[OpenJDK 2D-Dev] RFR: 8178457: Remove link to 2D guide from Line2D javadoc

[Jim Graham]

It's silly to include this statement in Line2D when no other geometry class bothers to mention this.  It is considered 
assumed information if you've gotten far enough to be looking at this class.  I would prefer to copy boiler plate from 
one of the other Foo2D geometry classes instead...
