On hover, horizontally expand the view area for each photo so users can see the whole thing.
Since we are currently relying on natural floats to position the elements, constantly changing the size of the containing box is becoming impractical.
The PhotoHFit function has to build all of the photos into individual "row divs" that we can more reliably control the expansion and contraction of, even when it expands beyond the current margins.
