[vtkusers] 3D model and 2d Image overlay - depth issues, flickering

[Miro Drahos]

Try to keep just one camera and set the other renderer to it:

ren2->SetActiveCamera(ren->GetActiveCamera());

Also, do you really need all these

rw->SetWindowId(hWnd);   * //rw is vtkWin32OpenGLRenderWindow*
rw->SetParentId(hWnd);
rw->SetDeviceContext(hDC);
rw->SetContextId(hRC);

Why not just create vtkRenderWindow and let VTK deal with the device/OS 
specific-issues?

Cheers,
Miro
