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.
