What do these mods do?  Jim's note didn't say.  I noticed you
checked in some other changes to change the way single
time fields were handled, but couldn't figure out how to
use them.

The way I do it in the IDV is to have a customized
DisplayRenderer which overrides setAnimationString():

     /**
      * Sets the animation string.  Do nothing if toggled off
      * in the NavigatedDisplay.
      * @see NavigatedDisplay#setAnimationStringOn(boolean)
      */
     public void setAnimationString(String[] animation) {
        if (navDisplay != null && !navDisplay.getAnimationStringOn()) {
           animation = new String[] {null, null};
        }
        super.setAnimationString(animation);
     }

(full source is attached, should make the 40k limit).  Maybe this
could be rolled into DisplayRenderer somehow with a
set/getAnimationStringOn() method just like we have
set/getCursorStringOn()?  At one point, this was the only
reason I needed a custom DisplayRenderer for these classes which
seemed a lot of work to go through just to turn off the
animation string.

Actually, looking at the code for setCursorStringOn, it looks
like all it might take is adding this to DisplayRenderer?:

   private boolean aniStringVisible = true;

   /**
    * Set whether the animation info should be visible in the display
    * or not.
    * @param  visible  true to show the animation info
    */
   public void setAnimationStringVisible(boolean visible) {
     aniStringOn = visible;
   }

   /**
    * Return whether the animation info should be visible in the display
    * or not.
    * @return   true if the animation info should be shown
    */
   public void getAnimationStringVisible() {
     return aniStringVisible;
   }

   /**
    * Return Array of <CODE>String</CODE>s describing the
    * animation sequence
    * @return The animation description
    */
   public String[] getAnimationString() {
     if (aniStringVisible) {
       return animationString;
     }
     else {
       return new String[] { null, null };
     }
   }

If it's that simple, maybe we should do it.
