Detailed Description

A model-like object that draws a 2D line.

A 2D line that can be represented in one of two ways: either it has a start position and end position, divided into segments, or it is multiple (> 2) vertices, each pair of which define a segment. Each segment consists of a percentage (first case only), color, style, arrow style, stipple pattern, and thickness.
