Things like not using direct rendering, or using a software renderer
indicate a badly configured system most of the time, but aren't
necessarily wrong or fatal. In that sense winediag messages would
always be WARNs, because real errors or FIXMEs would go to the regular
debug channels anyway. But then no regular user is going to see them
unless they use the non-existent GUI. I think ERR should be reserved
for real errors, so that e.g. triggering ERRs in the tests would be
equivalent to introducing failures. Most of the time that's already
true, but there are places that use ERR for things like invalid values
passed by the application, that really don't deserve more than a WARN.
