/** pmSourceContour()
 *
 * Find points in a contour for the given source at the given level. If type
 * is PM_CONTOUR_CRUDE, the contour is found by starting at the source peak,
 * running along each pixel row until the level is crossed, then interpolating to
 * the level coordinate for that row. This is done for each row, with the
 * starting point determined by the midpoint of the previous row, until the
 * starting point has a value below the contour level. The returned contour
 * consists of two vectors giving the x and y coordinates of the contour levels.
 * This function may be used as part of the model guess inputs.  Other contour
 * types may be specified in the future for more refined contours (TBD)
