Clutter is an open source software library for creating portable, fast, compelling and dynamic graphical user interfaces. Clutter is licensed under the terms of the GNU Lesser General Public License version 2.1.

Requirements

• GLib >= 2.18.0
• Cairo >= 1.6
• Pango >= 1.20
• Atk >= 1.7
• OpenGL >= 1.2 + multi-texturing, OpenGL|ES 1.1 or OpenGL|ES 2.0
• GLX, WGL, Quartz or an EGL Implementation

Depending on the platform and the configuration options Clutter also depends on:

• GDK-Pixbuf >= 2.0
• JSON-GLib >= 0.10

Release Notes

• This is the third developers snapshot of the 1.3 cycle.
• Given the changes occurred in the Cogl material implementation, there can be issues and breakage with existing code; some of these issues are known, and we're working towards fixing them.
• This version is API and ABI compatible with the current stable release of Clutter.
• Installing the contents of this release will overwrite the files from the installation of the current stable release of Clutter.
• Bugs should be reported on the Clutter Project bugzilla.

What's new in Clutter 1.3.6

List of changes since Clutter 1.3.4

• Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not available, by using EXT_framebuffer_blit. Both mechanisms are also throttled to avoid taking all resources when using them in a compositor like Mutter.
• Use (and cache) fragment shaders instead of texture combiners inside Cogl materials. Cogl will automatically fall back from GLSL to ARBfp to fixed functions depending on the level of support of the underlying GL implementation.
• Implement a new design for materials; this allows scaling up the number of materials in a scene, and also makes copying materials less expensive.
• Make Cogl materials responsible for depth testing, and add new experimental API.
• Use the (modified) GLU tesselator to draw paths to a vertex buffer object instead of using the stencil buffer, or the scanline rasterizer on platforms without a stencil buffer.
• Add ClutterDeformEffect, a base class for effects that deform an actor's geometry when painting it; ClutterPageTurnEffect is an implementation of a "page curl" deformation using the DeformEffect API.
• Always use scissoring when clipping, to reduce the amount of buffer that has to be cleared.
• Allow ClutterShaderEffect sub-classes to use vertex shaders by setting a constructor property; the default remains fragment shader.
• Remove the button of the press event from the DragAction::drag-begin and DragAction::drag-end signals. This is an API break from 1.3.4.
• Do not promote clipped redraws to full redraws.
• Improve the consistency of the default state name in ClutterState, both in the API and in the serialization format.
• Fix a rounding error with the Text layout size.
• Add utility functions for CoglMatrix and CoglColor.
• Avoid a re-allocation cycle warning when resizing the surface of a CairoTexture actor from within the allocate() implementation.
• Do not add the GL libraries for the EGL X11 backend.
• Add more checks for size of data passed to the shader types GValue functions.
• Add width and height to the BindConstraint.
• Parse actions, constraints and effects inside an actor definition for ClutterScript.
• Merge the code of native and x11 backends for EGL into a single backend; also allow creating GL context with the EGL backend.
• Use XSETTINGS to set up the backend configuration options, like the font name, resolution, font options and double click options, on X11; this also allows ClutterText actors created using the default font name to be updated when the font name and options change; similarly, this allows ClutterUnits to be updated when the screen resolution changes.
• Implement the texture_from_pixmap extension support inside Cogl itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
• Documentation improvements in the API reference and in the cookbook.
• Use the -Bsymbolic-functions linker option on supported platforms to avoid intra-library PLT jumps.
• Fix painting transparent stages on X11 using the :use-alpha property of ClutterStage.
• Fix emission of scroll events on Windows.
