// .NAME vtkExternalOpenGLRenderWindow - OpenGL render window that allows using
// an external window to render vtk objects
// .SECTION Description
// vtkExternalOpenGLRenderWindow is a concrete implementation of the abstract
// class vtkRenderWindow. vtkExternalOpenGLRenderer interfaces to the OpenGL
// graphics library.
//
// This class extends vtkGenericOpenGLRenderWindow to allow sharing the
// same OpenGL context by various visualization applications. Basically, this
// class prevents VTK from creating a new OpenGL context. Thus, it requires that
// an OpenGL context be initialized before Render is called.
// \sa Render()
//
// It is a generic implementation; this window is platform agnostic. However,
// the application user must explicitly make sure the window size is
// synchronized when the external application window/viewport resizes.
// \sa SetSize()
//
// It has the same requirements as the vtkGenericOpenGLRenderWindow, whereby,
// one must register an observer for WindowMakeCurrentEvent,
// WindowIsCurrentEvent and WindowFrameEvent.
