getPosition

Get the Position property. Position of the light source relative to lit (extruded) geometries, in [r radial coordinate, a azimuthal angle, p polar angle] where r indicates the distance from the center of the base of an object to its light, a indicates the position of the light relative to 0° (0° when `light.anchor` is set to `viewport` corresponds to the top of the viewport, or 0° when `light.anchor` is set to `map` corresponds to due north, and degrees proceed clockwise), and p indicates the height of the light (from 0°, directly above, to 180°, directly below).
