Drawing commands for shaded shapes

This trait is an extension over Draw providing solid shaded shapes.

Some drawing primitives (the "round" ones) are partially transparent. If the implementation buffers draw commands, it should draw these primitives after solid primitives.

These are parameterised via a pair of normals, (inner, outer). These may have values from the closed range [-1, 1], where -1 points inwards, 0 is perpendicular to the screen towards the viewer, and 1 points outwards.
