So what ? Everybody knows that ;-)
Wine has to go through the X server, which probably isn't blazingly fast by
itself, and then the X11 graphics operations are sometimes incompatible
and have to be "emulated" somehow, and then keep in mind that Wine is
everything but complete.
When (or rather: if !) it gets there, then we'll strongly care about speed
issues.
But keep in mind that it won't exceed Windows GDI speed via X11 anyway, since
Windows can have its own and very customized and very optimized graphics
engine.
If you want blazingly fast Wine GDI speed, then what about writing another
graphics driver ? (for GGI, Berlin, ...)
The infrastructure already kind of exists anyway...

Again, so what ?
It *runs*. And that's the main point.
And if it runs even faster than VMWare, then it's glaring success ;-)

Sure.
I know that e.g. controls/static.c is horribly broken.
I'll fix it very, very soon.
(it affects many programs)

Well, if there isn't anyone actively supporting GDI:
what about getting active ON YOUR OWN ? :-)
I always hear claims that "Wine sucks, it doesn't run this or that, doesn't
do this or that, yaddayadda ...".
But the number of people that are *actually* contributing is still pretty poor.
Not even the documentation is being properly maintained, which even people
not too experienced with programming could do without a hell of a lot of
trouble.
