I've just committed changes for this font-backend mechanism
in emacs-unicode-2 branch. As I added two tags before and
after the commit, you can see what are changed by:
% cvs diff -Nu -r unicode-pre-font-backend -r unicode-post-font-backend
The reason I dared not make a new branch is that the new
codes don't affect the current behavior of emacs-unicode
unless you configure with "--enable-font-backend" and run
Emacs with the same arg. README.unicode contains some more
information about the changes.
We still need many more works to make using of font-backend
the default. But, before going ahead, I'd like to ask
people working on Windows and Mac porting to check if the
current mechanism (APIs of font-driver) is sufficient for
native fonts support.
I think it is better to use address@hidden (not
address@hidden) for the further discussion on this
matter to avoid disturbing the works for the official
realease. So, people who are interested in it please join
emacs-unicode mailing list. For that, as far as I remember,
Eli <address@hidden> can handle a request of subscribing.
Eli, is it right?
