Module camera 

The scene camera (the game’s ticket 0228, moved here in 1154): a picture (a whole map, MapPicture) as a backdrop (game ADR-0048) behind a window of the console, panned by the pixel and zoomed in whole steps, with a caption and a text box over it. For checking by eye that a renderer keeps the scene sharp and seamless.

The game gives the picture, where the window and the box go, and what to say when it has no picture. The screen says what it shows as a SceneCameraView and glyph::paint_camera draws it.
