/**
 * Simplifies a line string using an algorithm designed by Tim Schaub.
 * Coordinates are snapped to the nearest value in a virtual grid and
 * consecutive duplicate coordinates are discarded.  This effectively preserves
 * topology as the simplification of any subsection of a line string is
 * independent of the rest of the line string.  This means that, for examples,
 * the common edge between two polygons will be simplified to the same line
 * string independently in both polygons.  This implementation uses a single
 * pass over the coordinates and eliminates intermediate collinear points.
