Comment:

 (In [15127]) Fixes #4274. Don't draw a completely transparent Teletext
 line.


 This checks a line before we try to render it to make sure that there is
 at least one opaque character on the line, if there isn't we skip it. This
 makes teletext encoded closed captions consume less CPU since only a few
 lines need to actually be rendered (as opposed to teletext menus which
 need to be rendered over the whole screen.)
