/*
		Using a pixmap for geometry description

This file can be used also as a pattern to define your own geometry
descriptions is you want to use an own RegionOfPoint function.

The implementation of a geometry is a C implementation of C++ schemes.
Your geometry can be considerd as a derived class of the basic class
CogeometryRec. This class contains a pure virtual method RegionOfPoint and
other virtual methods. To create a geometry you have to define the derived
class, to implement the pure virtual method RegionOfPoint and at least one
constructor. You can also implement other versions of the other virtual
functions.
