Double Buffer Enable
This bit enables the Double Buffer architecture.
When this bit = 0, the double buffer is disabled.
When this bit =1, the double buffer is enabled. This feature is only available if the memory
size resulting from the display size and color depth will fit within the 1/2 the allowable
size for the display buffer.
When enabled, this feature is intended for streaming input sources to prevent visual tear-
ing when updating the display.
This bit must be set before the window being written. The window coordinates will be
latched internally to be used by the display pipe during display cycles.
While double buffering is enabled, the window coordinates should not be modified.
Only one window can be double-buffered. All other windows are single buffered.
