[FYI] New controls for GStreetviewPanorama

[pamela fox]

In the next release, we are releasing a new UI for the controls in
GStreetviewPanorama. Instead of the two curved arrow buttons and the
zoom slider, the control will have a circle for panning, and just a
zoom in/zoom out button, both in the style of the new "3d" controls on
Google Maps.

You can see what that will look like here:

The API doesn't give programmatic access to the controls in
GStreetviewPanorama, so this should not affect your code. This may
affect the UI of your panoramas if they're small in size, however, as
this set of controls is slightly taller and wider than the last set.

If you have questions about this change, please ask in the forum.
