Palisade: scale line thickness unboundedly with tile size.

The previous expression for WIDTH defined it, curiously, as (1 +
(TILESIZE >= 16) + (TILESIZE >= 32) + (TILESIZE >= 64)) which is
roughly logarithmic in tile size, but bounded above by a maximum of 4
pixels. On high-DPI displays this isn't really good enough any more.
Now I've set the line thickness to a constant fraction of the tile
size (but still bounded below by 1), so it's much easier to see the
lines when the puzzle is expanded to extra large size.
