// .NAME vtkOpenGL2ContextDevice2D - Class for drawing 2D primitives using
// OpenGL 2.
//
// .SECTION Description
// This class takes care of drawing the 2D primitives for the vtkContext2D class.
// In general this class should not be used directly, but called by vtkContext2D
// which takes care of many of the higher level details.
//
// It assumes that OpenGL 2 is available, which is taken care of by the
// vtkContextActor class. If OpenGL 2 is not available, but OpenGL rendering is
// required the vtkOpenGLContextDevice2D class should be used (employs GL 1.1).
//
