This is a misunderstanding. Codeweavers figured out that they do not
*need* the DIB engine aka it isn't the bottleneck. The estimates to get
it implemented/merged where 6-12 man month of "architect level" Wine
developer time. A huge time investment for little gain and thus
Codeweavers decided to invest their resources in other areas that have a
higher return of investment.
Now people keep asking about the DIB engine and how to motivate
Codeweavers to work on that. I replied to that that in my *personal*
opinion they won't do that unsexy and costly work unless somebody is
waiving at them with some serious amount of money. That's the standard
way in the enterprise world of rising the priority of a bug. But this is
my *personal* opinion; I never ever have seen a Codeweavers employee say
something like that. And I know Jeremy, he would *love* to get a DIB
engine for free, especially as he knows its value in $$$ ;)
Now that "that waive with $$$" isn't very likely as the cost/benefit
ratio isn't very good. More likely is that Codeweavers will start
working on a Quartz driver and that work will make the DIB engine
"cheaper" to implement. Again, this is my *personal* opinion.
