 * <p/> This class makes up a shell display system with no functionality. It is
 * here to allow the easy creation of renderer-agnostic jME objects (like
 * various RenderState and Spatial) so that they can be used by conversion
 * utilities to read/write jME. It is <b>NOT </b> to be used for rendering as it
 * won't do anything at all.
