coordinate-rounding, causing picking up arrows from a dot anywhere
other than at the centre of a square to break.

adequately hard one couldn't be found, but we must never return a
puzzle harder than the user asked for, and we _certainly_ mustn't
return one that we aren't even sure has a unique solution.
However, when I attempted to implement this rule, it turned out that
an attempt to generate a 15x15 Easy puzzle didn't terminate before I
got bored and killed it. I'm therefore retiring the Easy difficulty
level on the grounds that it's not a wide enough band to be useful.
I've renamed Hard to Normal, and (while I was there) renamed
Recursive to Unreasonable in line with my normal practice.

infrastructure to the mkfiles.pl framework for the convenience of
the build script: it generates `wingames.lst', a list of the Windows
binaries which are ship-worthy games as opposed to nullgame or
command-line auxiliary programs.

zero as a valid puzzle symbol, it can support at most 35 symbols,
not 36. (This is largely academic since IME anything above about 25
is impractical to generate, but there we go.)

Kevin Lyles spotted a tree234 bug! copytree234() segfaulted when
asked to copy a tree containing no elements, due to failing to allow
for the case that t->root might be NULL. Fixed, and added a
regression test.

supports monochrome icons, can deal with any size of image you're
mad enough to put in there, and will construct icons with whatever
combination of sizes and resolutions you feel like specifying. This
has involved a change in the command-line syntax, hence the
adjustment to Makefile.
(I don't imagine that the changes described here will be critical to
Puzzles any time soon, but I might reuse this script elsewhere and
then I won't want it to have arbitrary limitations.)

instead of having the puzzle binary export its window ID to a script
which then runs xwd, we can use the gdk-pixbuf library to have the
puzzle binary _itself_ read its own internal pixmap and save it
straight to a PNG. How handy. And faster, and less timing-sensitive.

mkfiles.pl change (I don't seem to be planning ahead very well this
week), this time to provide a list of fallback options for an object
file. That way, I have a no-icon.c which quietly replaces
icons/foo-icon.c if the latter doesn't exist, and so again people
checking straight out from Subversion shouldn't have trouble.

Windows puzzle binaries. This checkin involves several distinct
changes:
- mkfiles.pl now has an extra feature: if an object file is listed
in Recipe with a trailing question mark, it will be considered
optional, and silently dropped from the makefile if its primary
source file isn't present at the time mkfiles.pl runs. This means
people who check out the puzzles from Subversion and just run
mkfiles.pl shouldn't get build failures; they just won't get the
icons.
- all the .R files now use this feature to include an optional
Windows resource file.
- the .rc resource source files are built by icons/Makefile.
- windows.c finds the icon if present and uses it in place of the
standard Windows application icon.
