   I've totally forgot about the history link, sorry. And filed new issue (not to forget next time) as
https://github.com/w3c/ttml2/issues/1227

   For i18n gap-analysis, there is a matrix summarizes gaps, at: https://w3c.github.io/typography/gap-analysis/language-matrix
   Shear or Italic is handled in 'Font styles', and two are pointed as issue (italic in rtl),
Arabic: https://github.com/w3c/alreq/issues/218 (incl. graphical sample)
N'Ko italic: https://github.com/w3c/afrlreq/issues/17 (incl. graphical sample)
both uses the matrix pointed in #1199 (CCW for rtl).
   both clreq (zh -hans/-hant) and jlreq does not have any section about italic/shear.

   I have no information on center or edge for now, which results into a half character width
shift at the beginning...
