Taking a look at that now.  There is rather a lot of deprecated API use
there that I will have to clean up first.  The ast driver which I was
tracking does not seem to have had much clean-up recently - qxl might
have been a better choice.  I will also want to get our local code at
the level of your v4 submission before I start to avoid creating
unneeded difficulties.

By the way, see a small, as yet uncommitted fix below.

Regards
Michael
