00:00.000 --> 00:10.000
this is a cue

STYLE 00:00.000 --> 00:01.000 (or whatever the syntax would be)
color: red;

STYLE 00:01.000 --> 00:02.000
color: green;

And so on. It would mean that now it's not just the start and end of
cues that would have to tracked, but one would also need a separate
list of timed stylesheets and some way of removing stylesheets at
their end times.
