The functionality for zooming was removed from SVG during the
Candidate Recommendation period due to implementation feedback.
There is only magnification now, so there should be no
mention of zooming.

If the internal version of the specification still mentions
zooming here, we'll make sure it is removed.

Thanks for the feedback.
