/* ============================================
   Window controls: minimize / maximize (js/shared/coursework-window.js)
   Minimize docks the window bottom-left - the minimized whiteboard and the
   Help button live bottom-right - and gives the page back. Maximize fills
   the screen. The close button joins the same row.
   The row is a slim bar that sticks to the top of the window. The window
   itself is what scrolls, so a close button placed absolutely scrolled away
   on a long paper, and it sat over the quiz timer in the top-right corner.
