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