Description

Self-intersecting shapes cannot be tessellated and currently throw a generic like:

 

 

  Unable to Tessellate shape...

 

In case of Self-intersecting shapes we can do better and try to give a more useful message by detecting the self-intersection position and provide that information to the user.
