    Hats tiling: more uniform parent selection.
    
    This tweak improves the uniformity of the generated patches of hat
    tiling, by selecting from (the closest 32-bit approximation I can get
    to) the limiting probability distribution of finite patches in the
    whole plane.
    
    This shouldn't invalidate any grid description that contains enough
    coordinates to uniquely specify a piece of tiling - in particular, any
    generated by the game itself. But if anyone's been brave enough to
    hand-type a grid description in the last two days and left off some of
    the coordinates, then those might be invalidated.

    Hats tiling: make hat-test draw each hat in one go.
    
    By introducing a second callback between the client of hat.c and the
    maybe_report_hat function, I enable the test main() to provide a
    different version of that callback, so that instead of enumerating
    each kite, it can directly generate a Postscript path per actual hat.
    This should make it more useful to people wanting to generate hat
    patterns for any other purpose.
    
    The internal callback gets more details than the external one; in
    particular, it receives a HatCoords, so that it can colour hats based
    on their position in the hierarchical structure.

    hat-test: allow specifying tiling size on the command line.
    
    I'm tired of recompiling every time I want a different size of test
    patch.

    hat-test: alternative data output mode to write Python.
    
    This mode emits a sequence of calls to an imaginary Python function.
    Should be useful to anyone wanting to post-process the tiling in any
    way.

    Loopy: widen clip rectangle for redrawing clues.
    
    The new Hats tiling generates a lot of clues that are 2-digit numbers.
    At large puzzle sizes, the previous clip rectangle didn't quite
    include the ends of such a number, meaning that if the number had to
    be redrawn in red to highlight an error, the leftmost and rightmost
    parts of the text would remain black.
