MeVis OpenGL Information Interface (Singleton)
At MeVis we use the GLEW library, which is initialized in the init() call of this class. In addition to the API provided by GLEW, this class has some additional methods that give information on the underlying OpenGL system. All methods of this class can be called WITHOUT having a valid OpenGL context, given that the init() method was called once at program startup. Projects that use the OpenGL API or extensions should typically specify
in their profile and include
This will also include the appropriate GLEW OpenGL header files.
