- * - it ought to be possible to make the puzzle canvases resizable,
- * by superimposing some kind of draggable resize handle. Also I
- * quite like the idea of having a few buttons for standard sizes:
- * reset to default size, maximise to the browser window dimensions
- * (if we can find those out), and perhaps even go full-screen.
- *
* - I should think about whether these webified puzzles can support
* touchscreen-based tablet browsers (assuming there are any that
* can cope with the reasonably modern JS and run it fast enough to
* that using whatever they normally use to print PDFs!)
