HI Ed,

Thanks for the effort.

Reg Adding checks:

With X fix in, it boils down to whether we want to support
--no-tiled-backing-store or not.
AC checks make sense to me (unless we decide not to support non Ac
composition mode on UI process side.). Coordinated graphics checks
seem un-necessary
as most of the classes are WebKit2 related. Someone more familiar with the
code might think otherwise :)

Reg Reviewers:
You already have Laszlo,* Gyuyoung Kim participating in the discussion.
Kenneth, MIkhail are already in cc.

*As you have already split the patches to smaller ones, you might want to
create new bugs to each one and make the current one as blocked by others.
This would at least help to focus the discussion for that particular check.
(i.e coordinated graphics, tiledbackinstore and AC )
