Add a possibility to draw a background bounding box behind a color bar
I generate a lot of pictures which have color bar using ParaView. I miss one functionality which is a possibility to draw a white rectangle between the 3D scene and the color bar. This help at providing more contrast between the data and the color bar if the data happens to be displayed behind the color bar.
For example, in this figure, I would like to have a white background behind the color bar.
I am not sure how much work that is though.
