ISSUE-355 (marquee): Add support for marquee style semantics [TTML2]

http://www.w3.org/AudioVideo/TT/tracker/issues/355

Raised by: Glenn Adams
On product: TTML2

ARIB-TT [1] defines an extension [2] to TTML to allow author to specify marquee semantics. Yoshiharu Dewa (Sony) suggests [3] this feature be supported by TTML.

Before considering adding a marquee style, however, we need to investigate if the new animate element could be used to express equivalent semantics.
