All "Hold Frame" options will continue to output the last valid display
frame after the decoder has stopped. That frame will not be removed until the
decoder is restarted for a new decode session. At startup, the system will use
the specified "Hold Frame" startup option for the output. For instance,
option HOLDFRAME_BLANKTONE will output bars and tones after a reset until
the decoder has started. After that, 'Hold Last Frame" mode will be enabled
whenever the decoder is inactive.
