Comment 7 for bug 592578

Whilst creating some modules today I found that this feature is already implemented, you can map a graphic to any of the existing pcbnew layers. However it's hidden under under the context menu in the module editor.

When adding a graphic to the module by default it's on the silkscreen layer, if you right click on the graphic | edit | edit layer (current), then edit you can assign it to any of the other layers. However this process needs to occur for each segment you want on different layers.

To make this more intuitive I think the module editor needs the layer manager to be displayed with the same functionality as PCBnew, i.e. selecting layer before starting to draw, or turning layers display on/off.
