Comment (by philipl):

 Oh, and to state it explicitly: by hard-coding various sizes and offsets
 in the encoders, I was able to produce a file with subtitles that rendered
 correctly in QT 7.3.3 on windows and OSX Player 10.1 (what I was able to
 test with on a Mac I could fine).

 So, the fundamental encoding, with respect to atom types and formatting is
 correct. But in the absence of accurate sizing information, it's not going
 to display correctly.
