buttons in several games if STYLUS_BASED is defined: in games where
you can set a puzzle element to 'on', 'off' or 'not yet set', when
it's hard to mimic a second mouse button, it's better to have the
one 'button' cycle between all three states rather than from 'on'
back to 'unset'.

Loopy mark LINE_NO grid edges with very faint lines, instead of
leaving them totally undrawn. Helps in complex grid types where the
line layout isn't entirely obvious to a player not already familiar
with it. Disableable by setting LOOPY_FAINT_LINES=n in the
environment, just in case anyone turns out to seriously dislike it.
(You could probably disable it via LOOPY_COLOUR_6 too, but you'd
have to know the exact shade of your background to get that right.)

people have generally seemed to think Loopy is one of the more
difficult puzzles in the collection. There's a new level called
Tricky, between Normal and Hard, which is equivalent to the old
Normal.

doesn't have diagnostics embedded and the ASCII formatter can't
print non-square puzzles anyway; but it can grade difficulty, which
is what I most immediately want it for.

particular, Great Hexagonal tilings previously had virtually every
(if not _actually_ every) hexagon on the inside of the path, and now
don't.

spins forever, but observes that raising the limit to 4x4 across all
grid types is not good for the complex grids like great-hexagonal.
Introduce per-grid minimum sizes using mad macro trickery.
(In fact, for each grid type I've put in a minimum size which _both_
dimensions must equal or exceed, plus another minimum size which _at
least one_ must equal or exceed; that permits both 3x4 and 4x3 Cairo
while disallowing 3x3.)

on Windows at all?! Fix some departures from the C standard, mostly
declaring variables after a statement has already been issued in the
same block. MSVC is picky about this where gcc is forgiving, and TBH
I'd change the latter given the choice.

Lambrou. Now capable of handling triangular and hexagonal grids as
well as square ones, and then a number of semiregular plane tilings
and duals of semiregular ones. In fact, most of the solver code
supports an _arbitrary_ planar graph (well, provided both the graph
and its dual have no self-edges), so it could easily be extended
further with only a little more effort.

_conditionally_ able to format the current puzzle as text to be sent
to the clipboard. For instance, if a game were to support playing on
a square grid and on other kinds of grid such as hexagonal, then it
might reasonably feel that only the former could be sensibly
rendered in ASCII art; so it can now arrange for the "Copy" menu
item to be greyed out depending on the game_params.
To do this I've introduced a new backend function
(can_format_as_text_now()), and renamed the existing static backend
field "can_format_as_text" to "can_format_as_text_ever". The latter
will cause compile errors for anyone maintaining a third-party front
end; if any such person is reading this, I apologise to them for the
inconvenience, but I did do it deliberately so that they'd know to
update their front end.
As yet, no checked-in game actually uses this feature; all current
games can still either copy always or copy never.

as `signed char' or it will break on platforms whose default char is
unsigned.

is mostly done with ifdefs in windows.c; so mkfiles.pl generates a
new makefile (Makefile.wce) and Recipe enables it, but it's hardly
any different from Makefile.vc apart from a few definitions at the
top of the files.
Currently the PocketPC build is not enabled in the build script, but
with any luck I'll be able to do so reasonably soon.

checks. He thinks they were harmless (due to being followed by other
range checks in RIGHTOF_DOT and friends) but it clearly can't hurt
to fix them anyway.

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.
[originally from svn r6417]
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().

game_print(), wherever feasible. This fixes a specific bug in Loopy
(James H's new field ds->linewidth wasn't being set up, leading to
corrupted print output), but I've made the change in all affected
files because it also seems like a generally good idea to encourage
it for future games, to prevent other problems of this type.
There is one slight snag, which is that Map _can't_ do this because
its game_set_size() also initialises a blitter. I could fix this by
abstracting the common parts of Map's game_set_size() out into a
subfunction called by game_set_size() and also called directly by
game_print(); alternatively, I could introduce a means of
determining whether a `drawing *' was for screen or printing use.
Not sure which yet.

goes round the main loop, in favour of the usual type of
`done_something' flag.

- remove the backtracking `Hard' level, on the grounds that it was
incredibly slow and not really usable.
- introduce an `Easy' difficulty level below the standard one; many
people seem to find this puzzle unusually hard, so an easy level
is particularly helpful.
- highlight unfulfillable clue squares (but not yet any other types
of obvious error).
