called `CURSOR_SELECT', intended for platforms which have a fire
button to go with their cursor keys. (Apparently some Palms do.)
CURSOR_SELECT is not bound to anything on any of the current three
platforms, and therefore no game may rely on it being available.
This checkin adds it in Net as a synonym for 'a', the keyboard-based
rotate-left command.

in terms of a constant TILE_SIZE (or equivalent). Here's a
surprisingly small patch which switches this constant into a
run-time variable.
The only observable behaviour change should be on Windows, which
physically does not permit the creation of windows larger than the
screen; if you try to create a puzzle (Net makes this plausible)
large enough to encounter this restriction, the Windows front end
should automatically re-adjust the puzzle's tile size so that it
does fit within the available space.
On GTK, I haven't done this, on the grounds that X _does_ permit
windows larger than the screen, and many X window managers already
provide the means to navigate around such a window. Gareth said he'd
rather navigate around a huge Net window than have it shrunk to fit
on one screen. I'm uncertain that this makes sense for all puzzles -
Pattern in particular strikes me as something that might be better
off shrunk to fit - so I may have to change policy later or make it
configurable.
On OS X, I also haven't done automatic shrinkage to fit on one
screen, largely because I didn't have the courage to address the
question of multiple monitors and what that means for the entire
concept :-)

of these recently) whose job is to update a game_ui to be consistent
with a new game_state. This is called by midend.c in every situation
where the current game_state changes _other_ than as a result of
make_move (Undo, Redo, Restart, Solve).
The introduction of this function allows a game_ui to contain
information about selections or highlights within a game_state which
simply wouldn't make sense when transferred to another game_state.
In particular, I've used it to fix a subtle bug in Solo whereby,
although you couldn't right-click to pencil-mode highlight a filled
square, you could _get_ a pencil-mode highlight in a filled square
if you used Undo and Redo. (Undo to before the square was filled,
right-click to highlight it, then Redo. Alternatively, left-click
and clear the square, right-click to highlight it, then Undo.)

their coordinates were outside the playing area. Clearly no actual
move should be made in that situation, but we do at least need to
sort out any highlighted squares from the prior dragging operations.

and positioned according to how many there are in the cell, rather
than how many distinct digits there are in the entire puzzle. This
means that 4x4 Solo can now be played with pencil marks without
_too_ much difficulty; the marks will still get a bit crowded if you
have more than 12 in the same square, but with luck that shouldn't
happen often, and as long as you're down in the 2-9 range things
should be entirely legible.

usefully be equivalent to right-clicking on platforms other than OS
X; in particular, it's useful if you're running Linux on Apple
hardware such as PowerBook which inherently has only one button. So
here's the fix for GTK, and Windows as well (the latter for
completeness and consistency, not because I can actually think of
any reason somebody might be running Windows on one-button
hardware).

mine density without (as you would with a conventional random grid
generator) rendering the game completely unplayable. High mine
densities are really good fun, and the point of the presets menu is
to provide people with pre-tested good settings and things they
might not have thought to try for themselves; so here are three
additional presets with high densities.

- fixed numerous memory leaks (not Palm-specific)
- corrected a couple of 32-bit-int assumptions (vital for Palm but
generally a good thing anyway)
- lifted a few function pointer types into explicit typedefs
(neutral for me but convenient for the source-munging Perl
scripts he uses to deal with Palm code segment rules)
- lifted a few function-level static arrays into global static
arrays (neutral for me but apparently works round a Palm tools
bug)
- a couple more presets in Rectangles (so that Palm, or any other
slow platform which can't handle the larger sizes easily, can
still have some variety available)

to nsolve to prevent a lot of redundant malloc/frees (gives a 10%
speed increase even on existing platforms)

- middle button now also triggers the clear-around-square action
- a special-case handler in midend_process_key() arranges that the
left button always trumps the right button if both are pressed
together, meaning that Windows Minesweeper players used to
pressing L+R to clear around a square should still be able to do
so without any strange behaviour.
(The latter touches all game backends, yet again, to add a field to
the game structure which is zero in everything except Mines.)

Rather than revealing the entire mine layout when you die, we now
only reveal the one mine that killed you. You can then Undo and
continue playing, without having spoiled the rest of the grid for
yourself. The number of times you've died is counted in the status
line (and is not reduced by Undo :-).
Amusingly, I think this in itself is quite a good way of dealing
with ambiguous sections in a Minesweeper grid: they no longer
_completely_ spoil your enjoyment of the game, because you can still
play the remainder of the grid even if you haven't got a completely
clean sweep. Just my luck that I should invent the idea when I've
already arranged for ambiguous sections to be absent :-)
[originally from svn r5886]
the Mines unique grid generator fails at high mine densities it is
_almost always_ for the same reason, and it also turns out that this
reason is one which can be addressed. So here's an enhancement to
mineperturb() which enables Mines to generate a grid at (as far as I
can tell) any mine density you like, up to and including w*h-9
mines. At densities of 1 in 2 or thereabouts the grids start to look
rather strange, but it can at least generate them without hanging.

function rather less uniform-looking than I'd intended. I _thought_
it looked a bit fishy, but had assumed it was just the human
tendency to see patterns where none exist. Now fixed, and some real
test vectors confirm that this time the obfuscation function is
actually what I intended it to be.
This means that all masked game IDs generated before this revision
are now invalid. That's a shame, but the game is only a day old and
I think I can reasonably justify it as teething trouble.

and it moves the polyhedron in the general direction of the mouse
pointer. (I had this in my initial throwaway Python implementation
of this game, but never reimplemented it in this version. It's
harder with triangles, but not too much harder.)
Since the logical-to-physical coordinate mapping in Cube is
dynamically computed, this has involved an interface change which
touches all puzzles: make_move() is now passed a pointer to the
game_drawstate, which it may of course completely ignore if it
wishes.

background colour for covered and uncovered squares in Mines, since
otherwise you have to distinguish them by the edge highlights alone.
So here one is; it's not _very_ different (it just looked odd if it
was any darker than this), but anyone who wants a bigger difference
can reconfigure it using the MINES_COLOUR_1 environment variable.

were already making sure that no shuffle move was the precise
inverse of the previous one, or contributed to repeating the
previous one so many times as to turn it into effectively fewer
moves (doing the same rotation three times in Twiddle, or shifting a
row by more than half its length in Sixteen). However, they were
only checking against the _last_ move, which meant that in any
situation where there were completely disjoint move spaces (4x4n2
Twiddle, or any Sixteen at all) it was still possible to have A then
B then inv(A) occurring in the shuffle, leading to an unnecessarily
easy game.
Now both shuffle routines keep separate track of all
_non-overlapping_ recent moves, and will avoid inverting any move
which hasn't had another move overlap it since it was made. This
should reduce the incidence of too-easy limited shuffle games,
although it can't be prevented _entirely_ (since, if nothing else,
it's always possible to increase the shuffle limit past the maximum
group radius).

indicates whether a particular game state should have the timer
going (for Mines the initial indeterminate state does not have this
property, and neither does a dead or won state); a midend function
that optionally (on request from the game) prepends a timer to the
front of the status bar text; some complicated midend timing code.
It's not great. It's ugly; it's probably slightly inaccurate; it's
got no provision for anyone but the game author decreeing whether a
game is timed or not. But Mines can't be taken seriously without a
timer, so it's a start.

blank grid until you make the first click; to ensure solubility, it
does not generate the mine layout until that click, and then ensures
it is solvable starting from that position.
This has involved three infrastructure changes:
- random.c now offers functions to encode and decode an entire
random_state as a string
- each puzzle's new_game() is now passed a pointer to the midend
itself, which most of them ignore
- there's a function in the midend which a game can call back to
_rewrite_ its current game description.
So Mines now has two entirely separate forms of game ID. One
contains the generation-time parameters (n and unique) plus an
encoding of a random_state; the other actually encodes the grid once
it's been generated, and also contains the initial click position.
When called with the latter, new_game() does plausibly normal stuff.
When called with the former, it notes down all the details and waits
until the first square is opened, and _then_ does the grid
generation and updates the game description in the midend. So if,
_after_ your first click, you decide you want to share this
particular puzzle with someone else, you can do that fine.
Also in this checkin, the mine layout is no longer _copied_ between
all the game_states on the undo chain. Instead, it's in a separate
structure and all game_states share a pointer to it - and the
structure is reference-counted to ensure deallocation.
