-/// @brief Implements cluster culling to cull back facing drawables. Derived from Drawable::CullCallback.

-/// This culling callback is intended to be attached to a node using the setCullCallback method. If the
-/// node is a drawable cull(osg::NodeVisitor*, osg::Drawable*, osg::State*) otherwise
-/// operator()(Node*, NodeVisitor*) will be called during the cull traversal.
-///
-/// To decide whether the node (in case of a drawable) or its children (in case of any other node type) are

-///  - a control point,
-///  - a normal specified at the control point,
-///  - a deviation value representing the cosinus of an enclosed angle and
-///  - a radius describing a sphere around the control point.
-///
-/// The node is culled if the following two conditions are fulfilled:
-///  - the distance between the current eye/view point to the control point is larger or equal to radius,
-///  - the cosinus of the enclosed angle between the normal and the vector from the control point to the eye/view point
-///    is smaller(!) than the specified deviation value (normally this value is negative meaning that the enclosed angle
-///    between the control point and the eye/view point is larger than the angle indirectly specified by the
-///    deviation value).
-///
-/// @remark As the deviation is representing the cosinus of an enclosed angle its value should be within the
-///         the interval [-1; 1]. A value of one will cull all nodes while a value of -1 will never cull a node.
-///         The deviation will normally have negative values because then the enclosed angle between the normal and the
-///         eye/view point is larger than 90 degrees (and therefore the eye sees the "back" from the control point).
