What the pointer and the keyboard do on a drawing, on demand rather than printed under it.

The gestures are not obvious (a single click selects, a double click opens), so they have to be
somewhere; a paragraph under every drawing was the same sentences on every visit. `text` is the
whole of it, shown as the icon's tooltip and read out as its label.
