    hat-test: support SVG output.
    
    I want to generate an SVG diagram for an upcoming article.

    Add a 'core' library alongside 'common'.
    
    The 'core' library contains almost all the same objects as 'common',
    but leaves out hat.c. And the auxiliary program 'hatgen' now links
    against that slightly reduced core library instead of 'common'.
    
    This avoids a dependency loop: one of hatgen's jobs is to generate
    hat-tables.h, but hat-tables.h is a dependency of it.
    
    Of course, the generated hat-tables.h is already committed, so this
    doesn't present a bootstrapping problem in a normal build. But if
    someone modifies hatgen.c in order to regenerate hat-tables.h, and
    does so in a way that makes it uncompilable, they can't rebuild hatgen
    and try again! Of course you can always revert changes with git, but
    it's annoying to have to. Better to keep the dependencies non-cyclic
    in the first place.

    Fix some unused-variable warnings.
    
    A test-build with a modern clang points out a number of 'set but not
    used' variables, which clang seems to have got better at recently.
    
    In cases where there's conditioned-out or commented-out code using the
    variable, I've left it in and added a warning-suppressing cast to
    void. Otherwise I've just deleted the variables.

    Loopy / grid.c: support the new Spectre monotiling.
    
    This uses a tile shape very similar to the hat, but the tiling
    _structure_ is totally changed so that there aren't any reflected
    copies of the tile.
    
    I'm not sure how much difference this makes to gameplay: the two
    tilings are very similar for Loopy purposes. But the code was fun to
    write, and I think the Spectre shape is noticeably prettier, so I'm
    adding this to the collection anyway.
    
    The test programs also generate a pile of SVG images used in the
    companion article on my website.
