/* ============================================================
   活用 TV (the Conjugator) and Rewind (the Deconjugator).

   The page is a photograph of a room with an old CRT television, and the
   question is drawn onto the TV's screen. Everything about where the screen
   is comes from a handful of numbers — the screen's position in the photo as
   fractions of its width and height — so the overlay stays on the glass at
   any window size:

     --sx --sy --sw --sh   the screen, as fractions of the photo
     --cx                  the TV's centre, used when the photo is zoomed in
     --vx --vy             the VCR's display
     --p                   which part of the photo stays when it is trimmed
                           top and bottom (0 = keep the top, 1 = keep the bottom)

   The answer box, the buttons, the feedback and the settings sit under the
   TV, like a remote on the table.
