Look at http://maps.forum.nu//MInsetMapControl.js
This is a custom control that contains another GMap2 object, which has
no tiles.

The polygon is originally plotted in the custom control and when you
drag, you're actually dragging an entire invisible map which contains
the polygon.
When the center of the invisible map is (almost) equal to the center
of the main map, the polygon is transferred from the invisible map to
the main map.

This is not a generic, plug'n'play solution, but it demonstrates a
technique you can use to drag entire polygons.
To make polygons generally draggable with this technique you'll need
to transfer them back and forth between the two maps, and calculate
the difference between the two maps centers when the drag movement
ends.
