Detailed Description

Implementation of a 2D (overlay) Arc Facade.

This class creates and initializes a DtOverlayArcModelAgent and adds the model to its parent DtSceneObjectAgent (which is created in or passed into the class's constructor).

This implementation draws an elliptical arc with the following geometric parameters:

Start Angle: Change which part of the ellipse is used to draw the arc
End Angle: Change which part of the ellipse is used to draw the arc
Position: Change the position of the arc's origin
Dimensions: Change the dimensions of the ellipse used to draw the arc
Max Angle Segment: Change the number of vertices used to draw the arc

This implementation draws an elliptical arc has the following style properties:

Line Width: Change the width of all of the arc's line segments
Line Color: Change the color of all of the arc's line segments
Line Stipple Pattern: Change the stipple pattern of all of the arc's line segments

A utility function is provided to allow arc generation given vertices - refer to setVertices for more info.
