Some operation may have different semantic depending on which boundary node rule is applied.

See ​http://www.vividsolutions.com/jts/javadoc/com/vividsolutions/jts/algorithm/BoundaryNodeRule.html for background information.

GEOS C-API only expose boundary-node-rule in the GEOSRelateBoundaryNodeRule, introduced in 3.3.0. But more functions would be affected by such rule these are:

• Relate (we have GEOSRelateBoundaryNodeRule since 3.3.0)
• Boundary
• isSimple
• Touches
• Within
• Contains

It would be useful to expose a way to specify the boundary node rule for each of the above operations
