From blenderstorm idea# 169 this patch changes the swatch button to display a border showing the keyed status colour
of the colour.
I chose to go with showing the keyed colour in a border around the swatch, insetting the size of the swatch colour to
prevent altering the sizing of the swatch. An un-keyed swatch is not altered visually, only a keyed colour swatch is
changed to have the keyed colour around the outside of the swatch button.
I think a border of 3 pixels is sufficient to make the keyed colour visible without taking too much of the colour area
away.
