Detailed Description

Txq2dSeg is a finite piece of a curve or straight line which has two end points.

The coordinates of these two points are with respect to the container's coordinate system. The container is assumed to be a Txq2dCanvas. A Txq2dSeg also has the property that it can find the closest intersection point with a given directional line (i.e. an infinite ray starting at a specified point and having a specified slope).

Warning: A Txq2dSeg cannot be painted.
