Class Description

This class represents a marker that offers a means of indicating a location on the map with an icon.

A marker consists of a geographic location and a visual representation in the form of a bitmap or a DOM element. Markers are rendered in screen space, that is although a marker is fixed to its geographic location, its icon is always rendered independently of the map's zoom level.
