There's a function in Gorm (Palettes/2Controls/inspectors.m) which 
returns the button type for a button. Perhaps we could put that in gui 
if it is useful.

Well, I'd like to make themes easier also, but I don't know the best way 
to do it. Perhaps redoing the background and frame drawing functions so 
they can be overridden, or perhaps specific (and documented) drawing 
methods for different widgets. I was hoping someone could take the time 
to look at how other systems implement themes and adopt that to GNUstep.
