I am seriously unimpressed with the fonts I am provided with, but > I haven't tried to work around them yet) Font rendering will be done by Wine via the XRender extension or so soon, I believe. We can't rely on X11 font rendering anyway, since this doesn't give us access to the font metrics itself. And X11 font rendering is pretty damn incompatible at times. That's why we need to roll our own (for local display, *not* for remote displaying !) >> what about getting active ON YOUR OWN ? :-) > I'd love to. I think wine is a good idea.

I'd much rather see it use one or several of the pretty advanced "native" Linux alternative display drivers instead of having to use X11 exclusively. So if you want to add a driver for a different display driver system to Wine to map the GDI stuff on that, then just go ahead ;) (again, shouldn't be too horribly difficult, since the infrastructure is already kind of in place) > jeremy > P.S.
