   LocalVideoFrame - A video frame for when the data is local snd should be
                     managed by the program instead of the system. Uses Image
                     to manage the memory. Programs which will only ever use 
                     these can be optimized by using the image() methos. These
                     can be deleted sensibly, but it is not currently allowed, 
                     to make the interface more consistent.
