Clutter 0.2 ()
Clutter 0.3 ()
========================
* List of changes between 0.2.3 and 0.3
o Clutter now supports both switchable windowing system and GL backends.
Window systems supported include GLX, EGL and SDL.
GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
provided by a small basic abstraction layer 'cogl.h'. Cogl is not
yet documented - usage external to Clutter is not yet advised.
Backends may provide specific command line options.
Notes;
GLX
---
The GLX backend is built by default and is currently the most
developed, supported and featured windowing system backend. Only
OpenGL is supported via GLX.
SDL
---
Clutter has experimental support for using SDL. Open GL is supported as
is OpenGL ES via Dogles (very experimental).
EGL
---
Clutter has experimental support for using EGL. Only Open GL ES
is supported by EGL.
EGL support assumes an EGL implementation running atop X Windows.
Open GL ES.
-----------
Clutter now has experimental support for Open GL ES.
Current known issues;
+ Unrealising a ClutterTexture will not move pixel data from video
into system memory but simply destroy it.
+ BGRA, YUV Texture data not currently supported.
(Use the clutter_feature API to probe for above at runtime)
Open Source ES implementations this has been tested against
include `Vincent' and `dgles'. Support for commerical
implementations may require modifications to the configure.ac
script.
vincent: http://ogl-es.sourceforge.net/
(Also see: http://svn.o-hand.com/repos/misc/trunk/ogles/ )
dgles: http://developer.hybrid.fi/dgles/index.html
o New ClutterEffect class provides a simplified (and thus less flexible)
API wrapping around behaviours, alphas and timelines.
o New Behaviours - bspline, ellipsis, rotation.
o New built in Alpha functions;
CLUTTER_ALPHA_SINE_INC
CLUTTER_ALPHA_SINE_DEC
CLUTTER_ALPHA_SINE_HALF
CLUTTER_ALPHA_SQUARE
CLUTTER_ALPHA_SMOOTHSTEP_INC
CLUTTER_ALPHA_SMOOTHSTEP_DEC
CLUTTER_ALPHA_EXP_INC
CLUTTER_ALPHA_EXP_DEC
o New Actors
+ ClutterContainer and ClutterVBox, ClutterHBox layout actors.
+ ClutterEntry, text entry actor
o ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
o All internal math now fixed point based.
o Clutter now has it own internal event queue.
o ClutterStage new features;
+ Title property for naming in window decorations.
+ Perspective setting - The stages perspective can now be modified.
o New Clutter_actor *project API calls allow for querying of tranformed
actor vertices and points.
o New Clutter Feature checks.
o Initial ClutterUnit implementation for device independant positioning.
* List of Bugs fixed
o Various issues with very poor performance and Intel drivers.
o #138 Fix typo in x rotation transform.
Clutter 0.2.3 (2007-04-11)
==========================
* List of changed between 0.2.2 and 0.2.3
o Fixes to tile based textures and again clutter_texture_get_pixbuf(). [Matthew]
o Implement Gravity for ClutterScaleBehaviour. [Matthew, Rob]
Clutter 0.2.2 (2007-03-22)
==========================
* List of changed between 0.2.1 and 0.2.2
o Addition of basic XEMBED support for clutter stage. [Matthew]
o Fixes to clutter_texture_get_pixbuf(). [Matthew]
o Export clutter_group_remove_all and add associated fixes. [Matthew]
Clutter 0.2.1 (2007-02-07)
==========================
* List of changed between 0.2.0 and 0.2.1
o Add even faster double to integer (and back) conversion
functions. [Tomas]
o Fix some errors in the fixed point sine waveform
function. [Tomas]
o Use fixed point math in the Pango renderer. [Tomas]
o Improve the GL version check. [Matthew]
o Add a square waveform function. [Emmanuele]
* List of bugs fixed
o #215 - macro CLUTTER_MARK() not disabled for non-debug builds
Clutter 0.2 (18-01-2007)
========================
* List of changes between 0.2 and 0.1

Clutter README.
===============
This is Clutter @CLUTTER_VERSION@. Clutter aims to give a nice easy
GObject based API for creating fast, mainly 2D single window stylalised
applications such as media box UI's, presentaions, kiosk style apps etc.
It uses OpenGL for rendering.
This is Clutter 0.3. Clutter is a GObject based user interface toolkit
intended for the creation of fast, visually bespoke and impressive
applications. Open GL is used for rendering.
Its not meant to be a full featured GUI toolkit for regular desktop
apps nor provide a general interface to *all* OpenGL functionality.
It currently uses fairly low end GL functionality with an aim to still
work well on open source graphics drivers as well as possibly making
an eventual GL ES port feasable.
Clutter currently requires:
* GLib >= 2.10.0
* GdkPixbuf
* OpenGL >= 1.2
* Pango 1.x
* OpenGL >= 1.2 or OpenGL ES 1.1
* GLX, SDL or an EGL Implementation
Its also recommended you have some kind of working hardware OpenGL on
your target system.

Release Notes for Clutter 0.4
Relevant information for developers with existing Clutter applications
wanting to port to newer releases;
Release Notes for Clutter 0.3
-----------------------------
* ClutterTexture changes:
+ clutter_texture_set_pixbuf() now takes a GError paremeter.
+ clutter_texture_upload_data has been split into two new and
more functional versions; clutter_texture_set_from_rgb_data(),
clutter_texture_set_from_yuv_data().
* The GLX specific API has been moved to the GLX backend code and
it's now under the ClutterGlx namespace.

reviewed and changed were necessary. Every paint is queued with a
priority of G_PRIORITY_DEFAULT + 10; timelines are allocated with
a G_PRIORITY_DEFAULT + 30 priority; events are processed with a
G_PRIORITY_DEFAUTL priority. This ensures that events are processed
G_PRIORITY_DEFAULT priority. This ensures that events are processed
before the paints take place.

If an application experiences bad behaviours during animations
use "export CLUTTER_TIMELINE=no-pool" to disable the timeout pool.
* clutter_color_parse() now handles color definitions with alpha. Alpha
will default to fully Opaque rather than fully transparent if not specified.
* The Clutter examples/ directory has been removed and replaced with a
tests/ directory.
* Event API changes and event queue (Ebassi) .
* Runtime options now dependant on backend.
HACKING
====
If you want to hack on and improve clutter check the TODO file.
@ -86,7 +106,8 @@ You will need an account.
In the report you should include:
* what system you're running Clutter on;
* which version of GLib, GdkPixbuf and OpenGL you are using;
* which video card and which drivers you are using;
* which video card and which drivers you are using, including output of
glxinfo and xdpyinfo.
* how to reproduce the bug.
