// .NAME vtkOpenGLGL2PSHelper - Helper functionality for GL2PS exporting.
//
// .SECTION Description
// vtkOpenGLGL2PSHelper provides a number of static variables and methods that
// are used during GL2PS exporting. The rational behind this class is that GL
// does not include all of the information that GL2PS needs into its feedback
// buffer, and in certain situations GL2PS function calls need to be made
// alongside their GL equivalents, notably glLineWidth and glPointSize.
//
// The static variables in this class are set by vtkGL2PSUtilities at the
// beginning of a GL2PS export render. This class fakes GL2PS calls like
// gl2psLineWidth in order to keep GL2PS from being a module dependency for
// vtkRenderingOpenGL.

#include "vtkOpenGL.h" // for GL defines.
