+% Now we draw the genus path, outside the clip.
+% We view this as part of the full cobordism path so try to apply the same style as for the full path, but if that is filled then we turn the fill off.
+% It can be turned back on again using the styles \verb+cobordism edge+ or \verb+genus style+.
+% We also apply the \verb+cobordism edge+ style as it could be thought of as part of the non-boundary edge.
+% Finally, it has its own style to enable overrides if the other two get confused.
