This example is used to confirm that resizable maps with multiple Google layers work properly. Click the checkboxes to add/remove layers from the maps. Use the layer switcher to change the map's base layer. You should be able to confirm the following:

1. Adding and removing layers doesn't raise any errors (regardless of how many times the same layer is added/removed).
2. The Google "Powered By" link is always visible and clickable when a Google layer is displayed.
3. The Google "Terms of Use" link is always visible and clickable when a Google layer is displayed.
4. Resizing a map (by resizing the browser window) and then changing base layer works well. That is, the center & scale are preserved and all tiles are well aligned.
5. Setting the base layer to the "Dummy Layer" hides all other Google base layers, "Powered By" link, and "Terms of Use" link.
