Expand description

Extended draw interface for DrawIface providing shaded drawing

This trait is an extension over DrawImpl 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.

Methods 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.
