various things:
- if you haven't fully understood what a game is about, it gives
you an immediate example of a puzzle plus its solution so you can
understand it
- in some games it's useful to compare your solution with the real
one and see where you made a mistake
- in the rearrangement games (Fifteen, Sixteen, Twiddle) it's handy
to be able to get your hands on a pristine grid quickly so you
can practise or experiment with manoeuvres on it
- it provides a good way of debugging the games if you think you've
encountered an unsolvable grid!

constructed at the same time as an internally generated game seed,
so that it can preserve any interesting information known by the
program at generation time but not physically contained within the
text of the game seed itself. (Such as, for example, the solution.)
Currently not used for anything yet, but it will be.

as text. This is used by front ends to implement copy-to-clipboard.
Currently the function does nothing (and is disabled) in every game
except Solo, but it's a start.

definitions, so let's move it so that it's just next to the
functions it relates to. This also opens the way for me to add more
booleans next to other functions without getting confused as to
which is which.

functions and a couple of variables, now each one exports a single
structure containing a load of function pointers and said variables.
This should make it easy to support platforms on which it's sensible
to compile all the puzzles into a single monolithic application. The
two existing platforms are still one-binary-per-game.

tiles randomly. (Rachel asked for this; it's been being tested for a good few
months now, and Simon didn't care either way, so in it goes :)
As part of this, the front end can now be asked to provide a random random
seed (IYSWIM).

argument `dir' which tells them whether this redraw is due to an undo, rather
than have them second-guess it from game state.
Note that none of the actual games yet take advantage of this; so it hasn't
been tested in anger (although it has been inspected by debugging).

parameters as a string, and decode it again. This is used in
midend.c to prepend the game parameters to the game seed, so that
copying out of the Specific box is sufficient to completely specify
the game you were playing.
Throughout development of these games I have referred to `seed'
internally, and `game ID' externally. Now there's a measurable
difference between them! :-)
[originally from svn r4231]
addition to the `game_state'. The new structure is intended to
contain ephemeral data pertaining to the game's user interface
rather than the actual game: things stored in the UI structure are
not restored in an Undo, for example.
make_move() is passed the UI to modify as it wishes; it is now
allowed to return the _same_ game_state it was passed, to indicate
that although no move has been made there has been a UI operation
requiring a redraw.

specifically, the elapsed time between calls varies much more with
GTK than it does under Windows. Therefore, I now take my own time
readings on every timer call, and this appears to have made the
animations run at closer to the same speed between platforms. Having
done that, I decided some of them were at the _wrong_ speed, and
fiddled with each game's timings as well.

is (a) pretty feeble, and (b) means that although Net seeds transfer
between platforms and still generate the same game, there's a
suspicious discrepancy in the typical seed _generated_ by each
platform.
I have a better RNG kicking around in this code base already, so
I'll just use it. Each midend has its own random_state, which it
passes to new_game_seed() as required. A handy consequence of this
is that initial seed data is now passed to midend_new(), which means
that new platform implementors are unlikely to forget to seed the
RNG because failure to do so causes a compile error!

mechanism I've just invented (the midend handles the standard game
selection configuration). Each game is now required to validate its
own seed data before attempting to base a game on it and potentially
confusing itself.
[originally from svn r4186]
taking non-zero time, which is triggered by the making of a move and
is _not_ hurried to its conclusion by the start of the next move (so
the game redraw function is expected to be able to draw it in
parallel with continuing moves). The only thing that prematurely
terminates a flash is the start of a fresh flash. In particular,
this concept is used to display the completion flash in Net, because
at least _my_ playing instincts make me lock every piece I've
unambiguously placed, and hence the last turn move is instantly
followed by a lock move which was previously suppressing the
completion flash.

are now expected to provide a list of `presets' (game_params plus a
name) which are selectable from the menu. This means I can play
both Octahedron and Cube without recompiling in between :-)
While I'm here, also enabled a Cygwin makefile, which Just Worked.
