[ttml2] writingMode and direction interaction

palemieux has just created a new issue for 
https://github.com/w3c/ttml2:

== writingMode and direction interaction ==
Style inheritance propagates `direction="ltr"` (the initial value) on 
all elements (unless explicitly specified as "rtl" somewhere), thereby
 overriding any right-to-left direction specified using `writingMode` 
on region, since, as specified in Section 7.29.1 of XSL, `direction` 
takes precedence over `writingMode`.

As specified in Section 7.29.1 of XSL, the TTML style resolution 
process needs to specify that, whenever specified, `writingMode` also 
sets the value of `direction` to the horizontal direction implied by 
`writingMode`.
