Subject: New rule: interpret_move() is passed a pointer to the game_drawstate
X-Git-Url: https://git.distorted.org.uk/~mdw/sgt/puzzles/commitdiff_plain/e1f3c70792cacbc9f081f56294b132d9ffbd71f0?hp=e1f3c70792cacbc9f081f56294b132d9ffbd71f0

New rule: interpret_move() is passed a pointer to the game_drawstate
basically just so that it can divide mouse coordinates by the tile
size, but is definitely not expected to _write_ to it, and it hadn't
previously occurred to me that anyone might try. Therefore,
interpret_move() now gets a pointer to a _const_ game_drawstate
instead of a writable one.

All existing puzzles cope fine with this API change (as long as the
new const qualifier is also added to a couple of subfunctions to which
interpret_move delegates work), except for the just-committed Undead,
which somehow had ds->ascii and ui->ascii the wrong way round but is
otherwise unproblematic.
