Auto-Image

When Auto-Image is performed, the DSC attempts to size and position the image to fill
the display screen (fill mode) or use the native aspect ratio of the input (follow mode).

the current input.
Only the horizontal and vertical positioning and the horizontal and vertical size are
adjusted by the Auto-Image. All other controls are left unchanged.
