The G2S (two-dimensional geometry support library) was designed to
provide geometry related functions. These functions include basic checks on
geometries as well as manipulation functions to insert or delete geometry
elements like points, lines, faces, boundaries, or segments. It defines
functions to query topological information like the boundary of a segment, or
the faces that share a line. By defining its own data representation and
implementing its own interpolation mechanism (the so-called slab
method [9]) it does not profit from the functions and data structures
provided by the GRS module. Therefore, the grid lists in a PIF file are
completely ignored. Inconsistencies that are eventually introduced by
manipulating the geometry are not detected by either the GRS or the G2S module.
