## OpenGL tools

renderingMode - Controls the way OpenGL renders objects.
light - Controls the use of lights in the rendering window.
text - Enables capabilities to write some text on rendering screen.
view - Defines all necessary informations for the rendering of a view.
interactive - Gives tools to interact with the rendered area.
objectList - Gives storage for ids used by OpenGL lists.

These little utilities are dealing with OpenGL. They are not essential to V_Sim but can add some nice features that can be shared between different modules.
