Detailed Description

Shared OpenGL context.

CX use a shared OpenGL context for all render windows. This is a hack added to our branch of VTK. See vtkXOpenGLRenderWindow (Linux), vtkCocoaRenderWindow (Mac), and "vtkSomething" (Windows)

There exist only one shared OpenGL context, and this is set to be the id of the first context created by vtkRenderWindow. All vtkRenderWindows created gets this shared context. This means that the first vtkRenderWindow MUST NOT be deleted, as it contains THE OpenGL context.
