[interfacekit] GraphicsDefs.h addition

Hi there,

does anybody mind if I apply this patch:

As you might have realized, this extends rgb_color. Similar (and more) 
is done in Dano, but I think this is the minimum must have. A SetTo() 
method would be great, too, but for unknown reasons it has been called 
set_to() in Dano, so I wanted to hear your comments first. Since it's 
defined inline anyway, I think we can safely rename it too SetTo()/
Set() without too much annoyance - I never liked Set() because it's 
mostly SetTo() elsewhere, but with regard to graphics, Set() seems to 
be used consistently as well.

Bye,
   Axel.
