    js: Add a CMake variable to control whether Emscripten emits WASM
    
    I've finally got bored of keeping (and occasionally losing) a patch
    that turns it off unconditionally.

    js: Very bad attempt at making puzzles change size when zooming
    
    This has the entertaining consequence that repeatedly zooming in and out
    causes puzzles to gradually shrink, thus demonstrating that recording
    the nominal size correctly will be necessary.

    js: Split setting nominal and actual canvas size
    
    Now zooming in and out repeatedly doesn't cause the canvas to wither
    away, but user resizes don't stick any more.  Still more to do.

    js: Distinguish manual resizes from device pixel ratio changes
    
    This adds a new callback, rescale_puzzle(), that's called when the
    device pixel ratio changes.  This means that resize_puzzle() can safely
    set the nominal canvas size, which means that manual resizing of the
    puzzle now sticks.
    
    Still missing: paying attention to the device pixel ratio when choosing
    the initial (or reset) size.

    js: Take device pixel ratio into account when setting default size
    
    This is a bit of a hack.  When setting the puzzle to its default size,
    either at startup or from a right-click on the resize handle, we now
    scale the default size from midend_size() by the device pixel ratio,
    and then pass that back to midend_size().  This does more or less the
    right thing, in that the puzzle now starts up at a size that scales
    with the font size.
    
    There are still some slight inconsistencies, where sequences of DPR
    changes and puzzle parameter changes can have order-dependent effects
    on the size of the puzzle.  Happily these effects are small and fairly
    hard to observe.
