eb2013efc0 Cleanup: it was absolutely stupid for game_wants_statusbar() to be a
function, since it took no parameters by which to vary its decision,
and in any case it's hard to imagine a game which only
_conditionally_ wants a status bar. Changed it into a boolean data
field in the backend structure.

40fcf516f4 Cleanup: remove the game_state parameter to game_colours(). No game
was actually using it, and also it wasn't being called again for
different game states or different game parameters, so it would have
been a mistake to depend on anything in that game state. Games are
now expected to commit in advance to a single fixed list of all the
colours they will ever need, which was the case in practice already
and simplifies any later port to a colour-poor platform. Also this
change has removed a lot of unnecessary faff from midend_colours().

b7f192eea3 Cleanup: the `mouse_priorities' field in the back end has been a
more general-purpose flags word for some time now. Rename it to
`flags'.

af59dcf685 Substantial infrastructure upheaval. I've separated the drawing API
as seen by the back ends from the one implemented by the front end,
and shoved a piece of middleware (drawing.c) in between to permit
interchange of multiple kinds of the latter. I've also added a
number of functions to the drawing API to permit printing as well as
on-screen drawing, and retired print.py in favour of integrated
printing done by means of that API.

The immediate visible change is that print.py is dead, and each
puzzle now does its own printing: where you would previously have
typed `print.py solo 2x3', you now type `solo --print 2x3' and it
should work in much the same way.

Advantages of the new mechanism available right now:
 - Map is now printable, because the new print function can make use
   of the output from the existing game ID decoder rather than me
   having to replicate all those fiddly algorithms in Python.
 - the new print functions can cope with non-initial game states,
   which means each puzzle supporting --print also supports
   --with-solutions.
 - there's also a --scale option permitting users to adjust the size
   of the printed puzzles.

Advantages which will be available at some point:
 - the new API should permit me to implement native printing
   mechanisms on Windows and OS X.

c321a88408 Cleanups to completion flashes: all four of these games used to
redraw the whole window _every_ time game_redraw() was called during
a flash. Now they only redraw the whole window every time the
background colour actually changes. Thanks to James H for much of
the work.

414330d9ad Cleanups from James H: a few missing statics, a precautionary cast
or two, a debugging fix, a couple of explicit initialisations of
variables that were previously read uninitialised, and a fix for a
whopping great big memory leak in Slant owing to me having
completely forgotten to write free_game().

cc06b70328 The very core of cross() is capable of suffering integer overflow on
large puzzles. Resort to hand-hacked 64-bit arithmetic for doing dot
products; everything else remains in `long' for the moment.

(Ideally I'd auto-detect the presence of `long long' and use it in
place of my cheap plastic imitation where possible, but since I
currently don't have a configure mechanism that'll have to wait.)

3b5711c6a5 Another diagnostic mode for Untangle: if compiled with
`-DSHOW_CROSSINGS', it will show each edge in red if it is crossed
by anything, and in black otherwise. Distracting and not
particularly useful during play, but occasionally handy for
debugging cross().

bed038e17f The `Solve' operation now rotates and/or reflects the solution grid
to bring it as close as possible to the current game state. This
means that if you request `Solve' after solving a puzzle yourself,
with the intention of finding out how similar your solution is to
the program's, then you will mostly see the differences in _shape_
rather than those being masked by the fact that yours happened to be
the other way up.

1ff15ba8ad The Untangle completion flash was weedy and anaemic; beef it up a
bit. In particular, it now flashes between _two_ specially picked
colours (white and mid-grey), meaning that it should be visible even
if your default background colour is white; and it also flashes
twice rather than once.

0e68ad82a9 Switch Untangle to using long' rather than int' in its internal
rationals, for the sake of 16-bit-int platforms such as Palm. Thanks
to James H.

a8a903db47 New puzzle: `Untangle', cloned (with the addition of random grid
generation) from a simple but rather fun Flash game I saw this
morning.

Small infrastructure change for this puzzle: while most game
backends find the midend's assumption that Solve moves are never
animated to be a convenience absolving them of having to handle the
special case themselves, this one actually needs Solve to be
animated. Rather than break that convenience for the other puzzles,
I've introduced a flag bit (which I've shoved in mouse_priorities
for the moment, shamefully without changing its name).
