Detailed Description

Base class for all "basic" shapes.

Prerequisite

DisplayShape

Etymology

DSBasic is a base for all basic classes, it manages linewidth.

Synopsis

DSBasic is a base class for any shape using basic lines to draw it self, i.e. shapes such as lines, circles and polygons should extend this class. More complex DisplayShapes, e.g. text should not.

Motivation

A common interface for the setting of linewidths
