[vtk-developers] vtkOpenVRRenderWindow and vtkWin32OpenGLRenderWindow

[Ken Martin]

Make sure you also explicitly create the OpenGL/OpenVRCamera for each
renderer as they are different. And I would create the
OpenVRRenderWindowInteractor Win32OpenGLRenderWindowInteractor explicitly
and assign them. Those are the 4 key classes you have to explicitly create
as leaf nodes

OpenVRRenderWIndow
OpenVRRenderer
OpenVRCamera
OpenVRRenderWIndowInteractor

Win32OpenGLRenderWindow
OpenGLRenderer
OpenGLCamera
Win32OpenGLRenderWIndowInteractor
