// .NAME vtkGenericOpenGLRenderWindow - platform independent render window
// .SECTION Description
// vtkGenericOpenGLRenderWindow provides a skeleton for implementing a render window
// using one's own OpenGL context and drawable.
// To be effective, one must register an observer for WindowMakeCurrentEvent,
// WindowIsCurrentEvent and WindowFrameEvent. When this class sends a WindowIsCurrentEvent,
// the call data is an bool* which one can use to return whether the context is current.
