Zoom Video Allows zooming in video capture mode.

Introduction

The Canon A640 does not allow to zoom in videocapture mode. This script allows to zoom-in and zoom-out (8 steps) while in videocapture mode. The only problem is that the Canon A640/A630 only focuses when zooming finishes and not inbetween. This problem is not yet fixed.
