    Fix error about setCapture not existing.
    
    element.setCapture only seems to exist in Firefox. On most other
    browsers, our attempt to call it must have been generating a whinge in
    the console log all along. But Ben's commit bb16b5a70ddf77d turned
    that into a prominent alert box, triggered on every mouse click in the
    puzzle canvas.
    
    Worked around by wrapping both calls to setCapture in a local
    subroutine which checks if it's there before calling it.
    
    Also, setCapture turns out to be deprecated in any case, according to
    https://developer.mozilla.org/en-US/docs/Web/API/Element/setCapture .
    It looks as if the non-deprecated version is element.setPointerCapture:
    https://developer.mozilla.org/en-US/docs/Web/API/Element/setPointerCapture
    But it also looks as if that needs the 'pointerId' field that's only
    found in 'onpointerdown' events and not 'onmousedown' ones. So
    including that as an alternative will be a bigger job.
