Comment (by kneufeld):

 Thanx Mateusz.  I fixed the typos and add your noted references at the end
 of the section.

 I like the pdf doc by Christian Stobl.  Nice.  I hadn't seen that one
 before.  I was thinking along the same lines and would eventually like to
 see a simple de9im matrix in every spatial predicate definition (touches,
 crosses, within, etc) just as Christian has done in his doc. ... someday
