[geos-devel] A word about Javisms

[Paul Ramsey]

I should point out here, that the JTS relationship has been virtuous  
in both directions. The GEOS community has had performance issues  
which for some reason the JTS using community has not, and this has  
resulted in a number of efficiency ideas which have migrated from the  
GEOS list and implementations back into JTS as Martin saw the merit  
in them.  (Primarily rather simple short-circuit ideas which were not  
required for JTS correctness but make a big difference in the Real  
World when things start getting exercised.)
