<a name="overview"></a><p>
        Graphene is a library of data types commonly used to implement 2D-in-3D or full 3D canvases.
      </p>
<p>
        Graphene only contains math data types, like vectors and matrices; it does not deal with windowing
        system calls, event handling, drawing, or a full scene graph.
