Remarks
This class is closely connected to TGIS_Viewer, so never construct it independently.
The basic editing functionality includes the moving of points, moving vector vertices, creating new vector points, line, and polygons, deleting vector points and vertices, snapping, with mouse clicks.
Various objects were declared in Pointer manner to avoid circular references.
