// Version 0.2      the .copy() parameters were wrong
// version 1.0      added .show() .hide() .setContents() .setPoint() .setOpacity() .overlap
// version 1.1      Works with GMarkerManager in v2.67, v2.68, v2.69, v2.70 and v2.71
// version 1.2      Works with GMarkerManager in v2.72, v2.73, v2.74 and v2.75
// version 1.3      add .isHidden()
// version 1.4      permit .hide and .show to be used before addOverlay()
// version 1.5      fix positioning bug while label is hidden
// version 1.6      added .supportsHide()
