1 Clutter 1.5.2 (04/10/2010)
2 ===============================================================================
4 • List of changes since Clutter 1.4.0
6 » Add API to ClutterActor to allow any actor to define its 3D paint
7 volume and its stage-relative 2D bounding box; the paint volume is
8 the 3D space occupied by an actor during the paint sequence. This
9 allows better sizing of the FBOs, and opens the door to scenegraph
10 culling and accurate clipped redraws. The mechanism is opt-in: actors
11 have to implement the get_paint_volume() virtual function. Callbacks
12 attached to the ::paint signal will also disable any culling and
13 clipped redraw in place internally.
15 » Plug a leak in ClutterActor by disposing all constraints.
17 » Rework the build system to be as non-recursive as possible; this should
18 speed up the build of Clutter, and makes the build layout easier to
19 understand and update.
21 » Remove the internal copy of JSON-GLib; the internal copy was falling
22 behind at a spectacular level, and it was actually making the build
23 rather complicated - also by adding an unwanted, but needed,
24 introspection data generation. The required JSON-GLib has also been
25 bumped to the new stable release, 0.12.0.
27 » Use g_object_install_properties() with GLib 2.26.
29 » Implement ClutterContainer::child-notify, which slipped through the
30 cracks of many development cycles without anyone noticing.
32 » Document and test clutter_actor_contains(), especially the corner
35 » Plug a leak in CoglTexture2DSliced.
37 » Plug a leak in ClutterAnimator's handling of timelines.
39 » Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
40 errors when the GLX pixmap is destroyed behind Cogl's back.
53 Clutter 1.4.0 (24/09/2010)
54 ===============================================================================
56 • List of changes since Clutter 1.3.14

73 » Documentation and introspection fixes.
86 Clutter 1.3.14 (15/09/2010)
87 ===============================================================================
89 • List of changes since Clutter 1.3.12
91 » Fix applying layout properties from ClutterScript definitions in case
94 » Add a Clutter EGL backend for Intel CEx100 platforms.

97 - texture cross-fading
98 - ClutterScript definitions
101 - reusing complex animations
103 » Add methods to retrieve the clicked button and to force a release
106 » Documentation fixes in the API reference.
108 » Cache a full pick buffer and re-use it in case the scene does not change

117 » Provide introspection data for the X11-specific API, like
118 ClutterX11TexturePixmap
120 » Use a template material for ClutterTexture to minimize the creation of
123 » Split ClutterDragAction:drag-threshold into two, per-axis properties:
124 :x-drag-threshold and :y-drag-threshold.
126 » Allow disabling the -Bsymbolic flag when linking.
128 » Use gettext >= 0.17 to handle the localization.
130 » Flush the framebuffer earlier when drawing the vertex buffers, to fix
131 a crash when dealing with clip stacks.
133 » Make sure ClutterX11TexturePixmap removes the Cogl texture handle before
134 freeing the X11 Pixmap to avoid an error.
136 » Avoid regenerating the CoglMaterial programs too many times.
157 Clutter 1.3.12 (16/08/2010)
158 ===============================================================================
160 • List of changes since Clutter 1.3.10

203 generating ARBfp programs for the materials.
205 » Use the XKB extension on X11 platforms to convert between hardware
208 » Documentation fixes in the API reference.
210 » More recipes, with videos and full examples, in the Cookbook.
212 » Add localization support and initial translations of error messages
213 that might be visualized in a user interface.
215 » Improve debugging output.
217 » Fix build of the GLX backend on OSX.
219 » Multiple fixes to the native OSX backend.

263 » Rename the experimental CoglPixelBuffer API to CoglPixelArray.
265 » Split the clutter_state_change() method into two:
266 clutter_state_set_state(), for animated state changes; and
267 clutter_state_warp_to_state() for immediate state changes.
269 » Documentation and introspection fixes.
283 Clutter 1.3.6 (30/06/2010)
284 ===============================================================================
286 • List of changes since Clutter 1.3.4
288 » Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
289 available, by using EXT_framebuffer_blit. Both mechanisms are also
290 throttled to avoid taking all resources when using them in a compositor
293 » Use (and cache) fragment shaders instead of texture combiners inside
294 Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
295 to fixed functions depending on the level of support of the underlying
298 » Implement a new design for materials; this allows scaling up the
299 number of materials in a scene, and also makes copying materials
302 » Make Cogl materials responsible for depth testing, and add new
305 » Use the (modified) GLU tesselator to draw paths to a vertex buffer
306 object instead of using the stencil buffer, or the scanline rasterizer
307 on platforms without a stencil buffer.
309 » Add ClutterDeformEffect, a base class for effects that deform an
310 actor's geometry when painting it; ClutterPageTurnEffect is an
311 implementation of a "page curl" deformation using the DeformEffect
314 » Always use scissoring when clipping, to reduce the amount of buffer
315 that has to be cleared.
317 » Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
318 a constructor property; the default remains fragment shader.
320 » Remove the button of the press event from the DragAction::drag-begin
321 and DragAction::drag-end signals. This is an API break from 1.3.4.
323 » Do not promote clipped redraws to full redraws.
325 » Improve the consistency of the default state name in ClutterState,
326 both in the API and in the serialization format.
328 » Fix a rounding error with the Text layout size.
330 » Add utility functions for CoglMatrix and CoglColor.
332 » Avoid a re-allocation cycle warning when resizing the surface of
333 a CairoTexture actor from within the allocate() implementation.
335 » Do not add the GL libraries for the EGL X11 backend.
337 » Add more checks for size of data passed to the shader types GValue
340 » Add width and height to the BindConstraint.
342 » Parse actions, constraints and effects inside an actor definition
345 » Merge the code of native and x11 backends for EGL into a single
346 backend; also allow creating GL context with the EGL backend.
348 » Use XSETTINGS to set up the backend configuration options, like
349 the font name, resolution, font options and double click options,
350 on X11; this also allows ClutterText actors created using the
351 default font name to be updated when the font name and options
352 change; similarly, this allows ClutterUnits to be updated when
353 the screen resolution changes.
355 » Implement the texture_from_pixmap extension support inside Cogl
356 itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
358 » Documentation improvements in the API reference and in the cookbook.
360 » Use the -Bsymbolic-functions linker option on supported platforms
361 to avoid intra-library PLT jumps.
363 » Fix painting transparent stages on X11 using the :use-alpha property
366 » Fix emission of scroll events on Windows.
385 Clutter 1.3.4 (07/06/2010)
386 ===============================================================================
388 • List of changes since Clutter 1.3.2
390 » Add ClutterEffect, a ClutterActorMeta sub-class that affects the
391 way an actor paints itself.
393 » Clutter provides a base class for effects painting to an
394 offscreen buffer, and a base class for effects using the
395 GL programmable pipeline (through the GLSL shader language).
397 » Clutter also provides some simple, shader-based effects:
398 ClutterBlurEffect, ClutterColorizeEffect and
399 ClutterDesaturateEffect.
401 » Effects can be applied to any actor, and can also be stacked.
403 » Add ClutterClickAction, an action that provides "button-like"
404 semantics for any ClutterActor.
406 » ClutterDragAction now moves the actor to which it has been applied
407 by default, using a class handler for the ::drag-motion signal.
409 » Add the :pick-with-alpha property to ClutterTexture; this property
410 allows using the alpha channel of a texture when picking it.
412 » Regenerate the mipmaps on COGL textures when a texture is modified.
414 » Documentation and build fixes.
423 Clutter 1.3.2 (24/05/2010)
424 ===============================================================================
426 • List of changes since Clutter 1.2
428 » Add ActorMeta, a class for run-time composition of actions and
429 constraints on a ClutterActor:
431 » Add ClutterAction, a class for implementing business logic
432 related to event handling.
434 » Add ClutterConstraint, a class for implementing business
435 logic related to sizing and positioning.
437 » ClutterDragAction is an Action sub-class that implements
438 signals and properties for dragging actors.
440 » ClutterAlignConstraint and ClutterBindConstraint are two
441 Constraint sub-classes that allow relative positioning
442 with fixed layout managers.
444 » Add ClutterState, an object for defining state transitions.
446 » Add ClutterBoxLayout:homogeneous property.
448 » Implement retained clip stacks.
450 » Support retained paths.
452 » Add an experimental vector3 API.
454 » Require GLib >= 2.18.
456 » Require Atk >= 1.7.
458 » Make ClutterActor implement AtkImplementor, and allow retrieving
459 an AtkObject from a ClutterActor.
461 » Improve ClutterText's Pango layout caching mechanism.
463 » Fix set up of the GLX_SGI_swap_control extension.
467 » Documentation fixes for Clutter and COGL.
469 » Fix the conformance test suite by executing every test unit in
472 » Add platform-dependent defines for Cogl.
474 » Update the MingW cross-compilation script.
476 » New recipe in the Cookbook.
493 Clutter 1.2.2 (15/03/2010)
494 ===============================================================================
496 • List of changes since Clutter 1.2.0
498 » Fix introspection annotations for ClutterBox
500 » Compilation fixes for the EGL native backend
502 » Fix ClutterX11TexturePixmap ::queue-damage-redraw default handler
503 registration to avoid a run-time warning
505 » Handle TEXTURE_RECTANGLE_ARB in the 2D sliced textures, and add
506 a test case for that extension to avoid regressions
508 » Improve the strictness of the JSON parser in the internal copy
509 of JSON-GLib to which we fall back in the absence of the system
512 » Fix a crasher on NVidia drivers when enabling the ARGB visuals
522 Clutter 1.2.0 (02/03/2010)
523 ===============================================================================
525 • List of changes since Clutter 1.1.14
527 » Improve the Animator API for consistency, and the implementation
528 to match the intended behaviour, as documented
530 » Add initial (and internal) support for queueing clipped region updates
531 and let the GLX texture-from-pixmap actor take advantage of it
533 » Support any pixel format in cogl_read_pixels()
535 » Conditionally use G_VALUE_COLLECT_INIT() in functions using variadic
538 » Consistently use :min-width and :min-height inside the Stage to define
539 the minimum size of the Stage window
541 » Implement the Scriptable interface for ClutterModel sub-classes; this
542 allows setting ClutterModel columns (both types and names) in
543 ClutterScript definitions
545 » Add support for unsigned integer indices in the VertexBuffer API
547 » Documentation fixes for Clutter: the coverage is now 100%
549 » Fixes for the EGL native backend
551 » Require libtool >= 2.2.6
553 » Improve tests coverage

580 from a foreign GL texture
582 » Split Clutter's debug annotations from the pick and paint mode
583 behavioural modifiers
585 » Improve the usage of the CLUTTER_ACTOR_NO_LAYOUT flag so that every
586 actor using a ClutterFixedLayout manager will automatically benefit
589 » Fix the packing order of ClutterBox so that the convention of
590 first-in-first-painted is maintained
592 » Documentation fixes
600 Clutter 1.1.12 (16/02/2010)
601 ===============================================================================

605 » Fix compilation on 64bit platforms
607 » Fix some races of the Stage resizing on X11
609 » Documentation fixes for Cogl: the coverage is now 100%
611 » Fix rounding errors in the preferred height of the ClutterText
614 » Remove redundant type checks in clutter_actor_get_paint_opacity()
616 » Add support for the GLX_INTEL_swap_event extension; when using this
617 extension on GLX the glXSwapBuffers() call becomes non-blocking and
618 Clutter will use an event to control the master clock.
620 » Improve consistency between ClutterBox and ClutterGroup.
622 » On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
623 Stage X window if the window was not created by Clutter itself
625 » Improve caching of GL constant values
627 » Optimize creating sub-textures of sub-textures
629 » Various fixes for the atlas and the journal
631 » Disable the atlas if FBOs are not supported
641 Clutter 1.1.10 (09/02/2010)
642 ===============================================================================
644 • List of changes since Clutter 1.1.8
646 » Fixed a regression in textures that caused all the textures to be
647 drawn as white rectangles.
649 » Fixed compilation with the Sun C compiler.
651 » Use SSE2 instructions to premultiply RGBA images, if available.
653 » Improve readability of ClutterActor::raise/::lower warnings.
660 Clutter 1.1.8 (08/02/2010)
661 ===============================================================================
663 • List of changes since Clutter 1.1.6
665 » Added ClutterAnimator, a class that allows defining complex
666 implicit animations involving multiple actors and states; this
667 class is mostly meant to be used through the ClutterScript
668 definition format, but it provides a convenience C API for
669 easily building animations.
671 » New experimental COGL API to expose "hardware" buffers such as PBOs or
672 drm surfaces. This API can be used, for instance, to make texture
675 » Fixed the issues with resizable stages getting a 1x1 window with
678 » Expose input devices for every event; by default, X11 and Windows
679 backends expose the core devices only.
681 » Add the ClutterStage:key-focus property, for key focus tracking.
683 » Allow setting transformable value types in ClutterAnimation when
684 calling clutter_animation_bind() and clutter_animation_update().
686 » Delay the creation of the default Stage until clutter_stage_get_default()
687 is actually called; this reduces the work of clutter_init().
689 » Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
691 » Improve the extendability of CoglTexture with internal backends.
693 » Add implicit texture atlasing; Cogl will try to put every texture
694 inside the same texture atlas by default, to avoid state changes
695 in the driver and (hopefully) improve performance.
697 » Fix notification of the cursor and selection changes in ClutterText;
698 this improves the usage of Clutter from A11Y toolkits.
700 » Do not wait for a frame if the system clock goes backwards.
702 » Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
704 » Documentation and build fixes.
717 Clutter 1.1.6 (18/01/2010)
718 ===============================================================================
720 • List of changes since Clutter 1.1.4
722 » Some fixes for the Win32 backend (bug #1905).
724 » Profiling support via the UProf library. Configure with
725 --enable-profile to get a report after each Clutter application is
728 » Improved conformance tests with coverage reports via gcov.
730 » ClutterTexture no longer tries to read back texture data into
731 g_malloc'd memory on unrealize (bug #1842).
733 » The CGL_• defines from cogl-defines.h have been removed. These
734 should not have been used by any applications, but if they were
735 being used then please replace them either with the Cogl enums or
736 with the appropriate GL_• enum if you are using GL directly.
738 » Added a delete-event signal to the stage.
740 » Fix for using cogl_rectangle with different texture coordinates
741 for multiple layers (bug #1937).
743 » Fix for using stencil and depth buffers in FBOs on Intel drivers
746 » Support for subtitles in ClutterMedia.
748 » ClutterGLX will now use an RGB visual by default. For
749 applications (and toolkit integration libraries) that want to
750 enable the ClutterStage:use-alpha property there is a new
751 function: clutter_x11_set_use_argb_visual().
753 » Fix ClutterText to allow using Pango markup and attributes in
754 the same actor (bug #1940).
766 Clutter 1.1.4 (03/01/2010)
767 ===============================================================================
769 • List of changes since Clutter 1.1.2
771 » Update the ClutterScript parser to be more resilient, and support
772 constructor and ChildMeta properties. The parser also respects the
773 order of the properties in the UI definitions when applying them,
774 and will apply the properties of an Actor after building the scene
777 » Simplified the implementation of LayoutManager sub-classes, and added
778 support for animating a layout manager.
780 » Allow short-circuiting some layout operations by setting a specific
781 flag on ClutterActor.
783 » Improve caching of the preferred size of a ClutterActor.
785 » Allow declaring "internal children" for a ClutterContainer
786 implementation: the memory management of these actors will be deferred
787 entirely to the Container.
789 » Let the ClutterStage honour the :opacity property and the alpha component
790 of the stage color. This requires support in the Clutter backend used.
792 » Improve Windows and OSX backends.
794 » Simplify the feature detection code for OpenGL; this also reduced the
795 required OpenGL version to 1.2.
797 » Improve the matrix stack handling code. The matrices can be debugged by
798 using the COGL_DEBUG environment variable, assuming that Clutter was
799 compiled with the right configure-time switch.
801 » Improve COGL API for draw buffers, and for offscreen buffer support.
803 » Add support for text direction to ClutterActor.
805 » Documentation, introspection and build fixes.
822 Clutter 1.1.2 (23/10/2009)
823 ===============================================================================
825 • List of changes since Clutter 1.0
827 » Add ClutterLayoutManager, an abstract proxy class for easily
828 writing layout management policies; also add ClutterLayoutMeta,
829 a class for storing layout properties.
831 » Add ClutterBox, a generic container actor that relies on a
832 ClutterLayoutManager instance to manage the layout of its
835 » Add the following layout managers:
837 - ClutterFixedLayout - a layout manager implementing the
838 policy used by ClutterGroup
840 - ClutterBinLayout - a layout manager for packing actors
841 as layers inside the same area, with per-actor alignment
843 - ClutterFlowLayout - a layout manager arranging actors as
846 - ClutterBoxLayout - a layout manager arranging actors as
849 » Remove the requirement for the backend-specific implementation
850 of ClutterStage to be a ClutterActor: a Stage implementation must
851 only implement the ClutterStageWindow interface. This cleans up
854 » COGL source tree clean up and rationalization; COGL now
855 knows the platform, and not only the driver (GL or GLES) so
856 we can migrate part of the low-level backend code from Clutter
857 to COGL where it makes sense.
859 » Remove code duplication across whole COGL.
861 » The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
862 have been fixed and confirmed working.
864 » Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
865 dumps the contents of each pick() buffer into a PNG file, for
868 » Allow interpolating intervals of ClutterUnits for animating
869 unit-based properties.
871 » Increase strictness and correctness of the ClutterUnits
874 » Add GValue transformation functions for ClutterPath to and
877 » Fix word movement in ClutterText; implement GObject getter for
878 :use-markup; emit notification for :position; decouple the
879 :text property from the :use-markup property.
881 » Do not queue redraws or relayouts on actors currently being
884 » Support #rrggbb and #rgb notations for ClutterColor.
886 » Multiple bug fixes.
888 » Provide _NET_WM_PID on the X11 stage implementation.
890 » Documentation and Introspection annotation fixes.
892 » Add test units for the ClutterActor size requesition.
896 » Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
897 back to Shave on older Automake versions.
917 Clutter 1.0.0 (28/07/2009)
918 ===============================================================================
920 • List of changes since 0.9.8
922 » Allow per-stage disabling of motion event throttling; this should allow
923 platforms or applications that require all the motion events not for
924 drawing purposes to get them exactly like Clutter gets them from the
927 » Various documentation fixes.
929 » Add per-word key navigation inside ClutterText.
931 » Fix the RGB<->HLS conversion.
933 » Various fixes for the OSX backend.
935 » Various build-related fixes.
943 Clutter 0.9.8 (17/07/2009)
944 ===============================================================================
946 • List of changes since 0.9.6
948 » Add more introspection annotations for language bindings.
950 » Fix a bug in clutter_animation_set_alpha(), which also broke the
951 clutter_actor_animate_with_alpha() function.
953 » Check if the stage requires a relayout before showing it; this fixes
954 a bug in the X11-based backends, especially under compositing window
955 managers, where a 640x480 window would flicker before the default
956 stage was shown for the first time.
958 » Performance fixes for Cogl.
960 » Sliced textures were broken by the COGL journalling.
962 » Use the redraw cycle when asynchronously loading textures from
965 » Miscellaneous compilation fixes for the OS X and Windows backends.
967 » Allow querying from within the paint function of an Actor whether
968 the actor is currently being directly painted or by a Clone actor.
970 » In the GLX backend, when using the non-implicit sync-to-vblank inside
971 glXSwapBuffers(), call glFinish() to avoid potential tearing.
981 Clutter 0.9.6 (01/07/2009)
982 ===============================================================================
984 • List of changes since 0.9.4:
986 » Allow the manipulation of the actor's transformation matrix, so that is
987 is possible to apply additional transformations in a way that is
988 compatible with the transformations already applied by the scene graph.
990 » Fix a race in the X11 backend that happened between resizing the stage
991 drawable and the call to glViewport().
993 » Merge the cogl-journal-batching branch; this branch implements batching
994 the geometry of the elements of the scene graph before sending it to
995 OpenGL, thus minimizing the number of state changes and improving the
996 overall performance of Clutter-based applications.
998 » Add more debugging states for Clutter and COGL, which allow the developer
999 to track the state of the journal; to check the VBO fallback paths; to
1000 disable picking for reliable profiling; to disable software-side matrix
1001 transformations in favour of the driver/GPU ones.
1003 » Improve the ability to "break out" of COGL by using gl_begin/gl_end
1004 semantics; applications that drop into raw GL are, though, ignoring all
1005 the caching performed by COGL and might incur in performance issues.
1007 » Fixed the :load-async and :load-data-async properties of Texture by
1008 removing the unneeded G_PARAM_CONSTRUCT flag.
1010 » Added an initial migration guide that shows the porting process from
1011 older releases of Clutter to the 1.0 API; the first chapter deals with
1012 the migration from ClutterEffect to the new implicit animations API.
1014 » Fixed MT-safety for the master clock.
1018 Ole André Vadla Ravnås
1021 Clutter 0.9.4 (19/06/2009)
1022 ===============================================================================
1024 • List of changes since 0.9.2:
1026 » Set the layout height in ClutterText, so that wrapping and ellipsization
1027 work correctly to fill all the allocated area.
1029 » Remove all the units-based API, and migrate all the positional and
1030 dimensional accessors to use floating point values when dealing with
1031 pixels. All the properties dealing with pixels now that a floating
1032 point value as well.
1034 » Add the ability to track wether an actor is going to be painted or not,
1035 using the "mapped" flag. This also allows Clutter to be more strict
1036 in the handling of the scenegraph, ensuring correctness and avoiding
1037 wasting resources on nodes that won't be painted.
1039 » Add debugging facilities for COGL, similar to those of Clutter; through
1040 them is also possible to have an on screen debugging mode that shows the
1041 boundaries of each rectangle sent to the GPU.
1043 » Rework "units" into real logical distance units that can be converted
1044 between millimeters, typographic points and ems into pixels.
1046 » Simplify the Animation class to avoid redundancy and the possibility
1047 of it going out of sync with the Timeline and Alpha instances it uses.
1049 » Move every operation into a single "master clock" source that advances
1050 the timelines, dispatches events and redraws the stages in a predictable
1051 sequence, thus avoiding unneeded redraws. The default is to follow the
1052 sync-to-vblank cycle, if it is supported by the drivers.
1054 » Cache the glyphs geometry into a vertex buffer object to avoid
1055 resubmitting too much information to the GPU.
1057 » Rework the behaviour of ClutterModel when a filter is applied.
1059 » Allow submitting premultiplied texture data; this removes the need
1060 for unpremultiplying data in CairoTexture.
1062 » Add a simple API for submitting blending and texture combining modes
1063 through a string description.
1065 » Move Timelines to pure time-based objects.
1067 » Lots of performance improvements.
1069 » Removal of all the deprecated API.
1071 » Removal of all the fixed point entry points.
1073 » Lots of documentation fixes - the coverage is now 99% of the exported
1074 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
1076 » Generate the GObject Introspection data for both Clutter and COGL
1079 » Build environment fixes.

1358 Clutter 0.9.0 (30/01/2009)
1359 ===============================================================================
1361 • List of changes between 0.8.6 and 0.9.0
1363 » ClutterText is a new actor allowing text display, text editing
1364 both in multi-line and single-line modes, and text selection using
1365 the pointer devices and the keyboard. ClutterText supercedes both
1366 ClutterLabel and ClutterEntry.
1367 » ClutterClone is a new actor that allows cloning of other actors,
1368 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
1369 » ClutterBindingPool is a new API that allows to easily add key bindings
1371 » ClutterAnimation is a new API for implicit animations, similar to
1372 the tweening API used in toolkits like jQuery, Tween and Flash. This
1373 new API supercedes the ClutterEffect API.
1374 » ClutterAlpha uses "animation modes" instead of raw function
1375 pointers; it is still possible to pass alpha functions. The alpha
1376 functions provided by Clutter have been removed from the public
1377 API. It is possible to register global alpha functions and use
1378 them though a logical id.
1379 » The interval of the ClutterAlpha:alpha property has been changed
1380 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
1381 the addition of "overshooting" easing modes.
1382 » COGL now supports backface culling.
1383 » The COGL-based Pango renderer is public API and it is accessible
1384 to developers. It is also possible to access the PangoContext used
1385 by Clutter in order to create PangoLayouts to render text.
1386 » The ClutterFixed API has been moved to COGL.
1387 » COGL does not depend on Clutter data types anymore.
1388 » The ClutterMedia interface has been overhauled: implementations
1389 now must only override the interface properties. The ranges of
1390 some properties have been changed to normalized values.
1391 » COGL now exposes only floating point entry points, and reserves
1392 the eventual conversion to fixed point only when needed. The
1393 fixed point type and macros are publicly available for developers
1394 concerned about floating point operations.
1395 » COGL has a new Vertex Attribues API that allows submitting an
1396 extensible number of vertex attributes to OpenGL in a way that
1397 does not require format conversions and allows fast re-use.
1398 » COGL has a new Material API that decouples paths from fills; it
1399 is possible to create an arbitrary path and fill it with a COGL
1400 texture. The Material API also allows setting multiple texture
1401 layers and defining the blend modes and colors.
1402 » ClutterTexture has the ability to use a worker thread to asynchronously
1403 load an image from a file, as long as the GLib threading support has
1404 been enabled prior to calling clutter_init().
1405 » Clutter now supports localization of the help output, and it
1406 also supports globally setting the text direction for non left to
1408 » ClutterCairoTexture is a new actor that allows using Cairo
1409 to draw on a ClutterTexture; since Cairo does not have an OpenGL
1410 backend, the drawing is not hardware accelerated.
1411 » Clutter has a unit testing suite, based on the GLib unit test
1412 framework, which can be used to track regressions.
1413 » A ClutterPath object has been added, and it is used by the
1414 BehaviourPath. The Path object allows defining paths using a set
1415 of coordinates and operations. A Path can be "painted" either using
1416 COGL primitives or using Cairo primitives, allowing an easier way
1417 to paint non-rectangular shaped actors.
1418 » ClutterInterval is a simple object, used by ClutterAnimation, that
1419 describes an interval between two values, and interpolates between
1420 the initial and final values of the interval.

1656 ===============================================================================
1658 • List of changes between 0.7.0 and 0.7.2
1660 » ClutterTexture has a new :keep-aspect-ratio property; when it is set
1661 to TRUE the texture will return a preferred width maintaining the
1662 aspect ratio with the given height and a preferred height maintaining
1663 the aspect ratio with the given width. This allows to set the width or
1664 the height and have the texture automatically request the height or the
1665 width respectively while maintaining the aspect ratio of the original
1668 » Added XINPUT support on the X11 backends; this provides an initial
1669 support for multiple input devices. The API is X11-specific, and
1670 provides support for querying at run-time support for XINPUT, for
1671 getting a list of input devices and for getting the type of each
1674 » The 'fruity' backend also features multiple device support.

1692 Clutter 0.7.0 (13/06/2008), "Booska"
1693 ===============================================================================
1695 • List of changes between 0.6 and 0.7.0
1697 » COGL, the underlying GL abstraction layer in Clutter, has been
1698 completely rewritten from the ground up. Its no longer a conceptual
1699 hack but a documented, fully featured library pretty much in its
1700 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
1701 OpenGL ES 2.0, providing a smart uniform API over these libraries
1702 with various utility features such as texture tiling abstractions,
1703 paths and primitive rendering, FBO, shaders, etc.
1705 » Clutter now provides an experimental backend for the Apple(tm)
1706 iPhone and iPod Touch families of products.
1708 » The Windows platform is now natively supported instead of
1709 relying on the SDL libraries. The win32 backend is still
1712 » The X11 based backends now feature support for Actors that wrap
1713 external X drawables (i.e the texture-from-pixmap extension and
1716 » Clutter now seamlessly supports multiple stages on the backends
1717 that allow this feature.
1719 » The custom Pango renderer has been completely rewritten, now using
1720 the more modern and maintained PangoCairo (instead of FT2), and avoids
1721 nasty subclassing hacks, supports smooth fast scaling of text, has
1722 many edge case issues fixed and it still is very efficient (using
1723 a texture glyph cache). It is even a little bit faster.
1725 » Better texture support, timeline improvements, ClutterLabel and
1726 ClutterEntry improvements, and container child properties are among
1727 the new features - too many to fit in the NEWS file.
1731 » #358 - "window resizing doesn't show scaled stage"

1827 » Reverted a last minute change in the depth sorting function of
1830 » Added the clutter_actor_move_anchor_point() family of functions,
1831 which will set the anchor point at the given coordinates while
1832 adjusting the actor postion so that the relative position of the
1833 actor toward its parent remains the same.
1835 » Provide a fallback for finding the Clutter alpha functions inside
1836 a UI definition for ClutterScript in case g_module_open() fails.
1838 » Add initial Frame Buffer Objects support in ClutterTexture; using
1839 FBOs, where supported by the hardware and drivers, it's possible to
1840 create a ClutterTexture from any actor.

1872 Clutter 0.5.4 (25/01/2008)
1873 ==========================
1875 • List of changes between 0.5.2 and 0.5.4
1877 » A clutter-x11-<major>.<minor> pkg-config file is installed along
1878 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
1879 ones, for libraries and applications depending on the X11-based
1880 backends (GLX and EGLX).
1882 » Textures are correctly unrealized before changing and freeing the
1885 » It is now possible to block the automatic call to clutter_main_quit()
1886 when closing the stage window using the frame controls by connecting
1887 an handler for the ::event signal on the Clutter stage and checking
1888 for the CLUTTER_DELETE event type and returning TRUE. This allows
1889 the usage of other main loops with GLib reactors (like Python's twisted)
1890 with Clutter without triggering assertions by closing the stage window.
1892 • List of bugs fixed
1894 » #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]

1909 API change [Josh Stewart]
1911 Clutter 0.5.2 (14/01/2008)
1912 ==========================
1914 • List of changes between 0.5.0 and 0.5.2
1916 » ClutterModelDefault has been renamed to ClutterListModel
1918 » ClutterModel now has vector-based variants for append, prepend and
1919 insert methods; these methods are useful for bindings

1926 » #700 - Fix for clutter_effect_rotate() [Neil Roberts]
1928 Clutter 0.5.0 (02/01/2008)
1929 ==========================
1931 • List of changes between 0.4.2 and 0.5.0
1933 » New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
1934 flag set will receive events from the underlying backend; the event
1935 propagation chain will be walked in two directions (from the actor to
1936 the top-level container and back) with the ability to block it in
1939 » ClutterShader, an abstraction over the programmable OpenGL pipeline.
1941 » ClutterScore, an object for controlling timelines; using a score
1942 instance is possible to start multiple timelines at once, or start
1943 a timeline after another has emitted the ::complete signal.
1945 » ClutterScript, an object for parsing a scene from an external file or
1946 a buffer; the scene is described using JSON (JavaScript Object Notation):
1947 every object is defined using its class and properties, and container
1948 objects can have their children defined as well. It is also possible
1949 do describe top-level objects such as timelines and behaviours, and to
1950 automatically connect signal handlers to signal names.
1952 » ClutterTimelines duration can now be set in milliseconds using the
1953 :duration property; the default framerate will be used to compute the
1954 actual duration in frames. The default framerate will be set by the
1955 backend, and can be overridden by the application.
1957 » ClutterTimelines direction can now be set using the :direction
1958 property; a timeline can be set to proceed forward or backward,
1959 and the direction can also be change while the timeline is still
1962 » New, experimental OSX backend.
1964 » Build environment for MS VisualStudio 2005.
1966 » ClutterModel, a generic list-based model object that can be used to
1967 implement actors following the Model-Viewer-Controller design pattern.
1968 Clutter provides a default implementation of ClutterModel, called
1969 ClutterModelDefault and using the GSequence data structure from GLib
1970 to optimize insertion and look up.
1972 » Add the ability to grab pointer and keyboard events: if an actor
1973 is set to have a grab it'll be the only one receiving events until
1974 it releases the grab.
1976 » Add the ability for an actor to receive the key focus; an actor
1977 with key focus will always receive the key events, even if it did
1978 not acquire the keyboard grab.
1980 » It is now possible to set the GL "fog" (also known as "depth cueing")
1981 effect on the ClutterStage; if the fog is enabled, actors farther
1982 away from the view point will fade into the stage background color.
1984 » Each actor now has an "anchor point", a point defined in the actor's
1985 coordinate space that will be used as the origin when scaling and
1986 rotation transformations.
1988 » Every pixel-based API has been doubled with a corresponding
1989 ClutterUnits-based function (postfixed with a '-u'), for instance:
1991 clutter_actor_set_position() - clutter_actor_set_positionu()
1992 clutter_actor_set_size() - clutter_actor_set_sizeu()
1993 clutter_actor_set_depth() - clutter_actor_set_depthu()
1995 This allows sub-pixel precision and device independence.
1997 » The ClutterLabel actor now tries very hard to provide a sane
1998 default size, if no bounding box has been requested; this fixes
1999 the :alignment property and allows the addition of the :justify
2002 » The SDL backend can now be compiled under win32 with MingW; this
2003 backend is still marked as experimental.
2005 » The OSX backend allows the compilation of Clutter under OS X; this
2006 backend is experimental.

2104 has a padding. Margins and paddings are expressed in ClutterUnits,
2105 to ease the transition to the device independent units. You can use

2154 Clutter 0.3 (29/06/2007)
2155 ========================
2157 • List of changes between 0.2.3 and 0.3
2158 » Clutter now supports both switchable windowing system and GL backends.
2159 Window systems supported include GLX, EGL and SDL.
2161 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
2162 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
2163 yet documented - usage external to Clutter is not yet advised.
2165 Backends may provide specific command line options.
2171 The GLX backend is built by default and is currently the most
2172 developed, supported and featured windowing system backend. Only
2173 OpenGL is supported via GLX.
2177 Clutter has experimental support for using SDL. Open GL is supported as
2178 is OpenGL ES via Dogles (very experimental).
2182 Clutter has experimental support for using EGL. Only Open GL ES
2183 is supported by EGL.
2185 EGL support assumes an EGL implementation running atop X Windows.
2190 Clutter now has experimental support for Open GL ES.
2191 Current known issues;
2193 + Unrealising a ClutterTexture will not move pixel data from video
2194 into system memory but simply destroy it.
2195 + BGRA, YUV Texture data not currently supported.
2197 (Use the clutter_feature API to probe for above at runtime)
2199 Open Source ES implementations this has been tested against
2200 include `Vincent' and `dgles'. Support for commerical
2201 implementations may require modifications to the configure.ac
2204 vincent: http://ogl-es.sourceforge.net/
2205 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
2207 dgles: http://developer.hybrid.fi/dgles/index.html
2209 » New ClutterEffect class provides a simplified (and thus less flexible)
2210 API wrapping around behaviours, alphas and timelines.
2211 » New Behaviours - bspline, ellipsis, rotation.
2212 » New built in Alpha functions;
2213 CLUTTER_ALPHA_SINE_INC
2214 CLUTTER_ALPHA_SINE_DEC
2215 CLUTTER_ALPHA_SINE_HALF
2216 CLUTTER_ALPHA_SQUARE
2217 CLUTTER_ALPHA_SMOOTHSTEP_INC
2218 CLUTTER_ALPHA_SMOOTHSTEP_DEC
2219 CLUTTER_ALPHA_EXP_INC
2220 CLUTTER_ALPHA_EXP_DEC
2221 » New Actors and interfaces
2222 + ClutterLayout, for writing extended layout support in actors
2223 + ClutterContainer, for generic container actors
2224 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
2225 + ClutterEntry, text entry actor
2226 » ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
2227 » All internal math now fixed point based.
2228 » Clutter now has it own internal event queue.
2229 » ClutterStage new features;
2230 + Title property for naming in window decorations.
2231 + Perspective setting - The stages perspective can now be modified.
2232 » New Clutter_actor •project API calls allow for querying of tranformed
2233 actor vertices and points.
2234 » New Clutter Feature checks.
2235 » Initial ClutterUnit implementation for device independant positioning.
2236 • List of Bugs fixed
2237 » Various issues with very poor performance and Intel drivers.
2238 » #138 Fix typo in x rotation transform.
2240 Clutter 0.2.3 (2007-04-11)

2269 Clutter 0.2 (18-01-2007)
2270 ========================
2272 • List of changes between 0.2 and 0.1
2273 » Bindings, GStreamer and GTK+ dependencies moved out of tree:
2274 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
2275 » Actors now have an initial floating reference; this means you
2276 don't have to explicitely unref them: every memory an actor
2277 allocates will be freed when the group containing the actor will
2279 » Add basic run-time detection of GL features.
2280 + Use GL_TEXTURE_RECTANGLE_ARB if available.
2281 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
2282 » Add API for behaviours. A ClutterBehaviour is an object which
2283 drives a set of actors using one or more properties depending
2284 on the value of an "alpha" function.
2285 + Provide simple behaviours: ClutterBehaviourOpacity,
2286 ClutterBehaviourPath and ClutterBehaviourScale.
2287 + Provide simple alpha functions for ramps and sine waveforms.
2288 » Add fixed point API for embedded platforms with no FPU.
2289 » Add support for command line switches to Clutter, like debug
2290 flags and abort on warnings; also allow application to hook up
2291 into the initialisation sequence to add their own command line
2293 » Add Pango GL renderer for Clutter, and use it to render text
2294 inside the ClutterLabel actor; this decrease texture memory
2296 » Redo Clutter Label widget, using the new Pango renderer.
2297 » Clutter Textures do not store local pixbuf copy (of texture).
2298 » Redo group and actor scale/sizing API and functionality.
2299 » Add memory management API for ClutterColor, and string parsing.
