An SPoly is a specialist graphic object that represents a polygon or polyline (multi-sided object or line).

ASSUMPTIONS
OpenMap assumes the following about polys:
- LatLon polygons should enclose an area less than one hemisphere.
- The vertices of the LatLon polygon should be specified in clockwise order. In some projections we deal with an ambiguous polygon by drawing the fill along the righthand side as we traverse the vertices in order, assuming a clockwise orientation.
- To be safe, never enclose extreme polar points within a LatLon polygon. Certain projections, (the cylindrical family including Mercator), cannot handle drawing these types of polygons. However it's ok to have a pole as a point along the edge of the poly. This isn't a restriction if you will be viewing the polygon using a good polar projection.
Not following these assumptions may result in unpredictable behavior!
Similar assumptions apply to the other vector graphics that we define: circles, ellipses, rects, lines.
