Thanks for the pointer Jason. I agree with the solution you and Eskil
agreed upon in the last comments there (that setting styleName _and_
weight, it will stick to the styleName specified, but use synthesized
bold to reach the desired weight).
Just one thing: It must at all times be possible to avoid synthesizing
of weight. If I specify styleName, but _not_ weight (nor the bold)
property, then it should not do some synthesization to reach normal
weight (the default weight according to docs).
I don't think Eskil has this in mind, since it wouldn't really makes
sense, so I'm not worried. Just wanted to be clear :)
