The `google-map-point` element represents a point on a map. It's used as a child of other
google-map-* elements.

<b>Example</b>—points defining a semi-translucent blue triangle:

    <google-map latitude="37.77493" longitude="-122.41942">
      <google-map-poly closed fill-color="blue" fill-opacity=".5">
        <google-map-point latitude="36.77493" longitude="-121.41942"></google-map-point>
        <google-map-point latitude="38.77493" longitude="-122.41942"></google-map-point>
        <google-map-point latitude="36.77493" longitude="-123.41942"></google-map-point>
