4 This is Clutter @CLUTTER_VERSION@. Clutter aims to give a nice easy
5 GObject based API for creating fast, mainly 2D single window stylalised
6 applications such as media box UI's, presentaions, kiosk style apps etc.
7 It uses OpenGL for rendering.
9 Its not meant to be a full featured GUI toolkit for regular desktop
10 apps nor provide a general interface to *all* OpenGL functionality.
12 It currently uses fairly low end GL functionality with an aim to still
13 work well on open source graphics drivers as well as possibly making
14 an eventual GL ES port feasable.
16 Clutter currently requires GLib >= 2.10, GdkPixbuf and OpenGL >= 1.2.
17 Its also recommended you have some kind of working hardware OpenGL on
20 Clutter is LGPL licensed.

31 Release Notes for Clutter 0.4
32 -----------------------------
34 * The GLX specific API has been moved to the GLX backend code and
35 it's now under the ClutterGlx namespace.
37 * The priority of the various users of the GLib main loop has been
38 reviewed and changed were necessary. Every paint is queued with a
39 priority of G_PRIORITY_DEFAULT + 10; timelines are allocated with
40 a G_PRIORITY_DEFAULT + 30 priority; events are processed with a
41 G_PRIORITY_DEFAUTL priority. This ensures that events are processed
42 before the paints take place.
44 * The ClutterActor::allocate_coords() has been renamed to
45 ClutterActor::query_coords(), in order to clarify its usage.
47 * Actors overriding ClutterActor::request_coords() and
48 ClutterActor::query_coords() must convert sizes obtained from the
49 public API from pixels to ClutterUnits, using the conversion
50 macros found in clutter-units.h. The conversion will be necessary
51 until the public API will switch over to returning the generic
54 * Users of Intel video cards should find that disabling sync-to-vblank
55 is no longer necessary. In case Clutter applications take really
56 long times for redrawing and appear stuck and unresponsive, the
57 sync-to-vblank feature might still be the culprit; in that case, use
58 CLUTTER_VBLANK=none to disable it and file a bug reporting the video
59 card model, the driver version and the X server version.
63 If you want to hack on and improve clutter check the TODO file.
68 Bugs should be reported to the OpenedHand Bugzilla at:
70 http://bugzilla.o-hand.com
72 Under the product "Clutter".
74 In the report you should include:
75 * what system you're running Clutter on;
76 * which version of GLib, GdkPixbuf and OpenGL you are using;
77 * which video card and which drivers you are using;
78 * how to reproduce the bug.
80 If you cannot reproduce the bug with one of the tests that come with Clutter
81 source code, you should include a small test case displaying the bad
84 If the bug exposes a crash, the exact text printed out and a stack trace
85 obtained using gdb are greatly appreciated.
90 Patches should be submitted using Bugzilla. Patches fixing a bug should be
91 attached to the bug report; patches for new features or for fixing bugs not
92 yet reported should be attached to a newly opened bug. Patches should always
93 be in the unified diff format.
