do not store local pixbuf copy (of texture).
3673 » Redo group and actor scale/sizing API and functionality.
3674 » Add memory management API for ClutterColor, and string parsing.
