Our support for polar polygons leaves a lot to be desired. Drawing or loading a polygon near (but not necessarily containing) the pole can result in unexpected behavior.

3D (note artifacts):

The artifacts come from how the polygon is represented in 2D, which is visualized like so:

Even more regular polygons which do not produce artifacts

still have issues with their 2D representation:

These polygons should have both the correct 2D representation (to be properly queried against the spatial index and against remote servers) and the correct 3D display.

feat: add polar polygon support
7a68bc7 
Adds support for polar polygons by splitting them by the meridian

plane for display/query in 2D. Additionally, queries for OGC servers

such as GeoServer are now split over the antimeridian in the event

that the remote server does not allow coordinates outside of the

longitudes [-180, 180].

resolves ngageoint#540, ngageoint#579
