Comment 1 for bug 609787

I've attached a mockup of how I think it should look. Otto would be the best person to refine that to exact pixel positioning and colours. Otto, I've just used two one-pixel lines, a dark and a light one, to create the groove. Please could you refine and specify for Mirco? But a groove is the desired edging.

Also, for the avoidance of doubt, specify the horizontal position of the groove relative to the edge of the launcher. I suspect we will need a precise pixel-perfect spec of the launcher edge effect and the panel Ubuntu button groove.
