29 * This Presenter will display a card consisting of an image on the left side of the card followed
30 * by text on the right side. The image and text have equal width. The text will work like a info
31 * box, thus it will be hidden if the parent row is inactive. This behavior is unique to this card
32 * and requires a special focus handler.
