 * GALLERY BLOCK - portfolio grid, masonry, albums, carousel + lightbox.

 * Grid, masonry and album tiles are all .media-frame (components.css): a
 * clipped box that zooms its image on hover. This file only lays the tiles
 * out and styles the caption/album overlays. Carousel and lightbox markup
 * is driven by gallery.js and is unchanged.
