Detailed Description

Serialization utilities for geometry objects.

Provides conversion to standard text formats:

• WKT (Well-Known Text): OGC standard for geometry representation.
• GeoJSON: JSON-based format for geographic data structures.

All numeric values are output as doubles (via geom_number_to_double).

Serializes geometric types to standard string formats (WKT, GeoJSON).

This class provides static methods to convert basic geometric primitives like Point, Segment, Polygon, etc., into Well-Known Text (WKT) and GeoJSON representations.

All numeric values are output as doubles (via geom_number_to_double).
