Taylor, Tomeu Vizoso, Chris Lord, Alexandre Quessy, Evan Nemerson, Elliot Smith Clutter 1.5.6 2010-11-19 =============================================================================== • List of changes since Clutter 1.5.4 » Deprecate ClutterBehaviour and its sub-classes: the same functionality is available using the animation framework. » Add ClutterSnapConstraint, a constraint implementation that snaps together the edges of two actors. » Add ClutterPathConstraint::node-reached. » Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is not used internally any more, and since it's not integrated with the master clock it's of relative use. » Add a named, global color palette. » Add the ClutterTimeline:reverse property, for automatically reversing the direction of a timeline after the emission of the ::completed signal. » Performance improvements in the clip stack. » Do not use pointer grabs in ClutterClickAction. » Improve the internally used Cogl API for primitives, paths and buffers; this is the first step towards Cogl 2.0. » Allow using the COGL_DEBUG environment variable to disable the NPOTs support. » Plug a nasty infinite loop in the XSETTINGS implementation. » Internally rename CoglMaterial to CoglPipeline; this should make it clearer that the API refers to the state of the GPU pipeline. » Add support for clipped redraws on EGL using the NOK_swap_region extension. » Build fixes. » Use the monotonic clock API if compiling against GLib ≥ 2.27.3. » Update examples in the Cookbook. » Add a Cookbook recipe for looping animations. » Add more documentation on Constraints. » Documentation fixes. Translation updates: Italian, Polish Many thanks to: Robert Bragg, Neil Roberts, Elliot Smith, Owen W. Taylor, Damien Lespiau, Lucas Rocha, Maxim Ermilov, Piotr Drąg, Tomeu Vizoso, muflone Clutter 1.5.4 =============================================================================== • List of changes since Clutter 1.5.2 » Add a backend for Wayland. » Depend on GLib ≥ 2.26, Cairo ≥ 1.10. » Do not generate the conformance tests list using the test-conformance binary. » Implement interval progress functions for ActorBox, Vertex, Geometry, Color and Units. » Allow overriding the surface creation in Clutter.CairoTexture. » Add interpolate() method to Clutter.Color. » Add ClutterPathConstraint, a simple constraint that sets the origin of an actor's allocation to follow a ClutterPath. » Plug some memory leaks. » Fix build of the CEx100 and EGL backends. » Fixes for the OSX backend. » Documentation consistency and spell checking fixes. » Build fixes. Translation updates: Andika Triwidada (id), Damien Lespiau (fr), Piotr Drąg (po) Many thanks to: Damien Lespiau, Neil Roberts, Kristian Høgsberg, Andika Triwidada, Ole André Vadla Ravnås, Robert Bragg, Owen W. 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.

Many thanks to: Neil Roberts Elliot Smith Robert Bragg Damien Lespiau José Dapena Paz Owen W. Taylor Clutter 1.3.10 (04/08/2010) =============================================================================== • List of changes since Clutter 1.3.8 » Fix a locale-dependent conversion from double to string when generating ARBfp programs for the materials. » Use the XKB extension on X11 platforms to convert between hardware keys to key symbols. » Documentation fixes in the API reference. » More recipes, with videos and full examples, in the Cookbook. » Add localization support and initial translations of error messages that might be visualized in a user interface. » Improve debugging output. » Fix build of the GLX backend on OSX. » Multiple fixes to the native OSX backend. » Add support for 3D textures in Cogl. » Fix shader-related issues and leaks in the new Material code. » Unify GLSL support in the GL and GLES 2.0 drivers. » Allow specifying an hint to disable clearing the stage before each paint cycle.

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: Robert Bragg Damien Lespiau Neil Roberts Colin Walters Clutter 1.3.2 (24/05/2010) =============================================================================== • List of changes since Clutter 1.2 » Add ActorMeta, a class for run-time composition of actions and constraints on a ClutterActor: » Add ClutterAction, a class for implementing business logic related to event handling. » Add ClutterConstraint, a class for implementing business logic related to sizing and positioning. » ClutterDragAction is an Action sub-class that implements signals and properties for dragging actors. » ClutterAlignConstraint and ClutterBindConstraint are two Constraint sub-classes that allow relative positioning with fixed layout managers. » Add ClutterState, an object for defining state transitions. » Add ClutterBoxLayout:homogeneous property. » Implement retained clip stacks. » Support retained paths. » Add an experimental vector3 API. » Require GLib >= 2.18. » Require Atk >= 1.7. » Make ClutterActor implement AtkImplementor, and allow retrieving an AtkObject from a ClutterActor. » Improve ClutterText's Pango layout caching mechanism. » Fix set up of the GLX_SGI_swap_control extension. » Fix EGLX backend. » Documentation fixes for Clutter and COGL. » Fix the conformance test suite by executing every test unit in a separate process. » Add platform-dependent defines for Cogl. » Update the MingW cross-compilation script. » New recipe in the Cookbook.

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.

[clutter-texture] fixed gtk-doc formatting, and init threads in test. 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 -

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;

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'.
