Surprised too about lack of information, but anyways.... who cares ?
Soon or late it'll be completed, I hope soon, of course.
I've *not* looked at current Huw's implementation.... I lost interest in DIB
engine long time ago. It's just a pity that my patchset got broken, so who
needs the "old" dib engine should stay with an older wine version too.

I just tested the actual implementation, but, for my purposes, it doesn't speed
up anything. Your mileage may vary, of course.
AFAIK, most of apps needing it needs font drawing speedup, and there's still no
trace of dib font drawing in new engine, and that one isn't a trivial task.
My engine implemented it with some glitches, but at least it was usable.
Also, I've got no idea if Huw is grabbing something of my code or not, but I
guess not.

BTW, as a user, I would have liked something a bit more useful, or at least
something which wouldn't break completely the "old almost working engine", as
many people used it, but of course it's not under my control.
Nor I've time to rebase the old one on current three, mostly because, as far as
I can see, the interface is still changing too much and it'll be a very time
consuming task.

So, cross your fingers (as usual) and hope :-)

Ciao

Max
