ShapeFactoryImpl should have an option for expandBufForLongitudeSkew on a buffered line.

[dsmiley]

ShapeFactoryImpl ought to consistency pass expandBufForLongitudeSkew to BufferedLineString's constructor. lineString(points, buf) passes ctx.isGeo() (seems appropriate) whereas LineStringBuilder always passes false (seems wrong). Moreover, this ought to be a setting that's plumbed on in through the SpatialContextFactory and parsed there.
