163 ===============================================================================
165 * List of changes between 0.7.0 and 0.7.2
167 o ClutterTexture has a new :keep-aspect-ratio property; when it is set
168 to TRUE the texture will return a preferred width maintaining the
169 aspect ratio with the given height and a preferred height maintaining
170 the aspect ratio with the given width. This allows to set the width or
171 the height and have the texture automatically request the height or the
172 width respectively while maintaining the aspect ratio of the original
175 o Added XINPUT support on the X11 backends; this provides an initial
176 support for multiple input devices. The API is X11-specific, and
177 provides support for querying at run-time support for XINPUT, for
178 getting a list of input devices and for getting the type of each
181 o The 'fruity' backend also features multiple device support.

199 Clutter 0.7.0 (13/06/2008), "Booska"
200 ===============================================================================
202 * List of changes between 0.6 and 0.7.0
204 o COGL, the underlying GL abstraction layer in Clutter, has been
205 completely rewritten from the ground up. Its no longer a conceptual
206 hack but a documented, fully featured library pretty much in its
207 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
208 OpenGL ES 2.0, providing a smart uniform API over these libraries
209 with various utility features such as texture tiling abstractions,
210 paths and primitive rendering, FBO, shaders, etc.
212 o Clutter now provides an experimental backend for the Apple(tm)
213 iPhone and iPod Touch families of products.
215 o The Windows platform is now natively supported instead of
216 relying on the SDL libraries. The win32 backend is still
219 o The X11 based backends now feature support for Actors that wrap
220 external X drawables (i.e the texture-from-pixmap extension and
223 o Clutter now seamlessly supports multiple stages on the backends
224 that allow this feature.
226 o The custom Pango renderer has been completely rewritten, now using
227 the more modern and maintained PangoCairo (instead of FT2), and avoids
228 nasty subclassing hacks, supports smooth fast scaling of text, has
229 many edge case issues fixed and it still is very efficient (using
230 a texture glyph cache). It is even a little bit faster.
232 o Better texture support, timeline improvements, ClutterLabel and
233 ClutterEntry improvements, and container child properties are among
234 the new features - too many to fit in the NEWS file.
238 o #358 - "window resizing doesn't show scaled stage"
239 o #425 - "COGL enhancements"

315 o New documentation sections inside the API reference, describing
316 the animation framework.
318 o New API in ClutterActor for computing the actor's vertices in
319 the plane of a given ancestor and accessors to query whether an
320 actor is scaled or rotated
324 o #613 - Extend point transformation API
325 o #779 - Rounding error in ClutterBehaviourScale [Havoc Pennington]
326 o #787 - tiled textures are broken
327 o #796 - segmentation fault when setting label text
329 Clutter 0.5.6 (11/02/2008)
330 ==========================
332 * List of changes between 0.5.4 and 0.5.6
334 o Reverted a last minute change in the depth sorting function of
337 o Added the clutter_actor_move_anchor_point() family of functions,
338 which will set the anchor point at the given coordinates while
339 adjusting the actor postion so that the relative position of the
340 actor toward its parent remains the same.
342 o Provide a fallback for finding the Clutter alpha functions inside
343 a UI definition for ClutterScript in case g_module_open() fails.
345 o Add initial Frame Buffer Objects support in ClutterTexture; using
346 FBOs, where supported by the hardware and drivers, it's possible to
347 create a ClutterTexture from any actor.
351 o #386 - Stage is white unless a timeline is present
352 o #439 - timing related pong lockup due to timeline rewind...
353 o #440 - 1 pixel line flickering
354 o #442 - Shader support
355 o #451 - Improve font rendering quality (Pango)
356 o #452 - Textures are shown with distortion on Solaris/SPARC
358 o #533 - Clutter stage is not shown under some conditions
359 o #540 - ClutterStage isn't always respecting requests to change size
360 o #549 - Backend offscreen API is broken
361 o #613 - Extend point transformation API
362 o #635 - Fix buffer overflow in clutter_texture_get_pixbuf() [Gwenole
364 o #643 - Superfluous "filter-quality" setting in texture_upload_data()?
366 o #689 - Rotating actor through layers does not handle opacity
367 correctly [Josh Stewart]
368 o #710 - Make "box-blur" test shader work in some way [Gwenole Beauchesne]

379 Clutter 0.5.4 (25/01/2008)
380 ==========================
382 * List of changes between 0.5.2 and 0.5.4
384 o A clutter-x11-<major>.<minor> pkg-config file is installed along
385 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
386 ones, for libraries and applications depending on the X11-based
387 backends (GLX and EGLX).
389 o Textures are correctly unrealized before changing and freeing the
392 o It is now possible to block the automatic call to clutter_main_quit()
393 when closing the stage window using the frame controls by connecting
394 an handler for the ::event signal on the Clutter stage and checking
395 for the CLUTTER_DELETE event type and returning TRUE. This allows
396 the usage of other main loops with GLib reactors (like Python's twisted)
397 with Clutter without triggering assertions by closing the stage window.
401 o #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]
402 o #614 - ClutterActor API inconsistencies
403 o #640 - ClutterTexture unrealized with no GL context
404 o #654 - Under heavy load clutter sometimes drops the last frame of
405 a timeline [Johan Bilien]
406 o #672 - Event handling in osx backend is broken [Tommi Komulainen]
407 o #684 - Improve test-scale by also using anchor point [Jaap A. Haitsma]

412 o #714 - clutter_event_copy for enter/leave event generates
413 extra unref [Neil Roberts]
414 o #715 - Type errors in test-shader
415 o #720 - BehaviourScale not working in python after recent
416 API change [Josh Stewart]
418 Clutter 0.5.2 (14/01/2008)
419 ==========================
421 * List of changes between 0.5.0 and 0.5.2
423 o ClutterModelDefault has been renamed to ClutterListModel
425 o ClutterModel now has vector-based variants for append, prepend and
426 insert methods; these methods are useful for bindings
428 o Add units-based variant for clutter_actor_move_by()
432 o #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
433 o #700 - Fix for clutter_effect_rotate() [Neil Roberts]
435 Clutter 0.5.0 (02/01/2008)
436 ==========================
438 * List of changes between 0.4.2 and 0.5.0
440 o New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
441 flag set will receive events from the underlying backend; the event
442 propagation chain will be walked in two directions (from the actor to
443 the top-level container and back) with the ability to block it in
446 o ClutterShader, an abstraction over the programmable OpenGL pipeline.
448 o ClutterScore, an object for controlling timelines; using a score
449 instance is possible to start multiple timelines at once, or start
450 a timeline after another has emitted the ::complete signal.
452 o ClutterScript, an object for parsing a scene from an external file or
453 a buffer; the scene is described using JSON (JavaScript Object Notation):
454 every object is defined using its class and properties, and container
455 objects can have their children defined as well. It is also possible
456 do describe top-level objects such as timelines and behaviours, and to
457 automatically connect signal handlers to signal names.
459 o ClutterTimelines duration can now be set in milliseconds using the
460 :duration property; the default framerate will be used to compute the
461 actual duration in frames. The default framerate will be set by the
462 backend, and can be overridden by the application.
464 o ClutterTimelines direction can now be set using the :direction
465 property; a timeline can be set to proceed forward or backward,
466 and the direction can also be change while the timeline is still
469 o New, experimental OSX backend.
471 o Build environment for MS VisualStudio 2005.
473 o ClutterModel, a generic list-based model object that can be used to
474 implement actors following the Model-Viewer-Controller design pattern.
475 Clutter provides a default implementation of ClutterModel, called
476 ClutterModelDefault and using the GSequence data structure from GLib
477 to optimize insertion and look up.
479 o Add the ability to grab pointer and keyboard events: if an actor
480 is set to have a grab it'll be the only one receiving events until
481 it releases the grab.
483 o Add the ability for an actor to receive the key focus; an actor
484 with key focus will always receive the key events, even if it did
485 not acquire the keyboard grab.
487 o It is now possible to set the GL "fog" (also known as "depth cueing")
488 effect on the ClutterStage; if the fog is enabled, actors farther
489 away from the view point will fade into the stage background color.
491 o Each actor now has an "anchor point", a point defined in the actor's
492 coordinate space that will be used as the origin when scaling and
493 rotation transformations.
495 o Every pixel-based API has been doubled with a corresponding
496 ClutterUnits-based function (postfixed with a '-u'), for instance:
498 clutter_actor_set_position() - clutter_actor_set_positionu()
499 clutter_actor_set_size() - clutter_actor_set_sizeu()
500 clutter_actor_set_depth() - clutter_actor_set_depthu()
502 This allows sub-pixel precision and device independence.
504 o The ClutterLabel actor now tries very hard to provide a sane
505 default size, if no bounding box has been requested; this fixes
506 the :alignment property and allows the addition of the :justify
509 o The SDL backend can now be compiled under win32 with MingW; this
510 backend is still marked as experimental.
512 o The OSX backend allows the compilation of Clutter under OS X; this
513 backend is experimental.
517 o #423 - All actors should emit events rather than just the stage
518 o #424 - Interface definition files
519 o #443 - ClutterModel implementation
520 o #480 - Uninitialized variable in
521 path_alpha_to_position() [Gwenole Beauchesne]
522 o #511 - clutter_stage_get_actor_at_pos problem
523 o #512 - clutter window moves when stage actor is scaled
524 o #518 - XEMBED not supported in eglx backend

533 o #532 - clutter_actor_set_scale_with_gravityx()
534 precision [Gwenole Beauchesne]
535 o #544 - clutter_color_to_hlsx is broken [Neil Roberts]
536 o #546 - ClutterStageState doesn't make sense
537 o #550 - Wanted: Set Actor's position based on center or other
538 edges/corners of quadrangle
539 o #557 - ClutterScript should support complex properties for third

609 o New ClutterBox API: each box has now a colour and a margin (distance
610 between the inner-border and the children); plus, each packed child
611 has a padding. Margins and paddings are expressed in ClutterUnits,
612 to ease the transition to the device independent units. You can use

631 Clutter 0.3.1 (06/07/2007)
632 ========================
634 * List of changes between 0.3 and 0.3.1
635 o EGL. There are now 2 experimental EGL backends;
636 - 'eglx', the former EGL on X11 implementation (now renamed)
637 - 'eglnative', a new EGL 'native' backend which supporting non
638 X11 EGL implementations (i.e framebuffer).
640 o ClutterGroup now returns correct size when a child is removed.

661 Clutter 0.3 (29/06/2007)
662 ========================
664 * List of changes between 0.2.3 and 0.3
665 o Clutter now supports both switchable windowing system and GL backends.
666 Window systems supported include GLX, EGL and SDL.
668 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
669 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
670 yet documented - usage external to Clutter is not yet advised.
672 Backends may provide specific command line options.
678 The GLX backend is built by default and is currently the most
679 developed, supported and featured windowing system backend. Only
680 OpenGL is supported via GLX.
684 Clutter has experimental support for using SDL. Open GL is supported as
685 is OpenGL ES via Dogles (very experimental).
689 Clutter has experimental support for using EGL. Only Open GL ES
692 EGL support assumes an EGL implementation running atop X Windows.
697 Clutter now has experimental support for Open GL ES.
698 Current known issues;
700 + Unrealising a ClutterTexture will not move pixel data from video
701 into system memory but simply destroy it.
702 + BGRA, YUV Texture data not currently supported.
704 (Use the clutter_feature API to probe for above at runtime)
706 Open Source ES implementations this has been tested against
707 include `Vincent' and `dgles'. Support for commerical
708 implementations may require modifications to the configure.ac
711 vincent: http://ogl-es.sourceforge.net/
712 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
714 dgles: http://developer.hybrid.fi/dgles/index.html
716 o New ClutterEffect class provides a simplified (and thus less flexible)
717 API wrapping around behaviours, alphas and timelines.
718 o New Behaviours - bspline, ellipsis, rotation.
719 o New built in Alpha functions;
720 CLUTTER_ALPHA_SINE_INC
721 CLUTTER_ALPHA_SINE_DEC
722 CLUTTER_ALPHA_SINE_HALF
724 CLUTTER_ALPHA_SMOOTHSTEP_INC
725 CLUTTER_ALPHA_SMOOTHSTEP_DEC
726 CLUTTER_ALPHA_EXP_INC
727 CLUTTER_ALPHA_EXP_DEC
728 o New Actors and interfaces
729 + ClutterLayout, for writing extended layout support in actors
730 + ClutterContainer, for generic container actors
731 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
732 + ClutterEntry, text entry actor
733 o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
734 o All internal math now fixed point based.
735 o Clutter now has it own internal event queue.
736 o ClutterStage new features;
737 + Title property for naming in window decorations.
738 + Perspective setting - The stages perspective can now be modified.
739 o New Clutter_actor *project API calls allow for querying of tranformed
740 actor vertices and points.
741 o New Clutter Feature checks.
742 o Initial ClutterUnit implementation for device independant positioning.
744 o Various issues with very poor performance and Intel drivers.
745 o #138 Fix typo in x rotation transform.
747 Clutter 0.2.3 (2007-04-11)
748 ==========================
750 * List of changed between 0.2.2 and 0.2.3

752 o Implement Gravity for ClutterScaleBehaviour. [Matthew, Rob]
754 Clutter 0.2.2 (2007-03-22)
755 ==========================
757 * List of changed between 0.2.1 and 0.2.2
758 o Addition of basic XEMBED support for clutter stage. [Matthew]
759 o Fixes to clutter_texture_get_pixbuf(). [Matthew]
760 o Export clutter_group_remove_all and add associated fixes. [Matthew]
762 Clutter 0.2.1 (2007-02-07)
763 ==========================
765 * List of changed between 0.2.0 and 0.2.1
766 o Add even faster double to integer (and back) conversion
768 o Fix some errors in the fixed point sine waveform

772 o Add a square waveform function. [Emmanuele]
774 o #215 - macro CLUTTER_MARK() not disabled for non-debug builds
776 Clutter 0.2 (18-01-2007)
777 ========================
779 * List of changes between 0.2 and 0.1
780 o Bindings, GStreamer and GTK+ dependencies moved out of tree:
781 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
782 o Actors now have an initial floating reference; this means you
783 don't have to explicitely unref them: every memory an actor
784 allocates will be freed when the group containing the actor will
786 o Add basic run-time detection of GL features.
787 + Use GL_TEXTURE_RECTANGLE_ARB if available.
788 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
789 o Add API for behaviours. A ClutterBehaviour is an object which
790 drives a set of actors using one or more properties depending
791 on the value of an "alpha" function.
792 + Provide simple behaviours: ClutterBehaviourOpacity,
793 ClutterBehaviourPath and ClutterBehaviourScale.
794 + Provide simple alpha functions for ramps and sine waveforms.
795 o Add fixed point API for embedded platforms with no FPU.
796 o Add support for command line switches to Clutter, like debug
797 flags and abort on warnings; also allow application to hook up
798 into the initialisation sequence to add their own command line
800 o Add Pango GL renderer for Clutter, and use it to render text
801 inside the ClutterLabel actor; this decrease texture memory
803 o Redo Clutter Label widget, using the new Pango renderer.
804 o Clutter Textures do not store local pixbuf copy (of texture).
805 o Redo group and actor scale/sizing API and functionality.
806 o Add memory management API for ClutterColor, and string parsing.
808 o #199 - Little group handling fix?
809 o #198 - Detect NPOT support on more systems
810 o #197 - Tiled textures are broken
811 o #196 - Rebuild the examples when the library changes
812 o #156 - clutter_actor_set_position not using the absolute size
813 o #155 - Don't test for XInitThreads [Bastien Nocera]
814 o #154 - Key presses not working in super-oh example [Bastien Nocera]
815 o #152 - Misc fixes [Bastien Nocera]
816 o #143 - Faulty ref-counting in clutter_group_remove [Frederic Riss]
817 o #141 - Copy-pasto in clutter_media_set_volume [Frederic Riss]
818 o #101 - No package 'x11' found -- wrong configure [Tomasz Torcz]
819 o #98 - Enabling trails in super-oh crashes
