Clutter is a library for creating compelling, dynamic and portable graphical
user interfaces. Clutter is released under the terms of the GNU Lesser
General Public License, version 2.1 or (at your option) later.

  Atk ≥ 1.17
  OpenGL ≥ 1.3 (or 1.2 + multi-texturing), OpenGL|ES 1.1 or 2.0
  GLX, WGL, Quartz, or an EGL implementation

Clutter also has platform-specific dependencies; for more information, see
the README file included in the release.


Release Notes:
  - This is an unstable snapshot of Clutter; there are no compatibility
    guarantees for API added during a development cycle.
  - 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 release of Clutter.
  - Bugs should be reported on the Clutter Bugzilla product, at:

    - Unify the GLX and EGL backends to be a single code base
    The GLX and EGL backends shared most of their code, and with the split
    out Cogl, we can unify the code base into a single backend. The API as
    well as the ABI are preserved.

    - Restore a wider range of Z values for actors
    The computation for the near and far planes given the perspective
    transformation used to set up the viewport was broken in 1.7.2, and
    the distance from the focal point was greatly reduced. This has now
    been fixed.

    - Bump up the dependency of Cogl
    New windowing system API in Cogl required bumping the minimum version
    to the latest development snapshot, 1.7.2.

    - Add ClutterDropAction
    The ClutterDropAction is an action for allowing ClutterActors to react
    when an actor being dragged through ClutterDragAction crosses, or is
    dropped over, them.

    - Add a performance test suite
    This suite is an addition to our conformance and interactive test
    suites; the infrastructure can be used by buildbots and report tools
    to track performance regressions across various commits.

    - Documentation and annotation fixes

    - Build fixes
