It's very simple: create a getX() and setX() method for every variable.

You need getDrawBorder() and setDrawBorder() in BgVob, and you need 
protected Color borderColor in AbstractBgVob. And drawBorder should be 
protected.

(And I still think getColors() should return a list-- and colors should 
be initially ``null``...)
