#### Description [src]

Backend abstraction

Clutter can be compiled against different backends. Each backend has to implement a set of functions, in order to be used by Clutter.

`ClutterBackend` is the base class abstracting the various implementation; it provides a basic API to query the backend for generic information and settings.
