Add a Polygon to a Map

Adds a polygon to an existing map, by analogy to polygon(). Used by mapImage().

mapPolygon(
  longitude,
  latitude,
  density = NULL,
  angle = 45,
  border = NULL,
  col = NA,
  lty = par("lty"),
  ...,
  fillOddEven = FALSE
)

`longitude`	longitudes of points to be plotted, or an object from which longitude and latitude can be inferred (e.g. a coastline file, or the return value from `mapLocator()`), in which case the following two arguments are ignored.
`latitude`	latitudes of points to be plotted.
`density`	as for `polygon()`.
`angle`	as for `polygon()`.
`border`	as for `polygon()`.
`col`	as for `polygon()`.
`lty`	as for `polygon()`.
`...`	as for `polygon()`.
`fillOddEven`	as for `polygon()`.
