I don't think we care that much about ERR vs. FIXME for winediag. Note
that this isn't necessarily something we or anyone else can fix. The
wined3d core context work will make d3d10+ work on Mesa and MacOS for
some classes of cards, but there's also plenty of hardware that's
simply incapable of shader model 4. In that regard this isn't all that
different from the situation with hardware/drivers that can't do
shader model 3.
