vtkCameraActor enhancement
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
It would be nice to know the orientation of the frustum that is produced by vtkCameraActor. Maybe the edges of the frustum could be colored to indicate the "top" (or view up) vector?
Also, the size of the frustum needs to be different based on the size of the scene that it will be placed in. Could there be some kind of SetLength function that sets the length of the frustum from the front plane (or tip) to the back plane?
