Detailed Description

A PointRep class that draws a contour lines.

The ContourPointRep transforms a two dimension matrix of projected values into a set of colored contour levels. The algorithm used is adapted from CONREC, which is a contouring Fortran 77 subroutine written by Paul Bourke, of the Center for Astrophysics and Supercomputing, Swinburne University of Technology in Melbourne, Australia.

Bug:: Doesn't gray itself out when in deselected state.

Bug:: Does not respond to line style change.
