A geometry represents a shape that can be drawn in a vector layer. > Is it closer in spirit to a LonLat or a Pixel? A lonlat, as a lonlat and a point both represent a geographic location. A lonlat isn't a shape and cannot be drawn. A pixel represents a position in the map div, its x and y values are expressed in pixels. A Map object exposes method for converting a pixel to a lonlat and vice-versa. >Why does its constructor take x and y rather than a LonLat or Pixel? OpenLayers could indeed include a Geometry.Point.fromLonlat conveniene function or something, but it currently doesn't have such a function.
