I read the thread starting at [1], and it looks to me like they're
just beginning to agree to do it and that none of the three otlayout
[2] in FT's CVS tree is joint work (yet).

That thread does show me that Pango forks FreeType [3] as well as
using it.  While it would be nice to speculate about the possibility
of getting baseline table support into the Pango OT code before Pango
OT support is merged into an eventual OTLayout, I can tell you now
that I don't have time to do it myself.

So it looks like xmlroff should drop dominant-baseline, etc., until
Pango uses an OTLayout and OTLayout supports parsing of baseline
tables.

Tony.
