/**
* Renders the molecule set using plain OpenGL. Can be instantiate for
* display of molecules or molecule-sets using the template parameter.
*
* \internal This class delegates the actual task of creating scenegraphs
* and rendering it to an OpenGL context to the NXOpenGLRenderingEngine_delegate
* class. The task of the template parameter is to filter what can be
* displayed through this window and much of the rendering part is independent
* so maintaining a template-less delegate is better code reuse.
