Part border on image

[Beat Cornaz]

I use images (in a  rectangle form) as sliders to get a minimum and 
maximum value. I want to get a border at the bottom of the image (or 
at the top). I use images because of the blend property. The 3D 
border won't do, as it is bottom and right side.

Of course I can introduce a separate line object to do the job, but I 
need to keep it as simple as possible, because it is getting already 
complex enough, without making groups with images and lines.

Also : I don't understand the first to eight color. Doesn't that work 
with images? In the inspector of an image I can select colors for 
first color etc. but nothing changes . If I go back to the inspector 
of that image, the color I've chosen are gone as well.

I can't manage do give a radio- or check button a color. The name, 
ok, but the button itself doesn't react to any color adjustment I 
make.

Thanks, Beat
