Used by the routine at EnterRoom.
Sets the attributes of the side panel. The whole panel is filled with a colour that is picked from the attribute of the room, and then a shape and some bands of colour are put on top. ClearPlayArea_Row, which fills a block of cells with a value, does most of the work.
