Clutter 1.10.4 2012-05-01 =============================================================================== • List of changes since Clutter 1.10.2 - Fixes for XInput 2 event handling We should only select events for enabled devices, and keep track of the device state. - Fix an overflow when calculating the distance of very long paths - Ensure that we don't change actor visibility when restacking • List of bugs fixed since Clutter 1.10.2 [bugzilla.gnome.org] #674510 - Changing a hidden child's position with new API shows the actor #673644 - Scroll not working in document overview #652521 - get_length fails in Clutter.Path when length is greater than 46340 Many thanks to: Cosimo Cecchi, Christian Kirbach, Jasper St. Pierre, Jonh Wendell, Yuri Myasoedov. Clutter 1.10.2 2012-04-16 =============================================================================== • List of changes since Clutter 1.10.0 - Fix expansion of actors inside a TableLayout For actors that span more than one column, the wrong flag was being used to compute the expansion. - Fix text length passed to ClutterTextBuffer This should fix crashers happening when changing the contents of a TextBuffer with non-ASCII characters. - Clean up handling of in-flight changes during implicit transitions The transitions are updated using the new value, as well as the current easing state. The documentation has been updated to define the behaviour of the implicit animations. • List of bugs fixed since Clutter 1.10.0 [bugzilla.gnome.org] #673783 - ClutterTextBuffer crashes #672945 - Fixes for the implicit actor animation API #672853 - Assistant layout is broken #672890 - CRASH: ClutterAnimation finalized without disconnecting timeline #674105 - cally.pc is buggy Many thanks to: Jasper St. Pierre, Neil Roberts, Owen W. Taylor, Peter Hutterer, Stefano Facchini, Tristan Van Berkom. Clutter 1.10.0 2012-03-22 =============================================================================== • Clutter 1.10.0, new stable release • List of changes since Clutter 1.9.16 - Fix ClutterTimeline:current-repeat accessor The :current-repeat value was being incremented prior to emitting the completed signal, which meant that signal handlers would not be able to retrieve the correct value. - Improve the memory management of Transitions ClutterActor now takes a reference on the Transitions that have been added to it, and releases the reference when the Transition is removed; this means that it's safe to release the reference of a transition after adding it, to let ClutterActor own it. - Remove the Animatable argument for PropertyTransition constructor The animatable was not meant to be there in the first place; the PropertyTransition will perform validation on the property lazily, once it's been attached to the actor. - Clean up documentation and examples Ensure that the API reference is using the correct API and best practices. - Fix TableLayout policy for actors spanning multiple rows or columns The ClutterTableLayout inherited some small bug from MxTable that got fixed in the meantime; the layout policy has been re-synchronized. - Build fixes for the Wayland backend. - Updated VisualStudio project files. • List of bugs fixed since Clutter 1.9.16 [bugzilla.gnome.org] #672557 - Fix ClutterTableLayout Many thanks to: Jasper St. Pierre, Chun-wei Fan, Robert Bragg, Chao-Hsiung Liao, Neil Roberts, Rico Tzschichholz, Rob Bradford Clutter 1.9.16 2012-03-19 =============================================================================== • Clutter 1.10.0, release-candidate 1 • List of changes since Clutter 1.9.14 - Support implicit animatable properties Various properties of ClutterActor can now be implicitly animated when using the public setters, instead of going through the animation API; this is an opt-in mechanism for the 1.x API series. - Introduce paint nodes ClutterPaintNode is an element of the render tree; it is used to store the pipeline state and the geometry to be drawn. Actors have the ability to be painted using the paint nodes by overriding the paint_node() virtual function instead of the paint() virtual function. For the 1.x API series the render tree will be consumed per-actor, but the plan is to build a full tree as the authoritative source for the 2.x API series. - Support Content delegates ClutterContent is an interface that allows creating classes that will painted in place of an actor's paint() virtual function. Clutter provides two content types: Canvas, a Cairo-based immediate canvas for drawing the contents of an actor; and Image, a content that will paint image data. - ClutterText improvements The caret of editable text actors is now centered, and the background color will be respected when painting the actor. - Support for the XInput 2.2 extension Clutter will now relay touch events coming from the X server, as well as precise scrolling delta, for devices with those two capabilities. The support is still experimental, and limited to the X11 platform for the time being. - Translation updates Slovenian, Assamese, Bulgarian, Spanish, Galician, Belarusian, Traditional Chinese (Hong Kong and Taiwan), British English, Hebrew, Polish, Catalan, Khmer, Russian, Finnish, Odia, Brazilian Portuguese, Danish, Lithuanian, Portuguese, Czech, Swedish, French. • List of bugs fixes since Clutter 1.9.14 [bugzilla.gnome.org] #655491 - Text cursor/caret theming #668801 - [NSApp finishLaunching]; missing in OSX backend #656156 - Add lightness, brightness, and contrast effects #671736 - Provide translations for "default:LTR" for RTL locales #671779 - gdk: add new device types (GDK_SOURCE_TOUCHSCREEN, GDK_SOURCE_TOUCHPAD) #672316 - Flickering/redraw issues in multi stage Many thanks to: Piotr Drąg, Chun-wei Fan, Daniel Mustieles, Fran Diéguez, Matej Urbančič, Nilamdyuti Goswami, Alexander Shopov, Bruce Cowan, Florian Müllner, Gil Forcada, Ihar Hrachyshka, Stefano Facchini, Мирослав Николић, Adam Matoušek, Antonio Fernandes C.

Instead of requiring a full object to compute an easing function out of a linear progress coming from ClutterTimeline, we should have this functionality on ClutterTimeline itself. Since ClutterAlpha is still exposed in API that we cannot deprecate (such as virtual functions) we cannot deprecate it fully, and we'll have to wait until the 2.0 API bump to get rid of it. - Fix ClutterBoxLayout allocation Since the update of the box layout algorithm there have been a bunch of regressions; now the layout works as intended. - Improve the performance of the shader-based effect in Clutter The effects shipped with Clutter now use the CoglSnippet API internally, which allows efficient generation of the shader code; they also ensure that the shader is generated once per class, and shared across instances. These changes should improve performance when using effects provided by Clutter. - Update the internal usage of Cogl API Clutter should strive to use the Cogl 2.0 API internally and not mix the 1.0 and 2.0 API. - Allow accessing Wayland input devices This is a change that allows Clutter-based toolkits to interact with Wayland in a meaningful way for operations like resize and move. - Add a convenience CLUTTER_BIND_ALL enumeration This allows binding both position and size of an actor when using a ClutterBindConstraint. - Cally updates Use the newly added API to reimplement focus tracking. - Visual Studio project updates - Add clutter_text_coords_to_position() This method roundtrips the position_to_coords() one, and allows retrieving the index of the character at the given actor-relative coordinates. - Documentation updates. - Introspection annotation fixes. • List of bugs fixed since Clutter 1.9.10 [bugzilla.gnome.org] #669730 - actor: Fix and improve add_child_at_index() #669291 - box layout bug when callin the clutter_actor_hide() function #667540 - Desynchronized size between ClutterStageCogl and ClutterStageX11 #670433 - clutter-drop-action: annotation fixes for some signals #670402 - CRITICAL warning when ClutterDragAction has threshold > 0 [bugzilla.clutter-project.org] #2515 - Setting a non-default stage fullscreen before showing it doesn't work Clutter 1.9.10 2012-02-06 =============================================================================== • List of changes since Clutter 1.9.8 - Provide symbolic names for pointer buttons The primary, middle, and secondary pointer buttons now have simple and easy to remember constants that can be used in place of the "magic" numbers. - Add ClutterActorIter A simple API, using a stack allocated opaque structure, for safely and efficiently traverse the children of a ClutterActor. - Fix regression introduced by the default FixedLayout layout manager Existing ClutterActor subclasses using their own layout management should now work exactly like in Clutter 1.8. - Documentation fixes Including introspection annotations fixes. - Updates to the Wayland backend The Wayland client backend is now up to date with the 0.85 release of the Wayland protocol. • Bugs fixed since Clutter 1.9.8 [bugzilla.gnome.org] #668692 - Add symbolic names for left, right and middle buttons #668669 - Add iterator API for ClutterActor #667840 - Add annotations from Vala bindings #669360 - clutter-backend-eglnative.h missing in disted tarball #668951 - Fix warnings when weak_unreffing a finalized object Many thanks to: Rob Bradford, Tristan Van Berkom, Chao-Hsiung Liao, Evan Nemerson, Kerrick Staley, Matej Urbančič Clutter 1.9.8 2012-01-24 =============================================================================== • List of changes since Clutter 1.9.6 - Fix regressions in users of deprecated API Also, allow to mix the new Actor API with the old Container API without breaking. - Add GResource support in ClutterScript GResource is a new infrastructure in GIO that allows to compile resources like UI builder files and image data into a shared library or an executable. A newly added method to ClutterScript makes it possible to load a UI definition from a resource, like it's done for files and data. - Update the Wayland client backend The SHM transport API has changed upstream, and the Clutter backend has been updated to reflect it. Many thanks to: Rob Bradford, Fran Diéguez Clutter 1.9.6 2012-01-19 =============================================================================== • List of changes since Clutter 1.9.4 - Deprecate clutter_actor_show_all() and clutter_actor_hide_all() The latter never did make a lot of sense: hiding the parent will effectively hide the children as well; the former was there only for convenience, but Actors are visible by default. - Gracefully handle existing code The changes in ClutterActor introduced regressions in existing code because of the new functionaly that was introduced to replace deprecated classes like Box and Group. These regressions have hopefully been fixed; Clutter 1.9.6 has been tested with a project as complex as the GNOME Shell. - Fix build with binutils-gold The private dependencies were not used when building Clutter, and this made the Gold linker angry. - Allow tracking of an actor's first and last child ClutterActor has two new properties, :first-child and :last-child; these are read-only properties that can be used by toolkits based on Clutter to track the first and last child whenever they change. - Bump the Cogl dependency The 1.9.4 release depended on Cogl ≥ 1.9.4, but the minimum required version was not bumped along with the changes. • List of bugs fixed since Clutter 1.9.4 [bugzilla.gnome.org] #668137 - FTBFS: pangoft2 check seems to be broken Clutter 1.9.4 2012-01-17 =============================================================================== • List of changes since Clutter 1.9.2 - New scene graph API in ClutterActor ClutterActor now provides the API for adding, removing, and iterating over the list of children; this deprecates most of the ClutterContainer API. ClutterActor implements ClutterContainer as well, which means that all actors can be containers. - Layout management updates ClutterActor now have an horizontal and vertical alignment properties that will be used when added to a parent; a margin has also been added to the ClutterActor class. Both margin and alignment will be automatically managed during the allocation, so they will work out of the box. It is also possible to set a ClutterLayoutManager delegate object on any ClutterActor instance: the LayoutManager will take care of the layout policy for the children of an actor. - Add ClutterTextBuffer The ClutterTextBuffer class provides a storage for the contents of a ClutterText actor; the same instance can be shared across different actors as well. The main use for ClutterTextBuffer is implementing secure memory storage for the contents of a ClutterText in password mode. - Deprecations ClutterGroup, ClutterBox, and ClutterRectangle have been deprecated; their functionality is now available directly in ClutterActor. The old child actor management API in ClutterActor and ClutterContainer has been deprecated as well. Other deprecations include the ClutterStage fog-related properties and API; the ClutterContainer.sort_depth_order(), raise(), and lower() virtual functions; the internal child push and pop methods on ClutterActor. - ClutterTimeline can parse markers from ClutterScript Markers can now be defined inside ClutterScript, and a ClutterTimeline will be able to automatically add them from a UI definition. - Add a diagnostic mode Similar to the GLib diagnostic mode, Clutter now supports an environment variable that will print out diagnostic messages for deprecations and warnings that can only be detected at run-time. - Wayland backend updates The wayland backend now tracks the latest API changes in the client API, and Clutter now provides a Wayland surface actor that allows to write Wayland compositors, similarly to the X11TexturePixmap actor for the X11 backend. • List of bugs fixed since Clutter 1.9.2 [bugzilla.gnome.org] #665040 - The offscreen effect always recreates the texture if create_texture() is overridden to change the size #665052 - The internal effects should queue a repaint on the effect not on the actor when a property changes #664996 - clutter_state_set_key (allow-none) #664336 - path: Fix introspection annotations #664252 - in case GLSL shader fails to compile clutter-shader-effect.c should print out position in source code #664582 - lookingGlass: Fix global key press handler #660997 - Make _clutter_actor_queue_redraw_with_clip or an equivalent public Many thanks to: Chun-wei Fan, Robert Bragg, Rob Bradford, Neil Roberts, Bastian Winkler, Fran Diéguez, Jasper St. Pierre, Matej Urbančič, Piotr Drąg, Alexander Shopov, Bastien Nocera, Daniel Mustieles, Jeremy Moles, Jovan Naumovski, Kjartan Maraas, Lucian Adrian Grijincu, Manuel Osdoba, Ryan Lortie Clutter 1.9.2 2011-11-22 =============================================================================== • List of changes since Clutter 1.8 - Multi-backend build, and run-time backend selection Clutter can be built with support for multiple backends in the same shared library; the backend singleton is determined at run-time, either with the default backend for the platform, or using the value of the CLUTTER_BACKEND environment variable. - GDK windowing system backend A new backend has been added, which uses the GDK API for creating the drawing surface, as well as receiving the windowing system and input events. - Show a hint when ClutterText is in password mode If the password-hint-time ClutterSettings property is set to a non zero value, the last character entered inside a ClutterText actor when in password mode will be shown in plain for the duration of the timeout, before being replaced by the glyph chosen as the password character. - Improve Windows build support Clutter now provides project files to build the library using Visual Studio 9 and Visual Studio 10. Also, the scripts to build Clutter using MinGW have been improved. - Remove the requirement for using clutter_threads_init() Threads are initialized by default (depending on the platform), so there is no need to call clutter_threads_init(). - Deprecate the default ClutterStage The semantics of the default Stage were not obvious, and had the tendency to confuse the user. - Move the deprecated headers into their own directory This should help developers identify the deprecated API. - Change deprecation policy Deprecated functions are now marked using compiler annotations, instead of being forcibly disabled through pre-processor directives from the headers. Deprecations will cause compiler warnings, and thus are enabled by default. If you're building your project with compiler flags that consider every warning a fatal error, you can use the symbol CLUTTER_DISABLE_DEPRECATION_WARNINGS to disable the deprecation warnings. - Translation updates Portuguese, Assamese, Punjabi, Tamil, Oriya, Telugu, French, German, Danish, Traditional Chinese (Hong Kong and Taiwan), Catalan, Esperanto, Lithuanian, Galician, Norwegian bokmål, Slovenian, Hebrew, Bulgarian. • List of bugs fixed since Clutter 1.8 652588 - add support for password hint in ClutterText 659625 - mingw32: Update the build script to compile 1.8.0 659601 - offscreen effects on children of containers also with an offscreen effect get a wrong viewport 659928 - Two strings are not marked as translatable 659893 - clutter-main: Reword translator comment for default:LTR 656663 - Remove internal usage of ClutterGeometry in StageWindow 660354 - Add paint-deform-tiles option to CLUTTER_DEBUG 660471 - ClutterActor: Add clutter_actor_has_effects 660512 - ClutterShaderEffect recompiles the shader for every instance 660623 - clutter-actor-meta: Fix _clutter_meta_group_has_metas_no_internal 660985 - memory leak in clutter_box_layout.c 661015 - Add clutter_unicode_to_keyval function 660786 - Deprecate clutter_[sg]et_font_flags() 661887 - auto-resize of ClutterCairoTexture does not work correctly 657434 - Add a GDK backend to Clutter 663332 - orca reads my password in gnome-shell policykit dialogs 663594 - Minor whitespace parsing bug in clutter_color_from_string 663733 - clutter-stage-x11: Make sure to set geometry x and y 651718 - Make tests work on platforms supporting only a single stage 663999 - The removal of per-backend CLUTTER_VBLANK envvar had unwanted cruft in the Win32 backend 663720 - DeformEffect: Avoid redrawing actors on vertices invalidation 663636 - Use newer Cogl API in ClutterDeformEffect Special thanks to Chun-wei Fan, for building, testing, and keeping up to date the Visual Studio project files.

Clutter 1.7.90 2011-09-12 =============================================================================== • List of changes since Clutter 1.7.14 - Make sure that setting :use-markup does not depend on the order Setting the :use-markup property should yield the same results regardless of whether the :text property is also set before or after. This applies to ClutterText defined using ClutterScript as well. - Protect against multiple unrealize call on ClutterStage This should fix a segmentation fault in clutter-gtk when unrealize() is called multiple times on an already unrealized stage. - Fortify ATK event listener Make sure that we subscribe only to the events we want to, and avoid warnings caused by AT-SPI, as well as a leak. - Documentation fixes - Translation updates Indonesian, British English, Brazilian Portuguese, Oriya, Polish, Latvian, Hindi, Danish, Chinese (Simplified), Lithuanian, Turkish, Russian, Spanish, Asturian. • List of bugs fixed since Clutter 1.7.14 [bugzilla.gnome.org] #651940 - "use-markup" is ignored when set after "text" #658721 - cally: Fix up event listener registration minimally [bugzilla.clutter-project.org] #2629 - ClutterText thinks priv->text can be NULL, but it can't Many thanks to: Muhammet Kara, Andika Triwidada, Manoj Kumar Giri, Piotr Drąg, Aurimas Černius, Bruce Cowan, Edvaldo de Souza Cruz, Jorge González, Kenneth Nielsen, Matthias Clasen, Neil Roberts, Og B. Maciel, Rajesh Ranjan, Ray Wang, Rudolfs Mazurs, Xandru Armesto, Yuri Myasoedov Clutter 1.7.14 2011-09-05 =============================================================================== • List of changes since Clutter 1.7.12 - Use newer version of ATK Cally now depends on the latest version of ATK, to reduce the amount of ad hoc code needed and to use newer features that simplify the implementation of accessible objects in Clutter. - Allow using Layout Managers with generic containers Layout managers should not assume that they are allocating the whole area available from the Actor using them; this allows actors that support concepts like padding or margin to use a LayoutManager internally for its children. - Cookbook updates Add a recipe on how to bind a ClutterState to the signals of objects defined in ClutterScript. We also install the cookbook examples inside the $datadir/clutter-1.0/cookbook/examples directory. - Improve examples in the API reference Some of the interactive test suite units are actually good examples of how to use the Clutter API; we can use the XInclude tags to include the source code inside the API reference. - Ensure thread safety of the repaint functions add/removal Fix a long standing issue where adding or removing repaint functions was not acquiring a lock; now it's safe to manipulate the repaint functions list from different threads. - Make the ClutterText:line-wrap property work again In 1.2 the :line-wrap property was broken, and ClutterText would paint a PangoLayout wrapping until it fit the height of the allocation regardless of whether the :line-wrap property was set to FALSE or TRUE. Now we clip the PangoLayout before rendering it, if the :line-wrap property is set to FALSE and there is no ellipsization policy set. - Disable redirection to offscreen buffer by default Whenever a ClutterActor with children was not fully opaque, the actor was redirected to an FBO, to perform correct opacity computations. Sadly, this can lead to 3x slowdowns, given the amount of framebuffer objects created and the state changes that have to be performed. We decided to turn off this feature by default, to avoid the performance hit. It is still possible to enable this feature on a per-actor basis, though, and will work to reduce the hit in future versions of Cogl, Clutter and the drivers. • List of bugs fixed since Clutter 1.7.12 [bugzilla.gnome.org] #657681 - Crash when destroying an actor while dragging it [bugzilla.clutter-project.org] #2339 - ClutterText in 1.4 line-wraps even if line-wrap is disabled Many thanks to: Alejandro Piñeiro, Shankar Prasad, Chao-Hsiung Liao, Dan Winship, Daniel Mustieles, Daniel Nylander, Fran Dieguez, Marek Černocký, Robert Bragg Clutter 1.7.12 2011-08-29 =============================================================================== • List of changes since Clutter 1.7.10 - Reload the font caches on X11 when the user installs a new font Whenever the user installs a new font inside one of the directories that ware being watched by a session daemon, or changes the fontconfig configuration, the toolkits using FontConfig (either directly or indirectly e.g. through Pango, like Clutter) should listen to the Fontconfig/Timestamp XSETTINGS key and release all the font configuration caches. This allows selecting the newly installed fonts without requiring the user to restart the application. - Allow using "font-description" as a ClutterScript alias for "font-name" ClutterText:font-description allows passing a PangoFontDescription directly to a ClutterText; when defining a ClutterText instance inside a ClutterScript file, :font-description should be an alias for :font-name, which takes a string and converts it to a PangoFontDescription. - Make sure that LayoutManager subclasses take the allocation origin into account when allocating the children A LayoutManager should be resilient against allocations with an origin not positioned at (0, 0); this allows actors using a layout manager instance to munge the box and implement things like margin and padding without the layout manager having knowledge of those concepts. - Build fixes Always link against libm when building Clutter (and its tests); don't rely on libraries lower on the stack to do so. - Documentation fixes • List of bugs fixed since Clutter 1.7.10 [bugzilla.gnome.org] #657529 - Build failure Many thanks to: Robert Bragg, Daniel Mustieles, Fran Dieguez, Kjartan Maraas Clutter 1.7.10 2011-08-15 =============================================================================== • List of changes since Clutter 1.7.8 - Do not update the last paint volume when picking Last minute fix for an issue that was most prominently manifesting itself when using GNOME Shell with Clutter 1.7; this should resolve the issue that dragging icons from the dash left around some stale pixels. - Fix building the tests The performance and micro-benchmark tests did not pick up changes in local dependencies, e.g. under a JHBuild root. • List of bugs fixed since Clutter 1.7.8 [bugzilla.gnome.org] #656588 - Outdated FSF Address in code files Many thanks to: Alejandro Piñeiro, Robert Bragg Clutter 1.7.8 2011-08-15 =============================================================================== • List of changes since Clutter 1.7.6 - Various fixes in Cally Make sure to use Clutter's API and remove old workarounds that were put into place when Cally was a separate project and targeting pre-1.0 API versions of Clutter. - Add ClutterCairoTexture:auto-resize This property makes it easier to create 2D canvas surfaces by tracking the actor's allocation in a backward compatible way. - Add ClutterAnimatable.interpolate_value() This new virtual function deprecates the animate_property() virtual of the Animatable interface, which was sub-optimal in different ways. - Allow using Animatable implementations with ClutterState Thanks to the new interpolate_value() virtual it is now possible to use the Animatable interface with ClutterState; this allows animating action, constraint and effect properties using the same "@" syntax also used by ClutterAnimation and clutter_actor_animate(). - Improve ClutterModel's implementation Avoid a bunch of needless checks, and make sure that the ::row-changed signal is emitted in all cases when a row has been changed through the ClutterModelIter API. The conformance test unit for ClutterModel has also been improved to avoid future regressions. - Improve ClutterStage behaviour on OS X Make sure that the fullscreen, multi-screen and key focusing are well-behaved on OS X, by implementing the correct delegate methods. • List of bugs fixed since Clutter 1.7.6 [bugzilla.gnome.org] #655387 - Missing GObject introspection annotations #655306 - Added windowDidChangeScreen delegate to fix pick errors when window moved to different screen #655311 - Prevent hiding of unrelated application windows when stage returns from fullscreen #655307 - Fix resource leak on subsequent calls to clutter_stage_osx_realize #648633 - gnome-shell notification pop-ups do not emit object:state-changed:showing Many thanks to: Kirk A.

The API as well as the ABI are preserved. - Restore a wider range of Z values for actors The computation for the near and far planes given the perspective transformation used to set up the viewport was broken in 1.7.2, and the distance from the focal point was greatly reduced. This has now been fixed. - Bump up the dependency of Cogl New windowing system API in Cogl required bumping the minimum version to the latest development snapshot, 1.7.2. - Add ClutterDropAction The ClutterDropAction is an action for allowing ClutterActors to react when an actor being dragged through ClutterDragAction crosses, or is dropped over, them. - Add a performance test suite This suite is an addition to our conformance and interactive test suites; the infrastructure can be used by buildbots and report tools to track performance regressions across various commits. - Documentation and annotation fixes - Build fixes • List of bug fixes since Clutter 1.7.2 [bugzilla.gnome.org] #650329 - ClutterModifierType: Port fix from GDK to clutter's GDK copy #652566 - Clutter-CRITICAL **: _clutter_stage_get_window: assertion `CLUTTER_IS_STAGE (stage)' failed #651784 - transition=spin / transition=spin-text is broken in pinpoint with Clutter master #652842 - Add a Drop action #653066 - ClutterDragAction does not support multiple pointers #653307 - Change the signature of ClutterTexture::load-finished to give a GError, instead of a gpointer #653607 - Arrays not annotated as such for introspection bindings #651079 - ClutterText "blinks" when deleting text after going out of bounds #650675 - clutter-media: mention the asynchronous behavior of set_playing() [buzgilla.clutter-project.org] #2625 - The furthest visible z value is really low Many thanks to: Robert Bragg, Neil Roberts, Peter Ward, Colin Walters, Daniel Mustieles, Jasper St. Pierre, Samuel Degrande, Øyvind Kolås Clutter 1.7.2 2011-06-13 =============================================================================== • List of changes since Clutter 1.6.0 - Cogl moved out of tree The Clutter OpenGL abstraction library has been moved to a separate repository and can be used as a stand-alone shared library. Clutter has been modified to depend on Cogl's experimental API. - Correctly composite non fully opaque children Non fully opauqe actors with non fully opaque children will automatically redirect children paint operations to offscreen buffers, which allow correct composition taking into account the overall opacity of the scene's sub-graph. The same mechanism can be used to create a paint cache, and paint that cache when the actor or its children do not change, instead of painting the whole sub-graph again. - Allow connecting signals to ClutterState states in ClutterScript When defining a scene using ClutterScript it's possible to directly connect a state inside a ClutterState object (both defined in ClutterScript or in code) to an object's signal, without using an explicit signal handler in the code. - Long-press handling in ClutterClickAction ClutterClickAction will detect a long-press gesture and emit signals to query, activation and cancellation. - Added ClutterGestureAction and ClutterSwipeAction ClutterGestureAction is a generic "pointer gesture" action; it doesn't provide an implementation: it's up to the developer to add the gesture recognition code. ClutterSwipeAction is a GestureAction sub-class that implement the "swipe" gesture. The GestureAction API is already future proof for multi-device/multi-touch, even though the multi-touch isn't currently implemented. - Allow Effects to influence picking Effects that change the geometry of a ClutterActor should also be allowed to change the picking code to make sure that event handling keeps working. ClutterEffect has a new pick() virtual function for these cases. • List of bugs fixes since Clutter 1.6.0 [bugzilla.clutter-project.org] #2257 - clutter fails to link on OS X (10.6) #2447 - atkevents example crashes is the accessibility is disabled #2482 - Cally should avoid to provide a default name and description #2484 - It would be nice to have the old cally Changelog #2553 - new ClutterText API to access the Pango layout offsets #2555 - Per-framebuffer journal causes corruptions #2562 - Crash upon running Clutter-based programs #2585 - add ClutterAction for slide gestures #2588 - Assertion failure in _cogl_pipeline_set_layer_texture_target #2595 - clutter-text: Add a selected-text-color #2597 - CallyStage doesn't have a proper parent #2599 - The paint volume for ClutterText is wrong #2602 - Expose events ignored when doing clipped redraws #2610 - Add recipe about implementing a ClutterEffect #2619 - Removes the addition of the .exe extension to unit-test scripts, on win32. #2620 - _cogl_offscreen_new_to_texture_full() leaks reference when failing #2621 - Clutter segfaults if you queue a redraw of an unmapped actor inside the notify::mapped callback #2631 - [PATCH] Enable evdev ClutterInputDevice objects on creation, as the other backends do #2632 - [PATCH] GL_IMG_TEXTURE_NPOT enables non-power-of-two features #2633 - Make the pick id pool a per-Stage resource #2640 - [patch] allow single-bit imprecision in some conformance tests #2644 - Quartz backend: "Bare" modifier keypresses not generating events #2652 - clutter_actor_queue_redraw() on destroyed stage #2655 - segfault when disposing a slave device without a master #2656 - Clutter can crash when destroying a stage from an event #2667 - git head won't build under Win32 [bugzilla.gnome.org] #650665 - CallyActor shouldn't add by default "press", "release" and "click" #647875 - Use Cairo to dump the pick buffers #647876 - Make the pick if pool a per-Stage resource #650487 - Sync allocation in ClutterBoxLayout with the one in GtkBox #650597 - clutter-id-pool: fix warning on bad pick #650650 - clutter-offscreen-effect: use target size when setting up the viewport #651700 - Give a chance to effects for running when picking #652129 - Use "const" instead of G_CONST_RETURN Many thanks to: Neil Roberts, Robert Bragg, nobled, Daniel Mustieles, Elliot Smith, Matej Urbančič, Alejandro Piñeiro, Chris Lord, Marek Černocký, Tomeu Vizoso, Jasper St. Pierre, James Athey, Piotr Drąg, Øyvind Kolås, Adam Jackson, Andrej Žnidaršič, Kjartan Maraas, Adel Gadllah, Alexandre Franke, Christian Kirbach, Craig R.

The support for XI and XI2 must still be explicitly enabled by the developer, but it is now compiled in by default. It can be disabled at compile time by passing --disable-xinput to the configure script. » Clean up the unintentionally leaked internal symbols in the X11 and GLX backends. » Allow defining the contents of the rows of a ListModel using ClutterScript.

Taylor, Piotr Drąg, Roland Peffer Clutter 1.5.2 (04/10/2010) =============================================================================== • List of changes since Clutter 1.4.0 » Add API to ClutterActor to allow any actor to define its 3D paint volume and its stage-relative 2D bounding box; the paint volume is the 3D space occupied by an actor during the paint sequence. This allows better sizing of the FBOs, and opens the door to scenegraph culling and accurate clipped redraws. The mechanism is opt-in: actors have to implement the get_paint_volume() virtual function. Callbacks attached to the ::paint signal will also disable any culling and clipped redraw in place internally. » Plug a leak in ClutterActor by disposing all constraints. » Rework the build system to be as non-recursive as possible; this should speed up the build of Clutter, and makes the build layout easier to understand and update. » Remove the internal copy of JSON-GLib; the internal copy was falling behind at a spectacular level, and it was actually making the build rather complicated - also by adding an unwanted, but needed, introspection data generation. The required JSON-GLib has also been bumped to the new stable release, 0.12.0. » Use g_object_install_properties() with GLib 2.26. » Implement ClutterContainer::child-notify, which slipped through the cracks of many development cycles without anyone noticing. » Document and test clutter_actor_contains(), especially the corner cases. » Plug a leak in CoglTexture2DSliced. » Plug a leak in ClutterAnimator's handling of timelines. » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable errors when the GLX pixmap is destroyed behind Cogl's back.

Both mechanisms are also throttled to avoid taking all resources when using them in a compositor like Mutter. » Use (and cache) fragment shaders instead of texture combiners inside Cogl materials. Cogl will automatically fall back from GLSL to ARBfp to fixed functions depending on the level of support of the underlying GL implementation. » Implement a new design for materials; this allows scaling up the number of materials in a scene, and also makes copying materials less expensive. » Make Cogl materials responsible for depth testing, and add new experimental API. » Use the (modified) GLU tesselator to draw paths to a vertex buffer object instead of using the stencil buffer, or the scanline rasterizer on platforms without a stencil buffer. » Add ClutterDeformEffect, a base class for effects that deform an actor's geometry when painting it; ClutterPageTurnEffect is an implementation of a "page curl" deformation using the DeformEffect API. » Always use scissoring when clipping, to reduce the amount of buffer that has to be cleared. » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting a constructor property; the default remains fragment shader. » Remove the button of the press event from the DragAction::drag-begin and DragAction::drag-end signals. This is an API break from 1.3.4. » Do not promote clipped redraws to full redraws. » Improve the consistency of the default state name in ClutterState, both in the API and in the serialization format. » Fix a rounding error with the Text layout size. » Add utility functions for CoglMatrix and CoglColor. » Avoid a re-allocation cycle warning when resizing the surface of a CairoTexture actor from within the allocate() implementation. » Do not add the GL libraries for the EGL X11 backend. » Add more checks for size of data passed to the shader types GValue functions. » Add width and height to the BindConstraint. » Parse actions, constraints and effects inside an actor definition for ClutterScript. » Merge the code of native and x11 backends for EGL into a single backend; also allow creating GL context with the EGL backend. » Use XSETTINGS to set up the backend configuration options, like the font name, resolution, font options and double click options, on X11; this also allows ClutterText actors created using the default font name to be updated when the font name and options change; similarly, this allows ClutterUnits to be updated when the screen resolution changes. » Implement the texture_from_pixmap extension support inside Cogl itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap. » Documentation improvements in the API reference and in the cookbook. » Use the -Bsymbolic-functions linker option on supported platforms to avoid intra-library PLT jumps. » Fix painting transparent stages on X11 using the :use-alpha property of ClutterStage. » Fix emission of scroll events on Windows.

Many thanks to: José Dapena Paz Neil Roberts Owen W. Taylor Øyvind Kolås Clutter 1.2.0 (02/03/2010) =============================================================================== • List of changes since Clutter 1.1.14 » Improve the Animator API for consistency, and the implementation to match the intended behaviour, as documented » Add initial (and internal) support for queueing clipped region updates and let the GLX texture-from-pixmap actor take advantage of it » Support any pixel format in cogl_read_pixels() » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic arguments lists » Consistently use :min-width and :min-height inside the Stage to define the minimum size of the Stage window » Implement the Scriptable interface for ClutterModel sub-classes; this allows setting ClutterModel columns (both types and names) in ClutterScript definitions » Add support for unsigned integer indices in the VertexBuffer API » Documentation fixes for Clutter: the coverage is now 100% » Fixes for the EGL native backend » Require libtool >= 2.2.6 » Improve tests coverage Many thanks to: Neil Roberts Øyvind Kolås Robert Bragg Bastian Winkler Chris Lord Owen W.

Many thanks to: Neil Roberts Halton Huo Clutter 1.1.8 (08/02/2010) =============================================================================== • List of changes since Clutter 1.1.6 » Added ClutterAnimator, a class that allows defining complex implicit animations involving multiple actors and states; this class is mostly meant to be used through the ClutterScript definition format, but it provides a convenience C API for easily building animations. » New experimental COGL API to expose "hardware" buffers such as PBOs or drm surfaces. This API can be used, for instance, to make texture uploading faster. » Fixed the issues with resizable stages getting a 1x1 window with the X11 backends » Expose input devices for every event; by default, X11 and Windows backends expose the core devices only. » Add the ClutterStage:key-focus property, for key focus tracking. » Allow setting transformable value types in ClutterAnimation when calling clutter_animation_bind() and clutter_animation_update(). » Delay the creation of the default Stage until clutter_stage_get_default() is actually called; this reduces the work of clutter_init(). » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText » Improve the extendability of CoglTexture with internal backends. » Add implicit texture atlasing; Cogl will try to put every texture inside the same texture atlas by default, to avoid state changes in the driver and (hopefully) improve performance. » Fix notification of the cursor and selection changes in ClutterText; this improves the usage of Clutter from A11Y toolkits. » Do not wait for a frame if the system clock goes backwards. » Fix the dirtying of the clip state; this unbreaks cogl_path_fill(). » Documentation and build fixes. Many thanks to: Neil Roberts Chris Lord Damien Lespiau Alejandro Piñeiro Jussi Kukkonen Kristian Høgsberg Robert Bragg Øyvind Kolås Clutter 1.1.6 (18/01/2010) =============================================================================== • List of changes since Clutter 1.1.4 » Some fixes for the Win32 backend (bug #1905). » Profiling support via the UProf library. Configure with --enable-profile to get a report after each Clutter application is run. » Improved conformance tests with coverage reports via gcov. » ClutterTexture no longer tries to read back texture data into g_malloc'd memory on unrealize (bug #1842). » The CGL_• defines from cogl-defines.h have been removed. These should not have been used by any applications, but if they were being used then please replace them either with the Cogl enums or with the appropriate GL_• enum if you are using GL directly. » Added a delete-event signal to the stage. » Fix for using cogl_rectangle with different texture coordinates for multiple layers (bug #1937). » Fix for using stencil and depth buffers in FBOs on Intel drivers in Mesa (bug #1873). » Support for subtitles in ClutterMedia. » ClutterGLX will now use an RGB visual by default. For applications (and toolkit integration libraries) that want to enable the ClutterStage:use-alpha property there is a new function: clutter_x11_set_use_argb_visual(). » Fix ClutterText to allow using Pango markup and attributes in the same actor (bug #1940). Many thanks to: Alejandro Piñeiro Damien Lespiau Emmanuele Bassi Gord Allot Halton Huo Robert Bragg Samuel Degrande Clutter 1.1.4 (03/01/2010) =============================================================================== • List of changes since Clutter 1.1.2 » Update the ClutterScript parser to be more resilient, and support constructor and ChildMeta properties. The parser also respects the order of the properties in the UI definitions when applying them, and will apply the properties of an Actor after building the scene graph. » Simplified the implementation of LayoutManager sub-classes, and added support for animating a layout manager. » Allow short-circuiting some layout operations by setting a specific flag on ClutterActor. » Improve caching of the preferred size of a ClutterActor. » Allow declaring "internal children" for a ClutterContainer implementation: the memory management of these actors will be deferred entirely to the Container. » Let the ClutterStage honour the :opacity property and the alpha component of the stage color. This requires support in the Clutter backend used. » Improve Windows and OSX backends. » Simplify the feature detection code for OpenGL; this also reduced the required OpenGL version to 1.2. » Improve the matrix stack handling code. The matrices can be debugged by using the COGL_DEBUG environment variable, assuming that Clutter was compiled with the right configure-time switch. » Improve COGL API for draw buffers, and for offscreen buffer support. » Add support for text direction to ClutterActor. » Documentation, introspection and build fixes. Many thanks to: Robert Bragg Neil Roberts Damien Lespiau Joshua Lock Bastian Winkler Rob Bradford Samuel Degrande Christian Persch Colin Walters Johan Bilien Raymond Liu Tim Horton Clutter 1.1.2 (23/10/2009) =============================================================================== • List of changes since Clutter 1.0 » Add ClutterLayoutManager, an abstract proxy class for easily writing layout management policies; also add ClutterLayoutMeta, a class for storing layout properties. » Add ClutterBox, a generic container actor that relies on a ClutterLayoutManager instance to manage the layout of its children. » Add the following layout managers: - ClutterFixedLayout - a layout manager implementing the policy used by ClutterGroup - ClutterBinLayout - a layout manager for packing actors as layers inside the same area, with per-actor alignment - ClutterFlowLayout - a layout manager arranging actors as a reflowing grid - ClutterBoxLayout - a layout manager arranging actors as a single line » Remove the requirement for the backend-specific implementation of ClutterStage to be a ClutterActor: a Stage implementation must only implement the ClutterStageWindow interface. This cleans up the backend code. » COGL source tree clean up and rationalization; COGL now knows the platform, and not only the driver (GL or GLES) so we can migrate part of the low-level backend code from Clutter to COGL where it makes sense. » Remove code duplication across whole COGL. » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter have been fixed and confirmed working. » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options dumps the contents of each pick() buffer into a PNG file, for debugging purposes. » Allow interpolating intervals of ClutterUnits for animating unit-based properties. » Increase strictness and correctness of the ClutterUnits grammar parser. » Add GValue transformation functions for ClutterPath to and from a string. » Fix word movement in ClutterText; implement GObject getter for :use-markup; emit notification for :position; decouple the :text property from the :use-markup property. » Do not queue redraws or relayouts on actors currently being destroyed. » Support #rrggbb and #rgb notations for ClutterColor. » Multiple bug fixes. » Provide _NET_WM_PID on the X11 stage implementation. » Documentation and Introspection annotation fixes. » Add test units for the ClutterActor size requesition. » Build fixes. » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall back to Shave on older Automake versions.

Many thanks to: Geoff Gustafson Michael Mortensen Owen W. Taylor Clutter 0.9.8 (17/07/2009) =============================================================================== • List of changes since 0.9.6 » Add more introspection annotations for language bindings. » Fix a bug in clutter_animation_set_alpha(), which also broke the clutter_actor_animate_with_alpha() function. » Check if the stage requires a relayout before showing it; this fixes a bug in the X11-based backends, especially under compositing window managers, where a 640x480 window would flicker before the default stage was shown for the first time. » Performance fixes for Cogl. » Sliced textures were broken by the COGL journalling. » Use the redraw cycle when asynchronously loading textures from files. » Miscellaneous compilation fixes for the OS X and Windows backends. » Allow querying from within the paint function of an Actor whether the actor is currently being directly painted or by a Clone actor. » In the GLX backend, when using the non-implicit sync-to-vblank inside glXSwapBuffers(), call glFinish() to avoid potential tearing. Many thanks to: Colin Walters Evan Martin Marcos Owen W. Taylor Xu Li Clutter 0.9.6 (01/07/2009) =============================================================================== • List of changes since 0.9.4: » Allow the manipulation of the actor's transformation matrix, so that is is possible to apply additional transformations in a way that is compatible with the transformations already applied by the scene graph. » Fix a race in the X11 backend that happened between resizing the stage drawable and the call to glViewport(). » Merge the cogl-journal-batching branch; this branch implements batching the geometry of the elements of the scene graph before sending it to OpenGL, thus minimizing the number of state changes and improving the overall performance of Clutter-based applications. » Add more debugging states for Clutter and COGL, which allow the developer to track the state of the journal; to check the VBO fallback paths; to disable picking for reliable profiling; to disable software-side matrix transformations in favour of the driver/GPU ones. » Improve the ability to "break out" of COGL by using gl_begin/gl_end semantics; applications that drop into raw GL are, though, ignoring all the caching performed by COGL and might incur in performance issues. » Fixed the :load-async and :load-data-async properties of Texture by removing the unneeded G_PARAM_CONSTRUCT flag. » Added an initial migration guide that shows the porting process from older releases of Clutter to the 1.0 API; the first chapter deals with the migration from ClutterEffect to the new implicit animations API. » Fixed MT-safety for the master clock. Many thanks to: Ole André Vadla Ravnås Tim Horton Clutter 0.9.4 (19/06/2009) =============================================================================== • List of changes since 0.9.2: » Set the layout height in ClutterText, so that wrapping and ellipsization work correctly to fill all the allocated area. » Remove all the units-based API, and migrate all the positional and dimensional accessors to use floating point values when dealing with pixels. All the properties dealing with pixels now that a floating point value as well. » Add the ability to track wether an actor is going to be painted or not, using the "mapped" flag. This also allows Clutter to be more strict in the handling of the scenegraph, ensuring correctness and avoiding wasting resources on nodes that won't be painted. » Add debugging facilities for COGL, similar to those of Clutter; through them is also possible to have an on screen debugging mode that shows the boundaries of each rectangle sent to the GPU. » Rework "units" into real logical distance units that can be converted between millimeters, typographic points and ems into pixels. » Simplify the Animation class to avoid redundancy and the possibility of it going out of sync with the Timeline and Alpha instances it uses. » Move every operation into a single "master clock" source that advances the timelines, dispatches events and redraws the stages in a predictable sequence, thus avoiding unneeded redraws. The default is to follow the sync-to-vblank cycle, if it is supported by the drivers. » Cache the glyphs geometry into a vertex buffer object to avoid resubmitting too much information to the GPU. » Rework the behaviour of ClutterModel when a filter is applied. » Allow submitting premultiplied texture data; this removes the need for unpremultiplying data in CairoTexture. » Add a simple API for submitting blending and texture combining modes through a string description. » Move Timelines to pure time-based objects. » Lots of performance improvements. » Removal of all the deprecated API. » Removal of all the fixed point entry points. » Lots of documentation fixes - the coverage is now 99% of the exported 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL. » Generate the GObject Introspection data for both Clutter and COGL at build time. » Build environment fixes.

Merge branch 'async-texture-thread-pool' Clutter 0.9.0 (30/01/2009) =============================================================================== • List of changes between 0.8.6 and 0.9.0 » ClutterText is a new actor allowing text display, text editing both in multi-line and single-line modes, and text selection using the pointer devices and the keyboard. ClutterText supercedes both ClutterLabel and ClutterEntry. » ClutterClone is a new actor that allows cloning of other actors, both simple and composite. ClutterClone supercedes ClutterCloneTexture. » ClutterBindingPool is a new API that allows to easily add key bindings to an actor. » ClutterAnimation is a new API for implicit animations, similar to the tweening API used in toolkits like jQuery, Tween and Flash. This new API supercedes the ClutterEffect API. » ClutterAlpha uses "animation modes" instead of raw function pointers; it is still possible to pass alpha functions. The alpha functions provided by Clutter have been removed from the public API. It is possible to register global alpha functions and use them though a logical id. » The interval of the ClutterAlpha:alpha property has been changed to a floating point value in the [ -1.0, 2.0 ] range; this allowed the addition of "overshooting" easing modes. » COGL now supports backface culling. » The COGL-based Pango renderer is public API and it is accessible to developers. It is also possible to access the PangoContext used by Clutter in order to create PangoLayouts to render text. » The ClutterFixed API has been moved to COGL. » COGL does not depend on Clutter data types anymore. » The ClutterMedia interface has been overhauled: implementations now must only override the interface properties. The ranges of some properties have been changed to normalized values. » COGL now exposes only floating point entry points, and reserves the eventual conversion to fixed point only when needed. The fixed point type and macros are publicly available for developers concerned about floating point operations. » COGL has a new Vertex Attribues API that allows submitting an extensible number of vertex attributes to OpenGL in a way that does not require format conversions and allows fast re-use. » COGL has a new Material API that decouples paths from fills; it is possible to create an arbitrary path and fill it with a COGL texture. The Material API also allows setting multiple texture layers and defining the blend modes and colors. » ClutterTexture has the ability to use a worker thread to asynchronously load an image from a file, as long as the GLib threading support has been enabled prior to calling clutter_init(). » Clutter now supports localization of the help output, and it also supports globally setting the text direction for non left to right locales. » ClutterCairoTexture is a new actor that allows using Cairo to draw on a ClutterTexture; since Cairo does not have an OpenGL backend, the drawing is not hardware accelerated. » Clutter has a unit testing suite, based on the GLib unit test framework, which can be used to track regressions. » A ClutterPath object has been added, and it is used by the BehaviourPath. The Path object allows defining paths using a set of coordinates and operations. A Path can be "painted" either using COGL primitives or using Cairo primitives, allowing an easier way to paint non-rectangular shaped actors. » ClutterInterval is a simple object, used by ClutterAnimation, that describes an interval between two values, and interpolates between the initial and final values of the interval. • List of bugs fixed since 0.8.6 » #835 -

This allows defining directories to store the images to be loaded by a ClutterTexture. » Fix the GLES 1.1 support. » Warn if no usable pointer device are available on X11 backends. » Improve the request for the best pixel format on win32. » Fix a regression when sizing the ClutterStage on backends that only support fixed size stages; now setting any size will result in Clutter ignoring the request, like it happened in Clutter 0.6. » Add a method to ClutterBackend to retrieve the display size. » Fix clutter_sinx() for angles > CFX_2PI - CFX_ONE. • List of bugs fixed » #833 - ClutterEntry should clip glyphs rather than itself » #858 - Support for multiple devices (using XINPUT) » #879 - sampler2DRect used by test-shader.c doen't work with non-rect textures » #979 - Wrong call convension for SwapIntervalProc in win32 backend » #987 - clutter-event.c c99 variable declaration » #988 - cursor position wrong with multibyte invisible char » #989 - Add a search path for clutter script assets Clutter 0.7.2 (23/06/2008), "Kedoke" =============================================================================== • List of changes between 0.7.0 and 0.7.2 » ClutterTexture has a new :keep-aspect-ratio property; when it is set to TRUE the texture will return a preferred width maintaining the aspect ratio with the given height and a preferred height maintaining the aspect ratio with the given width. This allows to set the width or the height and have the texture automatically request the height or the width respectively while maintaining the aspect ratio of the original image. » Added XINPUT support on the X11 backends; this provides an initial support for multiple input devices. The API is X11-specific, and provides support for querying at run-time support for XINPUT, for getting a list of input devices and for getting the type of each input device. » The 'fruity' backend also features multiple device support. • List of bugs fixed » #816 - clutter_actor_request_coords() should take a const box. » #836 - Optimize clutter_label_query_coords() » #905 - Paint cursor directly » #918 - Group doesn't clip if it's children are clipped » #953 - Actors are not hidden before unrealized or disposed » #960 - PangoContext creation code should not be duplicated » #970 - clutter_actor_get_paint_area confusion » #971 - Minor ClutterActor cleanups » #972 - Better parenting » #973 - unreffing ClutterScore may segfault » #981 - clutter_stage_read_pixels temprow fix » #982 - __COGL_GET_CONTEXT MS compiler issue » #984 - pango_clutter_render_layout() declared void Clutter 0.7.0 (13/06/2008), "Booska" =============================================================================== • List of changes between 0.6 and 0.7.0 » COGL, the underlying GL abstraction layer in Clutter, has been completely rewritten from the ground up. Its no longer a conceptual hack but a documented, fully featured library pretty much in its own right. COGL abstracts over Open GL, Open GL ES 1.1 and now OpenGL ES 2.0, providing a smart uniform API over these libraries with various utility features such as texture tiling abstractions, paths and primitive rendering, FBO, shaders, etc. » Clutter now provides an experimental backend for the Apple(tm) iPhone and iPod Touch families of products. » The Windows platform is now natively supported instead of relying on the SDL libraries. The win32 backend is still experimental. » The X11 based backends now feature support for Actors that wrap external X drawables (i.e the texture-from-pixmap extension and fallbacks) » Clutter now seamlessly supports multiple stages on the backends that allow this feature. » The custom Pango renderer has been completely rewritten, now using the more modern and maintained PangoCairo (instead of FT2), and avoids nasty subclassing hacks, supports smooth fast scaling of text, has many edge case issues fixed and it still is very efficient (using a texture glyph cache). It is even a little bit faster. » Better texture support, timeline improvements, ClutterLabel and ClutterEntry improvements, and container child properties are among the new features - too many to fit in the NEWS file. • List of bug fixes » #358 - "window resizing doesn't show scaled stage" » #425 - "COGL enhancements" » #439 - "timing related pong lockup due to timeline_rewind somtimes being ignored by timeline_timeout_func" » #450 - "ClutterScore API enhancements" » #641 - "add markers to timelines" » #666 - "Large font size leads to missing ""W"" and wrong ""J"" character" » #713 - "texture from pixmap" » #791 - "default actors to visible" » #800 - "CLUTTER_ALPHA_EXP_INC overflows" » #804 - "clutter_actor_get_opacity returns composited alpha" » #810 - "100 % CPU load with clutter_main()" » #815 - "Split up request » #816 - "clutter_actor_request_coords() should take a const box." » #822 - "Fix clutter_actor_lower()" » #823 - "Clean-up GLism's in clutter-core (below cogl)" » #824 - "ClutterEntry should handle its own key events" » #825 - "Removes GLisms from clutter-main.c" » #831 - "configure.ac missing osx flavour help" » #834 - "add ability to set anchor in json" » #836 - "Optimize clutter_label_query_coords()" » #839 - "Crash if put cursor over topmost pixel" » #840 - "Implement prepare-paint and finish-paint signals." » #848 - "Events dispatch doesn't work in GLX Xephyr" » #850 - "Impossible to set ClutterRectangle border opacity to a value different from the surface opacity" » #857 - "cogl_color doesn't work in PowerVR PC Viewer" » #860 - "ClutterAlpha leaks" » #864 - "Allow instantiating and subclassing of ClutterStage" » #871 - "Two problems with closing stages" » #873 - "clutter_x11/glx_texture_pixmap issues" » #874 - "Clipping on GL ES" » #875 - "Clutter Label Issues" » #881 - "Timelines require precise system timing" » #882 - "Allow child properties for containers implementing the ClutterContainer interface" » #884 - "Add clutter_alpha_set_closure" » #889 - "Error when building clutter-ivan with eglx" » #891 - "assertion failed when test-behave exits" » #892 - "Incorrect results using rotation-[center|angle] properties" » #894 - "Artifacts with the pango renderer" » #900 - "clutter_actor_lower() and friends do not queue redraw" » #906 - "Implement timing of the events" » #908 - "Support transform from G_TYPE_INT to ClutterUnit" » #909 - "OSX: missing NULL pointer handling" » #910 - "OSX: missing memory pool" » #911 - "OSX: add multistage support" » #912 - "Invalid use of int• as parameter for glGetIntegerv" » #913 - "cogl fails to build on OSX" » #914 - "ClutterEntry is confused about characters vs. bytes" » #915 - "clutter_entry_set_max_length(-1) misbehaves" » #916 - "ClutterKeyEvent:unicode_value is ignored" » #919 - "Replacement pango renderer" » #927 - "Created ports for clutter » #928 - "Reparenting a child that itself is a container doesn't work" » #930 - "add support for quartz imagebackend" » #931 - "suspicious size allocation for pixel data" » #933 - ""X Error of failed request" when attempting to call clutter_actor_request_coords()" » #934 - "Update clutter-tutorial to build with clutter from svn trunk." » #947 - "Destroying a stage is messy" » #948 - "Remove texture rectangle support" » #950 - "AltGr not handled" » #951 - "Fix clutter_entry_init() in trunk" » #952 - "Fix test-textures in trunk" » #953 - "Actors are not hidden before unrealized or disposed" » #955 - "ClutterLabel is missing fallback resolution handling" » #959 - "Multiple minor improvements" » #960 - "PangoContext creation code should not be duplicated" » #961 - "Fails to build on OSX (query/request_coords is gone)" » #964 - """unrealized"" signal of ClutterActor wrongly named" Clutter 0.6.0 (18/02/2008) ========================== • List of changes between 0.5.6 and 0.6.0 » New documentation sections inside the API reference, describing the animation framework. » New API in ClutterActor for computing the actor's vertices in the plane of a given ancestor and accessors to query whether an actor is scaled or rotated • List of bug fixed » #613 - Extend point transformation API » #779 - Rounding error in ClutterBehaviourScale [Havoc Pennington] » #787 - tiled textures are broken » #796 - segmentation fault when setting label text Clutter 0.5.6 (11/02/2008) ========================== • List of changes between 0.5.4 and 0.5.6 » Reverted a last minute change in the depth sorting function of ClutterGroup. » Added the clutter_actor_move_anchor_point() family of functions, which will set the anchor point at the given coordinates while adjusting the actor postion so that the relative position of the actor toward its parent remains the same. » Provide a fallback for finding the Clutter alpha functions inside a UI definition for ClutterScript in case g_module_open() fails. » Add initial Frame Buffer Objects support in ClutterTexture;

It is also possible do describe top-level objects such as timelines and behaviours, and to automatically connect signal handlers to signal names. » ClutterTimelines duration can now be set in milliseconds using the :duration property; the default framerate will be used to compute the actual duration in frames. The default framerate will be set by the backend, and can be overridden by the application. » ClutterTimelines direction can now be set using the :direction property; a timeline can be set to proceed forward or backward, and the direction can also be change while the timeline is still running. » New, experimental OSX backend. » Build environment for MS VisualStudio 2005. » ClutterModel, a generic list-based model object that can be used to implement actors following the Model-Viewer-Controller design pattern. Clutter provides a default implementation of ClutterModel, called ClutterModelDefault and using the GSequence data structure from GLib to optimize insertion and look up. » Add the ability to grab pointer and keyboard events: if an actor is set to have a grab it'll be the only one receiving events until it releases the grab. » Add the ability for an actor to receive the key focus; an actor with key focus will always receive the key events, even if it did not acquire the keyboard grab. » It is now possible to set the GL "fog" (also known as "depth cueing") effect on the ClutterStage; if the fog is enabled, actors farther away from the view point will fade into the stage background color. » Each actor now has an "anchor point", a point defined in the actor's coordinate space that will be used as the origin when scaling and rotation transformations. » Every pixel-based API has been doubled with a corresponding ClutterUnits-based function (postfixed with a '-u'), for instance: clutter_actor_set_position() - clutter_actor_set_positionu() clutter_actor_set_size() - clutter_actor_set_sizeu() clutter_actor_set_depth() - clutter_actor_set_depthu() This allows sub-pixel precision and device independence. » The ClutterLabel actor now tries very hard to provide a sane default size, if no bounding box has been requested; this fixes the :alignment property and allows the addition of the :justify property. » The SDL backend can now be compiled under win32 with MingW; this backend is still marked as experimental. » The OSX backend allows the compilation of Clutter under OS X; this backend is experimental. • List of bugs fixed » #423 - All actors should emit events rather than just the stage » #424 - Interface definition files » #443 - ClutterModel implementation » #480 - Uninitialized variable in path_alpha_to_position() [Gwenole Beauchesne] » #511 - clutter_stage_get_actor_at_pos problem » #512 - clutter window moves when stage actor is scaled » #518 - XEMBED not supported in eglx backend » #519 - Should have an Atom cache initialized on start up » #520 - Delete after multibyte unicode chars in ClutterEntry [Tommi Komulainen] » #522 - Array out of bounds indexing [Tommi Komulainen] » #523 - cogl portability fixes [Tommi Komulainen] » #524 - missing config.h includes [Tommi Komulainen] » #525 - Redundant include in cogl/gl [Tommi Komulainen] » #531 - Extraneous "new-frame" signal generated » #532 - clutter_actor_set_scale_with_gravityx() precision [Gwenole Beauchesne] » #544 - clutter_color_to_hlsx is broken [Neil Roberts] » #546 - ClutterStageState doesn't make sense » #550 - Wanted: Set Actor's position based on center or other edges/corners of quadrangle » #557 - ClutterScript should support complex properties for third party classes » #558 - Unmerge UI definitions » #566 - ClutterEntry does not scroll the text to the right [Gwenole Beauchesne] » #577 - Inconsistent naming of behaviour properties » #580 - Fix call to cogl_enable() [Gwenole Beauchesne] » #582 - api naming inconsistence between clutter_behaviour_path_append_knots and clutter_behaviour_bspline_append » #584 - Typo on clutter_effect_rotate_x documentation page » #592 - Fix build on trunk [Gwenole Beauchesne] » #596 - ClutterTexture tileing logic is a little borked » #597 - ClutterGroups not pickable » #600 - fix ClutterLabel layout computing when no box has been set » #604 - Color param for Label constructor should be const [Jonathon Jongsma] » #606 - enable depth test in GL » #608 - Control motion events frequency » #614 - ClutterActor API inconsistencies » #616 - ClutterTexture doesn't respect width set from clutterscript » #617 - ClutterEffect Improvements » #618 - ClutterScript name/id confusion » #619 - clutter_behavior_rotate angle properties should accept negative values » #628 - clutter_actor_rotate_x() is a setter, not a modifier » #629 - There is no clutter_actor_get_position() » #634 - clutter_behaviour_path_new() documentation unclear » #637 - add depth cueing support to the stage » #645 - Fix crash in clutter_label_new_full() [Gwenole Beauchesne] » #647 - Cannot hide the stage » #648 - Hidden fullscreen stage doesn't come back as fullscreen » #652 - reference needed on actor being source of last motion_event » #661 - clutter_actor_set_width() documentation is vague » #662 - clutter_actor_set_opacity() documentation doesn't describe values » #665 - ClutterBehaviourEllipse tilts are broken » #670 - Fix clutter_container_lower_child() [Gwenole Beauchesne] » #673 - ClutterActor "captured-events" signal documentation wrong » #674 - ClutterActor::get_depth() and set_depth() vfuncs not used [Murray Cumming] » #675 - update subregions of cluttertextures » #678 - ClutterLabel size allocation still bogus Clutter 0.4.0 (07/08/2007) ======================== • List of changes between 0.3.1 and 0.4.0 » Many documentation additions and improvements. » Display DPI now honours on backends its can be queried. » Various big endian related fixes. » ClutterBehaviourEllipse and ClutterBehaviourRotate API and internals improvements. » Add basic tslib support to eglnative backend (for touchscreen events) » clutter_stage_get_actor_at_pos should now work on 16bpp displays. » New ClutterEffect rotation calls. » Allowing user resizing of the stage now optional.

Clutter 0.3 (29/06/2007) ======================== • List of changes between 0.2.3 and 0.3 » Clutter now supports both switchable windowing system and GL backends. Window systems supported include GLX, EGL and SDL. GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is provided by a small basic abstraction layer 'cogl.h'. Cogl is not yet documented - usage external to Clutter is not yet advised. Backends may provide specific command line options. Notes; GLX --- The GLX backend is built by default and is currently the most developed, supported and featured windowing system backend. Only OpenGL is supported via GLX. SDL --- Clutter has experimental support for using SDL. Open GL is supported as is OpenGL ES via Dogles (very experimental). EGL --- Clutter has experimental support for using EGL. Only Open GL ES is supported by EGL. EGL support assumes an EGL implementation running atop X Windows. Open GL ES. ----------- Clutter now has experimental support for Open GL ES. Current known issues; + Unrealising a ClutterTexture will not move pixel data from video into system memory but simply destroy it. + BGRA, YUV Texture data not currently supported. (Use the clutter_feature API to probe for above at runtime) Open Source ES implementations this has been tested against include `Vincent' and `dgles'. Support for commerical implementations may require modifications to the configure.ac script. vincent: http://ogl-es.sourceforge.net/ (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ ) dgles: http://developer.hybrid.fi/dgles/index.html » New ClutterEffect class provides a simplified (and thus less flexible) API wrapping around behaviours, alphas and timelines. » New Behaviours - bspline, ellipsis, rotation. » New built in Alpha functions; CLUTTER_ALPHA_SINE_INC CLUTTER_ALPHA_SINE_DEC CLUTTER_ALPHA_SINE_HALF CLUTTER_ALPHA_SQUARE CLUTTER_ALPHA_SMOOTHSTEP_INC CLUTTER_ALPHA_SMOOTHSTEP_DEC CLUTTER_ALPHA_EXP_INC CLUTTER_ALPHA_EXP_DEC » New Actors and interfaces + ClutterLayout, for writing extended layout support in actors + ClutterContainer, for generic container actors + ClutterBox, ClutterVBox and ClutterHBox layout actors. + ClutterEntry, text entry actor » ClutterTexture now handles BGRA, YUV and premultiplied alpha data. » All internal math now fixed point based. » Clutter now has it own internal event queue. » ClutterStage new features; + Title property for naming in window decorations. + Perspective setting - The stages perspective can now be modified. » New Clutter_actor •project API calls allow for querying of tranformed actor vertices and points. » New Clutter Feature checks. » Initial ClutterUnit implementation for device independant positioning. • List of Bugs fixed » Various issues with very poor performance and Intel drivers. » #138 Fix typo in x rotation transform.
