How do I pan and zoom in an image?

Spare5 recently changed our tools for bounding box and cuboid tasks.

The big change: we removed the Draw and Select tools. Draw and Select are now always on.

To move or "pan" around in an image: you now hold down the [Space] bar.

Zooming in and out still is the same: press the Zoom In and Zoom Out buttons, or use Ctrl-Plus and Ctrl-Minus.
