    For image test available in the demo, you are right, the zoom  
in/out buttons are not needed.

    That's thuth: less code, less potential bugs, easier maintenance.

    I included in the demo because the old snake demo had and the  
authors asked for the inclusion of those buttons. I think we should  
keep this feature because in the future other demos could demand the  
zoom in/out feature.
