Stipple shading is used throughout to show surface contouring and as an aid to determining boundaries between claimed subject matter and unclaimed environmental structure; unclaimed environmental structure is not shaded or hatched, whereas claimed subject matter is shaded or hatched. It is to be understood that the use of stipple shading does not convey any particular surface finish or surface texture, but is merely used as an aid to show surface contouring and the extent of claimed subject matter. In views where no natural boundary exists between claimed subject matter and unclaimed environmental structure, dashed-dotted-dashed lines are used to indicate such boundaries. For further clarity, tangent lines indicating smooth transitions between surfaces are depicted in grey dashed lines (short-short-long dashes). Broken lines, such as dashed and dotted lines, are used to indicate unclaimed environmental structure. In cases where broken lines are used to represent features on a shaded surface, it is to be understood that the surface itself is still claimed but that the particular structures on that surface are unclaimed environmental structure.
