This is all the reftests I've finished. Outstanding tests include positioning cues with right-to-left test. There appears to be a bug in the specification. Overlapping cue tests need to be written. Tests for the tags ruby, class, and voice are not done. In addition, there are no tests for new CSS properties such as ::cue.

This contains the following tests:
Test the default behaviour. No particular rule. (April 17, 2013)
basic

Make sure cues do not render for the audio element. (April 17, 2013)

Make sure control interface and cue do not overlap. (April 17, 2013)
controls

Ensure cues display in the correct order for multiple cues and tracks. (April 17, 2013)

Cue writing direction, alignment, and writting mode tests. (April 17, 2013)
The rules for direction, alignment, and mode depend on each other
so tests for each individually would be the identical.
There is a specification bug for positioning cues with right-to-left text. Those tests need to be done.
