Comment:

 Clayton, thanks for the deep testing of this.

 As background, the goal was to refactor cc608, cc708, and text subs into a
 common framework that supports all formatting controls and tries to give a
 consistent look across the subtitle types.  For consistency, cc608 was
 used as the basis since it doesn't offer much flexibility in layout.  The
 original cc608 code included gaps between lines, and that has been carried
 into cc708 and text as well.

 I haven't been able to reproduce issues 1 and 3.  What is your setting for
 OSDSubFont, and what is your playback resolution?  (Mine are FreeMono, and
 1280x720 and 1366x768.)

 Issue 2 is the result of improper CEA-708 encoding.  In this sample, the
 text is anchored relative to the top of the screen, so the first caption
 row should appear at a specific point, but there are no guarantees on
 subsequent rows.  You should see a similar effect in the old code if you
 change OSDCC708TextZoom.

 Issue 4 I plan to leave as it is for now, with future plans to make line
 spacing and other attributes customizable by the theme and/or the user.
