GPS Visualizer does it by throwing an enormous white DIV (3x the size
of the map) over the entire map, by appending it to the
G_MAP_MAP_PANE. The opacity of that white screen is controlled with
CSS directives. For example:
var screen_opacity = 0.7;
theScreen.style.filter = "alpha(opacity="+screen_opacity*100+")";
theScreen.style.KhtmlOpacity = screen_opacity;
theScreen.style.MozOpacity = screen_opacity;
Then, every time the map is moved, the screen is repositioned to make
sure it still covers everything.
