Well, I would have argued that extent() not returning what you'd expect 
it to would be a source of bugs and much head-scratching, but I notice 
that you've added some documentation that says exactly what it does do, 
so that's probably good enough.

Yes, I was only using QColor as that is what is used at the moment until 
KisColor or such appears.
