  34 /*  FUNCTION
  35         Controls video output. It currently only allows adjustment of
  36         power-saving modes, using the following tag:
  37             SETVC_DPMSLevel (IPTR) - one of the following DPMS levels:
  38                 DPMS_ON - normal operation.
  39                 DPMS_STANDBY - less than 80% power usage.
  40                 DPMS_SUSPEND - less than 30W power usage.
  41                 DPMS_OFF - less than 8W power usage.
  42
  43     INPUTS
  44         vp - a ViewPort belonging to the video output device to be controlled.
  45         tags - a taglist containing video control options.
  46
  47     RESULT
  48         None.
