Draw polygon. <Polygon>

• Draw a polygon whose corners at Longitude 135.2E-Latitude 35.4N, Longitude 135.4E-Latitude 35.6N, and Longitude 135.2E-Latitude 35.6N.

  The color can be specified in HEX (00-ff) in the order of Transparency, Blue, Green, and Red. For example, "ff0000ff" is opaque red.

  As the example for "Point", "Style" can be defined and used the style id in "styleUrl".

• Put the polygon at the altitude. <altitudeMode>

  As the example "Point", altitude relative to the ground can be specified by "<altitudeMode>relativeToGround</altitudeMode>"

• <name>, <TimeSpan>, <description>, <BalloonStyle> are same as "Point" example.
