Help with GMAP sample application

[Siki Zoltan]

Hi Nelson,

These variables are generated by the form. keymap and mainmap are input 
image form items. When you click on the map or the overview map your 
browser adds _x _y variables to the query string with the pixel 
coordinates of the position of the click.
