// .NAME vtkExternalOpenGLCamera - OpenGL camera
// .SECTION Description
// vtkExternalOpenGLCamera is a concrete implementation of the abstract class
// vtkCamera. vtkExternalOpenGLCamera interfaces to the OpenGL rendering library.
// This class extends vtkOpenGLCamera by introducing API wherein the camera
// matrices can be set explicitly by the application.
