Subject: [PATCH] From Cory Riddell, "The spherical manipulator uses a middle
 drag event for panning. It was panning for left-right drags, but was zooming
 for up-down drags. I changed it to pan both directions as I believe that is
 the correct behaviour. If the original combination pan-zoom behaviour was
 intentional, please let me know."
