This should handle displaying the text cues on the page. This is given the
cues to display and told when to start and stop displaying. This should only
display the cues it is given and remove cues when told to.
This should only change whether it is displaying the cues through the
setTextVisibility function; the app should not change the text
visibility outside the top-level Player methods. If you really want to
control text visibility outside the Player methods, you must set the
streaming.alwaysStreamText Player configuration value to
true.
