Logic to face vtkCamera at an image should be refactored, and generalised to arbitrary image planes.

In vtk_overlay_widget there is logic in __update_video_image_camera. This positions the camera to face an image, but assumes the x and y axis are fixed.

For applications where you want a vtkActor to move in one window (eg. tracked US probe), but in another window for the camera to always face the image, then the logic in __update_video_image_camera should be generalised to accept images that are at an arbitrary dimension.

Implemented in NifTK here.

This should still be done if possible

Hi @MattClarkson and @thompson318 amd @tdowrick

Shall we close this one? In the meantime, I labelled as low priority.

Thanks
