`VisADLineArray

[Stuart Wier <wier@xxxxxxxxxx>]

For a java package to extend the IDV I wish to make a subclass of the IDV's MetSymbol 
that draws a symbol in the z=0 plane that is filled and has more than 4 vertices. The 
existing IDV code makes symbols of (unfilled) lines using VisADLineArray, and filled 
symbols of of 3 and 4 vertices that using VisADTriangleArray and VisADQuadArray, and 
specifing the normals to each edge. See for example ucar.visad.ShapeUtility.java.  How 
are filled symbols of more than 4 vertices coded?  I need circles and ovals made from 
trig functions of angles.
