1 Clutter 1.1.12 (16/02/2010)
2 ===============================================================================
4 * List of changes since Clutter 1.1.10
6 o Fix compilation on 64bit platforms
8 o Fix some races of the Stage resizing on X11
10 o Documentation fixes for Cogl: the coverage is now 100%
12 o Fix rounding errors in the preferred height of the ClutterText
15 o Remove redundant type checks in clutter_actor_get_paint_opacity()
17 o Add support for the GLX_INTEL_swap_event extension; when using this
18 extension on GLX the glXSwapBuffers() call becomes non-blocking and
19 Clutter will use an event to control the master clock.
21 o Improve consistency between ClutterBox and ClutterGroup.
23 o On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
24 Stage X window if the window was not created by Clutter itself
26 o Improve caching of GL constant values
28 o Optimize creating sub-textures of sub-textures
30 o Various fixes for the atlas and the journal
32 o Disable the atlas if FBOs are not supported
34 Clutter 1.1.10 (09/02/2010)
35 ===============================================================================
37 * List of changes since Clutter 1.1.8
39 o Fixed a regression in textures that caused all the textures to be
40 drawn as white rectangles.
42 o Fixed compilation with the Sun C compiler.
44 o Use SSE2 instructions to premultiply RGBA images, if available.
46 o Improve readability of ClutterActor::raise/::lower warnings.
53 Clutter 1.1.8 (08/02/2010)
54 ===============================================================================
56 * List of changes since Clutter 1.1.6
58 o Added ClutterAnimator, a class that allows defining complex
59 implicit animations involving multiple actors and states; this
60 class is mostly meant to be used through the ClutterScript
61 definition format, but it provides a convenience C API for
62 easily building animations.
64 o New experimental COGL API to expose "hardware" buffers such as PBOs or
65 drm surfaces. This API can be used, for instance, to make texture
68 o Fixed the issues with resizable stages getting a 1x1 window with
71 o Expose input devices for every event; by default, X11 and Windows
72 backends expose the core devices only.
74 o Add the ClutterStage:key-focus property, for key focus tracking.
76 o Allow setting transformable value types in ClutterAnimation when
77 calling clutter_animation_bind() and clutter_animation_update().
79 o Delay the creation of the default Stage until clutter_stage_get_default()
80 is actually called; this reduces the work of clutter_init().
82 o Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
84 o Improve the extendability of CoglTexture with internal backends.
86 o Add implicit texture atlasing; Cogl will try to put every texture
87 inside the same texture atlas by default, to avoid state changes
88 in the driver and (hopefully) improve performance.
90 o Fix notification of the cursor and selection changes in ClutterText;
91 this improves the usage of Clutter from A11Y toolkits.
93 o Do not wait for a frame if the system clock goes backwards.
95 o Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
97 o Documentation and build fixes.
110 Clutter 1.1.6 (18/01/2010)
111 ===============================================================================
113 * List of changes since Clutter 1.1.4
115 o Some fixes for the Win32 backend (bug #1905).
117 o Profiling support via the UProf library. Configure with
118 --enable-profile to get a report after each Clutter application is
121 o Improved conformance tests with coverage reports via gcov.
123 o ClutterTexture no longer tries to read back texture data into
124 g_malloc'd memory on unrealize (bug #1842).
126 o The CGL_* defines from cogl-defines.h have been removed. These
127 should not have been used by any applications, but if they were
128 being used then please replace them either with the Cogl enums or
129 with the appropriate GL_* enum if you are using GL directly.
131 o Added a delete-event signal to the stage.
133 o Fix for using cogl_rectangle with different texture coordinates
134 for multiple layers (bug #1937).
136 o Fix for using stencil and depth buffers in FBOs on Intel drivers
139 o Support for subtitles in ClutterMedia.
141 o ClutterGLX will now use an RGB visual by default. For
142 applications (and toolkit integration libraries) that want to
143 enable the ClutterStage:use-alpha property there is a new
144 function: clutter_x11_set_use_argb_visual().
146 o Fix ClutterText to allow using Pango markup and attributes in
147 the same actor (bug #1940).
159 Clutter 1.1.4 (03/01/2010)
160 ===============================================================================
162 * List of changes since Clutter 1.1.2
164 o Update the ClutterScript parser to be more resilient, and support
165 constructor and ChildMeta properties. The parser also respects the
166 order of the properties in the UI definitions when applying them,
167 and will apply the properties of an Actor after building the scene
170 o Simplified the implementation of LayoutManager sub-classes, and added
171 support for animating a layout manager.
173 o Allow short-circuiting some layout operations by setting a specific
174 flag on ClutterActor.
176 o Improve caching of the preferred size of a ClutterActor.
178 o Allow declaring "internal children" for a ClutterContainer
179 implementation: the memory management of these actors will be deferred
180 entirely to the Container.
182 o Let the ClutterStage honour the :opacity property and the alpha component
183 of the stage color. This requires support in the Clutter backend used.
185 o Improve Windows and OSX backends.
187 o Simplify the feature detection code for OpenGL; this also reduced the
188 required OpenGL version to 1.2.
190 o Improve the matrix stack handling code. The matrices can be debugged by
191 using the COGL_DEBUG environment variable, assuming that Clutter was
192 compiled with the right configure-time switch.
194 o Improve COGL API for draw buffers, and for offscreen buffer support.
196 o Add support for text direction to ClutterActor.
198 o Documentation, introspection and build fixes.
215 Clutter 1.1.2 (23/10/2009)
216 ===============================================================================
218 * List of changes since Clutter 1.0
220 o Add ClutterLayoutManager, an abstract proxy class for easily
221 writing layout management policies; also add ClutterLayoutMeta,
222 a class for storing layout properties.
224 o Add ClutterBox, a generic container actor that relies on a
225 ClutterLayoutManager instance to manage the layout of its
228 o Add the following layout managers:
230 - ClutterFixedLayout - a layout manager implementing the
231 policy used by ClutterGroup
233 - ClutterBinLayout - a layout manager for packing actors
234 as layers inside the same area, with per-actor alignment
236 - ClutterFlowLayout - a layout manager arranging actors as
239 - ClutterBoxLayout - a layout manager arranging actors as
242 o Remove the requirement for the backend-specific implementation
243 of ClutterStage to be a ClutterActor: a Stage implementation must
244 only implement the ClutterStageWindow interface. This cleans up
247 o COGL source tree clean up and rationalization; COGL now
248 knows the platform, and not only the driver (GL or GLES) so
249 we can migrate part of the low-level backend code from Clutter
250 to COGL where it makes sense.
252 o Remove code duplication across whole COGL.
254 o The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
255 have been fixed and confirmed working.
257 o Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
258 dumps the contents of each pick() buffer into a PNG file, for
261 o Allow interpolating intervals of ClutterUnits for animating
262 unit-based properties.
264 o Increase strictness and correctness of the ClutterUnits
267 o Add GValue transformation functions for ClutterPath to and
270 o Fix word movement in ClutterText; implement GObject getter for
271 :use-markup; emit notification for :position; decouple the
272 :text property from the :use-markup property.
274 o Do not queue redraws or relayouts on actors currently being
277 o Support #rrggbb and #rgb notations for ClutterColor.
279 o Multiple bug fixes.
281 o Provide _NET_WM_PID on the X11 stage implementation.
283 o Documentation and Introspection annotation fixes.
285 o Add test units for the ClutterActor size requesition.
289 o Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
290 back to Shave on older Automake versions.
310 Clutter 1.0.0 (28/07/2009)
311 ===============================================================================
313 * List of changes since 0.9.8
315 o Allow per-stage disabling of motion event throttling; this should allow
316 platforms or applications that require all the motion events not for
317 drawing purposes to get them exactly like Clutter gets them from the
320 o Various documentation fixes.
322 o Add per-word key navigation inside ClutterText.
324 o Fix the RGB<->HLS conversion.
326 o Various fixes for the OSX backend.
328 o Various build-related fixes.
336 Clutter 0.9.8 (17/07/2009)
337 ===============================================================================
339 * List of changes since 0.9.6
341 o Add more introspection annotations for language bindings.
343 o Fix a bug in clutter_animation_set_alpha(), which also broke the
344 clutter_actor_animate_with_alpha() function.
346 o Check if the stage requires a relayout before showing it; this fixes
347 a bug in the X11-based backends, especially under compositing window
348 managers, where a 640x480 window would flicker before the default
349 stage was shown for the first time.
351 o Performance fixes for Cogl.
353 o Sliced textures were broken by the COGL journalling.
355 o Use the redraw cycle when asynchronously loading textures from
358 o Miscellaneous compilation fixes for the OS X and Windows backends.
360 o Allow querying from within the paint function of an Actor whether
361 the actor is currently being directly painted or by a Clone actor.
363 o In the GLX backend, when using the non-implicit sync-to-vblank inside
364 glXSwapBuffers(), call glFinish() to avoid potential tearing.
374 Clutter 0.9.6 (01/07/2009)
375 ===============================================================================
377 * List of changes since 0.9.4:
379 o Allow the manipulation of the actor's transformation matrix, so that is
380 is possible to apply additional transformations in a way that is
381 compatible with the transformations already applied by the scene graph.
383 o Fix a race in the X11 backend that happened between resizing the stage
384 drawable and the call to glViewport().
386 o Merge the cogl-journal-batching branch; this branch implements batching
387 the geometry of the elements of the scene graph before sending it to
388 OpenGL, thus minimizing the number of state changes and improving the
389 overall performance of Clutter-based applications.
391 o Add more debugging states for Clutter and COGL, which allow the developer
392 to track the state of the journal; to check the VBO fallback paths; to
393 disable picking for reliable profiling; to disable software-side matrix
394 transformations in favour of the driver/GPU ones.
396 o Improve the ability to "break out" of COGL by using gl_begin/gl_end
397 semantics; applications that drop into raw GL are, though, ignoring all
398 the caching performed by COGL and might incur in performance issues.
400 o Fixed the :load-async and :load-data-async properties of Texture by
401 removing the unneeded G_PARAM_CONSTRUCT flag.
403 o Added an initial migration guide that shows the porting process from
404 older releases of Clutter to the 1.0 API; the first chapter deals with
405 the migration from ClutterEffect to the new implicit animations API.
407 o Fixed MT-safety for the master clock.
411 Ole André Vadla Ravnås
414 Clutter 0.9.4 (19/06/2009)
415 ===============================================================================
417 * List of changes since 0.9.2:
419 o Set the layout height in ClutterText, so that wrapping and ellipsization
420 work correctly to fill all the allocated area.
422 o Remove all the units-based API, and migrate all the positional and
423 dimensional accessors to use floating point values when dealing with
424 pixels. All the properties dealing with pixels now that a floating
427 o Add the ability to track wether an actor is going to be painted or not,
428 using the "mapped" flag. This also allows Clutter to be more strict
429 in the handling of the scenegraph, ensuring correctness and avoiding
430 wasting resources on nodes that won't be painted.
432 o Add debugging facilities for COGL, similar to those of Clutter; through
433 them is also possible to have an on screen debugging mode that shows the
434 boundaries of each rectangle sent to the GPU.
436 o Rework "units" into real logical distance units that can be converted
437 between millimeters, typographic points and ems into pixels.
439 o Simplify the Animation class to avoid redundancy and the possibility
440 of it going out of sync with the Timeline and Alpha instances it uses.
442 o Move every operation into a single "master clock" source that advances
443 the timelines, dispatches events and redraws the stages in a predictable
444 sequence, thus avoiding unneeded redraws. The default is to follow the
445 sync-to-vblank cycle, if it is supported by the drivers.
447 o Cache the glyphs geometry into a vertex buffer object to avoid
448 resubmitting too much information to the GPU.
450 o Rework the behaviour of ClutterModel when a filter is applied.
452 o Allow submitting premultiplied texture data; this removes the need
453 for unpremultiplying data in CairoTexture.
455 o Add a simple API for submitting blending and texture combining modes
456 through a string description.
458 o Move Timelines to pure time-based objects.
460 o Lots of performance improvements.
462 o Removal of all the deprecated API.
464 o Removal of all the fixed point entry points.
466 o Lots of documentation fixes - the coverage is now 99% of the exported
467 1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
469 o Generate the GObject Introspection data for both Clutter and COGL
472 o Build environment fixes.

751 Clutter 0.9.0 (30/01/2009)
752 ===============================================================================
754 * List of changes between 0.8.6 and 0.9.0
756 o ClutterText is a new actor allowing text display, text editing
757 both in multi-line and single-line modes, and text selection using
758 the pointer devices and the keyboard. ClutterText supercedes both
759 ClutterLabel and ClutterEntry.
760 o ClutterClone is a new actor that allows cloning of other actors,
761 both simple and composite. ClutterClone supercedes ClutterCloneTexture.
762 o ClutterBindingPool is a new API that allows to easily add key bindings
764 o ClutterAnimation is a new API for implicit animations, similar to
765 the tweening API used in toolkits like jQuery, Tween and Flash. This
766 new API supercedes the ClutterEffect API.
767 o ClutterAlpha uses "animation modes" instead of raw function
768 pointers; it is still possible to pass alpha functions. The alpha
769 functions provided by Clutter have been removed from the public
770 API. It is possible to register global alpha functions and use
771 them though a logical id.
772 o The interval of the ClutterAlpha:alpha property has been changed
773 to a floating point value in the [ -1.0, 2.0 ] range; this allowed
774 the addition of "overshooting" easing modes.
775 o COGL now supports backface culling.
776 o The COGL-based Pango renderer is public API and it is accessible
777 to developers. It is also possible to access the PangoContext used
778 by Clutter in order to create PangoLayouts to render text.
779 o The ClutterFixed API has been moved to COGL.
780 o COGL does not depend on Clutter data types anymore.
781 o The ClutterMedia interface has been overhauled: implementations
782 now must only override the interface properties. The ranges of
783 some properties have been changed to normalized values.
784 o COGL now exposes only floating point entry points, and reserves
785 the eventual conversion to fixed point only when needed. The
786 fixed point type and macros are publicly available for developers
787 concerned about floating point operations.
788 o COGL has a new Vertex Attribues API that allows submitting an
789 extensible number of vertex attributes to OpenGL in a way that
790 does not require format conversions and allows fast re-use.
791 o COGL has a new Material API that decouples paths from fills; it
792 is possible to create an arbitrary path and fill it with a COGL
793 texture. The Material API also allows setting multiple texture
794 layers and defining the blend modes and colors.
795 o ClutterTexture has the ability to use a worker thread to asynchronously
796 load an image from a file, as long as the GLib threading support has
797 been enabled prior to calling clutter_init().
798 o Clutter now supports localization of the help output, and it
799 also supports globally setting the text direction for non left to
801 o ClutterCairoTexture is a new actor that allows using Cairo
802 to draw on a ClutterTexture; since Cairo does not have an OpenGL
803 backend, the drawing is not hardware accelerated.
804 o Clutter has a unit testing suite, based on the GLib unit test
805 framework, which can be used to track regressions.
806 o A ClutterPath object has been added, and it is used by the
807 BehaviourPath. The Path object allows defining paths using a set
808 of coordinates and operations. A Path can be "painted" either using
809 COGL primitives or using Cairo primitives, allowing an easier way
810 to paint non-rectangular shaped actors.
811 o ClutterInterval is a simple object, used by ClutterAnimation, that
812 describes an interval between two values, and interpolates between
813 the initial and final values of the interval.

1049 ===============================================================================
1051 * List of changes between 0.7.0 and 0.7.2
1053 o ClutterTexture has a new :keep-aspect-ratio property; when it is set
1054 to TRUE the texture will return a preferred width maintaining the
1055 aspect ratio with the given height and a preferred height maintaining
1056 the aspect ratio with the given width. This allows to set the width or
1057 the height and have the texture automatically request the height or the
1058 width respectively while maintaining the aspect ratio of the original
1061 o Added XINPUT support on the X11 backends; this provides an initial
1062 support for multiple input devices. The API is X11-specific, and
1063 provides support for querying at run-time support for XINPUT, for
1064 getting a list of input devices and for getting the type of each
1067 o The 'fruity' backend also features multiple device support.
1069 * List of bugs fixed
1071 o #816 - clutter_actor_request_coords() should take a const box.
1072 o #836 - Optimize clutter_label_query_coords()

1085 Clutter 0.7.0 (13/06/2008), "Booska"
1086 ===============================================================================
1088 * List of changes between 0.6 and 0.7.0
1090 o COGL, the underlying GL abstraction layer in Clutter, has been
1091 completely rewritten from the ground up. Its no longer a conceptual
1092 hack but a documented, fully featured library pretty much in its
1093 own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
1094 OpenGL ES 2.0, providing a smart uniform API over these libraries
1095 with various utility features such as texture tiling abstractions,
1096 paths and primitive rendering, FBO, shaders, etc.
1098 o Clutter now provides an experimental backend for the Apple(tm)
1099 iPhone and iPod Touch families of products.
1101 o The Windows platform is now natively supported instead of
1102 relying on the SDL libraries. The win32 backend is still
1105 o The X11 based backends now feature support for Actors that wrap
1106 external X drawables (i.e the texture-from-pixmap extension and
1109 o Clutter now seamlessly supports multiple stages on the backends
1110 that allow this feature.
1112 o The custom Pango renderer has been completely rewritten, now using
1113 the more modern and maintained PangoCairo (instead of FT2), and avoids
1114 nasty subclassing hacks, supports smooth fast scaling of text, has
1115 many edge case issues fixed and it still is very efficient (using
1116 a texture glyph cache). It is even a little bit faster.
1118 o Better texture support, timeline improvements, ClutterLabel and
1119 ClutterEntry improvements, and container child properties are among
1120 the new features - too many to fit in the NEWS file.
1124 o #358 - "window resizing doesn't show scaled stage"
1125 o #425 - "COGL enhancements"

1215 Clutter 0.5.6 (11/02/2008)
1216 ==========================
1218 * List of changes between 0.5.4 and 0.5.6
1220 o Reverted a last minute change in the depth sorting function of
1223 o Added the clutter_actor_move_anchor_point() family of functions,
1224 which will set the anchor point at the given coordinates while
1225 adjusting the actor postion so that the relative position of the
1226 actor toward its parent remains the same.
1228 o Provide a fallback for finding the Clutter alpha functions inside
1229 a UI definition for ClutterScript in case g_module_open() fails.
1231 o Add initial Frame Buffer Objects support in ClutterTexture; using
1232 FBOs, where supported by the hardware and drivers, it's possible to
1233 create a ClutterTexture from any actor.
1235 * List of bugs fixed
1237 o #386 - Stage is white unless a timeline is present
1238 o #439 - timing related pong lockup due to timeline rewind...
1239 o #440 - 1 pixel line flickering
1240 o #442 - Shader support
1241 o #451 - Improve font rendering quality (Pango)
1242 o #452 - Textures are shown with distortion on Solaris/SPARC
1243 o #526 - OSX backend
1244 o #533 - Clutter stage is not shown under some conditions
1245 o #540 - ClutterStage isn't always respecting requests to change size
1246 o #549 - Backend offscreen API is broken
1247 o #613 - Extend point transformation API
1248 o #635 - Fix buffer overflow in clutter_texture_get_pixbuf() [Gwenole
1250 o #643 - Superfluous "filter-quality" setting in texture_upload_data()?
1251 [Gwenole Beauchesne]
1252 o #689 - Rotating actor through layers does not handle opacity
1253 correctly [Josh Stewart]
1254 o #710 - Make "box-blur" test shader work in some way [Gwenole Beauchesne]
1255 o #719 - X11 backend does not check window field in events [Havoc

1265 Clutter 0.5.4 (25/01/2008)
1266 ==========================
1268 * List of changes between 0.5.2 and 0.5.4
1270 o A clutter-x11-<major>.<minor> pkg-config file is installed along
1271 with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
1272 ones, for libraries and applications depending on the X11-based
1273 backends (GLX and EGLX).
1275 o Textures are correctly unrealized before changing and freeing the
1278 o It is now possible to block the automatic call to clutter_main_quit()
1279 when closing the stage window using the frame controls by connecting
1280 an handler for the ::event signal on the Clutter stage and checking
1281 for the CLUTTER_DELETE event type and returning TRUE. This allows
1282 the usage of other main loops with GLib reactors (like Python's twisted)
1283 with Clutter without triggering assertions by closing the stage window.
1285 * List of bugs fixed
1287 o #564 - Add more precise clutter_qdivx() [Gwenole Beauchesne]
1288 o #614 - ClutterActor API inconsistencies

1302 API change [Josh Stewart]
1304 Clutter 0.5.2 (14/01/2008)
1305 ==========================
1307 * List of changes between 0.5.0 and 0.5.2
1309 o ClutterModelDefault has been renamed to ClutterListModel
1311 o ClutterModel now has vector-based variants for append, prepend and
1312 insert methods; these methods are useful for bindings
1314 o Add units-based variant for clutter_actor_move_by()
1316 * List of bugs fixed
1318 o #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
1319 o #700 - Fix for clutter_effect_rotate() [Neil Roberts]
1321 Clutter 0.5.0 (02/01/2008)
1322 ==========================
1324 * List of changes between 0.4.2 and 0.5.0
1326 o New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
1327 flag set will receive events from the underlying backend; the event
1328 propagation chain will be walked in two directions (from the actor to
1329 the top-level container and back) with the ability to block it in
1332 o ClutterShader, an abstraction over the programmable OpenGL pipeline.
1334 o ClutterScore, an object for controlling timelines; using a score
1335 instance is possible to start multiple timelines at once, or start
1336 a timeline after another has emitted the ::complete signal.
1338 o ClutterScript, an object for parsing a scene from an external file or
1339 a buffer; the scene is described using JSON (JavaScript Object Notation):
1340 every object is defined using its class and properties, and container
1341 objects can have their children defined as well. It is also possible
1342 do describe top-level objects such as timelines and behaviours, and to
1343 automatically connect signal handlers to signal names.
1345 o ClutterTimelines duration can now be set in milliseconds using the
1346 :duration property; the default framerate will be used to compute the
1347 actual duration in frames. The default framerate will be set by the
1348 backend, and can be overridden by the application.
1350 o ClutterTimelines direction can now be set using the :direction
1351 property; a timeline can be set to proceed forward or backward,
1352 and the direction can also be change while the timeline is still
1355 o New, experimental OSX backend.
1357 o Build environment for MS VisualStudio 2005.
1359 o ClutterModel, a generic list-based model object that can be used to
1360 implement actors following the Model-Viewer-Controller design pattern.
1361 Clutter provides a default implementation of ClutterModel, called
1362 ClutterModelDefault and using the GSequence data structure from GLib
1363 to optimize insertion and look up.
1365 o Add the ability to grab pointer and keyboard events: if an actor
1366 is set to have a grab it'll be the only one receiving events until
1367 it releases the grab.
1369 o Add the ability for an actor to receive the key focus; an actor
1370 with key focus will always receive the key events, even if it did
1371 not acquire the keyboard grab.
1373 o It is now possible to set the GL "fog" (also known as "depth cueing")
1374 effect on the ClutterStage; if the fog is enabled, actors farther
1375 away from the view point will fade into the stage background color.
1377 o Each actor now has an "anchor point", a point defined in the actor's
1378 coordinate space that will be used as the origin when scaling and
1379 rotation transformations.
1381 o Every pixel-based API has been doubled with a corresponding
1382 ClutterUnits-based function (postfixed with a '-u'), for instance:
1384 clutter_actor_set_position() - clutter_actor_set_positionu()
1385 clutter_actor_set_size() - clutter_actor_set_sizeu()
1386 clutter_actor_set_depth() - clutter_actor_set_depthu()
1388 This allows sub-pixel precision and device independence.
1390 o The ClutterLabel actor now tries very hard to provide a sane
1391 default size, if no bounding box has been requested; this fixes
1392 the :alignment property and allows the addition of the :justify
1395 o The SDL backend can now be compiled under win32 with MingW; this
1396 backend is still marked as experimental.
1398 o The OSX backend allows the compilation of Clutter under OS X; this
1399 backend is experimental.

1497 has a padding. Margins and paddings are expressed in ClutterUnits,
1498 to ease the transition to the device independent units. You can use
1499 clutter_box_set_default_padding() if you want the same padding for

1521 o EGL. There are now 2 experimental EGL backends;
1522 - 'eglx', the former EGL on X11 implementation (now renamed)
1523 - 'eglnative', a new EGL 'native' backend which supporting non
1524 X11 EGL implementations (i.e framebuffer).

1548 ========================
1550 * List of changes between 0.2.3 and 0.3
1551 o Clutter now supports both switchable windowing system and GL backends.
1552 Window systems supported include GLX, EGL and SDL.
1554 GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
1555 provided by a small basic abstraction layer 'cogl.h'. Cogl is not
1556 yet documented - usage external to Clutter is not yet advised.
1558 Backends may provide specific command line options.
1564 The GLX backend is built by default and is currently the most
1565 developed, supported and featured windowing system backend. Only
1566 OpenGL is supported via GLX.
1570 Clutter has experimental support for using SDL. Open GL is supported as
1571 is OpenGL ES via Dogles (very experimental).
1575 Clutter has experimental support for using EGL. Only Open GL ES
1576 is supported by EGL.
1578 EGL support assumes an EGL implementation running atop X Windows.
1583 Clutter now has experimental support for Open GL ES.
1584 Current known issues;
1586 + Unrealising a ClutterTexture will not move pixel data from video
1587 into system memory but simply destroy it.
1588 + BGRA, YUV Texture data not currently supported.
1590 (Use the clutter_feature API to probe for above at runtime)
1592 Open Source ES implementations this has been tested against
1593 include `Vincent' and `dgles'. Support for commerical
1594 implementations may require modifications to the configure.ac
1597 vincent: http://ogl-es.sourceforge.net/
1598 (Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
1600 dgles: http://developer.hybrid.fi/dgles/index.html
1602 o New ClutterEffect class provides a simplified (and thus less flexible)
1603 API wrapping around behaviours, alphas and timelines.
1604 o New Behaviours - bspline, ellipsis, rotation.
1605 o New built in Alpha functions;
1606 CLUTTER_ALPHA_SINE_INC

1616 + ClutterContainer, for generic container actors
1617 + ClutterBox, ClutterVBox and ClutterHBox layout actors.
1618 + ClutterEntry, text entry actor
1619 o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
1620 o All internal math now fixed point based.
1621 o Clutter now has it own internal event queue.
1622 o ClutterStage new features;
1623 + Title property for naming in window decorations.
1624 + Perspective setting - The stages perspective can now be modified.
1625 o New Clutter_actor *project API calls allow for querying of tranformed
1626 actor vertices and points.
1627 o New Clutter Feature checks.
1628 o Initial ClutterUnit implementation for device independant positioning.
1629 * List of Bugs fixed
1630 o Various issues with very poor performance and Intel drivers.
1631 o #138 Fix typo in x rotation transform.

1660 o #215 - macro CLUTTER_MARK() not disabled for non-debug builds
1662 Clutter 0.2 (18-01-2007)
1663 ========================
1665 * List of changes between 0.2 and 0.1
1666 o Bindings, GStreamer and GTK+ dependencies moved out of tree:
1667 now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
1668 o Actors now have an initial floating reference; this means you
1669 don't have to explicitely unref them: every memory an actor
1670 allocates will be freed when the group containing the actor will
1672 o Add basic run-time detection of GL features.
1673 + Use GL_TEXTURE_RECTANGLE_ARB if available.
1674 + Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
1675 o Add API for behaviours. A ClutterBehaviour is an object which
1676 drives a set of actors using one or more properties depending
1677 on the value of an "alpha" function.
1678 + Provide simple behaviours: ClutterBehaviourOpacity,
1679 ClutterBehaviourPath and ClutterBehaviourScale.
1680 + Provide simple alpha functions for ramps and sine waveforms.
1681 o Add fixed point API for embedded platforms with no FPU.
1682 o Add support for command line switches to Clutter, like debug
1683 flags and abort on warnings; also allow application to hook up
1684 into the initialisation sequence to add their own command line
1686 o Add Pango GL renderer for Clutter, and use it to render text
1687 inside the ClutterLabel actor; this decrease texture memory
1689 o Redo Clutter Label widget, using the new Pango renderer.
1690 o Clutter Textures do not store local pixbuf copy (of texture).
1691 o Redo group and actor scale/sizing API and functionality.
1692 o Add memory management API for ClutterColor, and string parsing.
1694 o #199 - Little group handling fix?

1712 o Hopefully enough functionality to build things.
1713 o Basic gstreamer 0.10 video playback support.
1714 o Fairly stable API, though in no way totally stable.
1715 Expect CHANGES in future versions.
1716 o Some simple examples ( also see OPT ).
1717 o An experimental GTK-Clutter widget.
1718 o Fairly complete Python bindings.
1719 o Non complete but hopefully useful API documentation.
