If this code is called because some other wined3d code doesn't honor the limits this should be fixed elsewhere. If this code is called correctly, and catching the limit violation in the state setter is the correct thing to do this should be a TRACE(e.g. the state handler is called because device creation dirtifies all states).

Yeah. A rather old one... ;-)

I don't know this code much but I would say it is partly 2 and 3. Is a 
FIXME suitable then ? This would be much more informative that just GL 
errors.
