Magnifier inspection view for graphics cards

Cards are inspectable. While the magnifier inspection tray shows a card, a
mod-owned panel under the tray draws the card enlarged with its appearance
overlays and a turn-over button. No Harmony patches: a resident component
watches the inspection manager.
