Curve support is handled by parsing curves into LineStrings on the fly. The
linearization tolerance helps decide how many segments are needed when a
curve is converted into a LineString (so changing this value should change
the number of coordinates available).
Is it possible that we accidentally switched from the GeoTools WKTParser
(which handles this stuff) to the JTS WKTParser which is unaware? We played
some silly games to make the GeoTools one extend the JTS implementation
(even though they do not share much code due to the design of JTS).
