/**
* @class vtkExternalOpenGLRenderWindow
* @brief OpenGL render window that allows using
* an external window to render vtk objects
*
* 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.
* \sa vtkGenericOpenGLRenderWindow
