introduces a few new utility functions in misc.c, one of which is
the bitmap obfuscator from Mines (which has therefore been moved out
of mines.c).

example, useful for games that wish to implement a user interface
which involves dragging an object around the playing area.

generator: (a) take out the `#ifdef SLOW_SYSTEM' because the new
generator is much more efficient, and (b) convert another int to
size_t to prevent the solver going negative in 16-bit ints as a
result.

sensible means of generating an initial gridful of rectangles. This
was previously a stupidly non-scalable bit of the Rectangles puzzle
generator: it filled a ludicrously large array with every possible
rectangle that could go anywhere in the grid, picked one at random
and winnowed the list by removing anything that overlapped that one,
then repeated until the list was empty (and therefore the grid was
full except for remaining singleton squares). Total cost was O(N^4)
in both time and space; not pretty.
Richard and Chris's sensible alternative was to place each rectangle
by randomly choosing a so-far-uncovered _square_, and then picking a
random rectangle from the possible ones covering that square. This
means we only have to deal with a small fragment of the rectangle
list at any one time, and we don't have to store the whole lot in
memory; so it's _much_ faster and more scalable, and has virtually
no memory cost.
A side effect of this algorithmic change is that the probability
distribution has altered. When you line up all the possible
_rectangles_ and pick one at random, then obviously the small ones
are going to be in the majority since lots of small ones can fit
into the space taken up by any given big one. So the original
algorithm tends to favour fiddly grids full of lots of tiny
rectangles, which don't tend to be very interesting. But if you
first pick a square and then think about the rectangles that can
surround that square, the small ones are suddenly going to be in the
_minority_ because there are only two ways you can place (say) a 2x1
containing a given square compared to 36 ways you can place a 6x6.
So this algorithm favours more large rectangles, which I generally
consider to be an improvement.

redrawn as non-black on undo. Introduce a new flag TILE_IMPOSSIBLE,
so that information about those black markers is cached in the
drawstate and we know when we have to erase them.
In the process I've removed the game_state argument completely from
the subfunction tile_redraw(), which gives me some confidence that
it isn't getting any _more_ privileged information out of it.

Windows for puzzles with status bars, because the initial call to
check_window_size is given the window size _without_ the status bar
and assumes that that has to be big enough for the whole thing
_with_ the status bar, so it shrinks everything by a little bit. So
now we resize the window to take account of the status bar before
calling check_window_size(), and the problem seems to have gone away.

(solving it only requires matrix inversion over GF(2), whereas
several of the other puzzles in this collection are NP-complete in
principle), but it's a fun enough thing to play with and is
non-trivial to do in your head - especially on the hardest preset.

symmetry which were not implemented in Solo. Now they are.
In the process I've completely retired symmetry_limit() on the
grounds that some of the new symmetries do not have a rectangular
base region; instead I determine the base region by going through
the grid and finding every square which is not transformed into a
lexicographically lower square by any symmetry operation. This means
that adding new symmetries is now _only_ a matter of encoding the
actual transformation rules.
[originally from svn r5965]
from saying `Auto-solved' or `Completed', the main function of the
status bar is to track the current size of a rectangle you're
dragging out, which makes life much easier when trying to count up
large rectangles in 19x19 mode.

gdk_font_from_description() will no longer even _try_ to return a
font matching the specified Pango font description; instead it will
return `fixed' no matter what you do. Therefore, I've had to switch
to using Pango proper for Puzzles text rendering, rather than just
using Pango for font selection.
[originally from svn r5936]
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.
[originally from svn r5911]
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.

it means something else as well. He sent this patch to switch Net

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.

a known solution or consult a solver. It simply indicates reasons
why (no superset of) the current grid would cause the completion

- 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)
- in Solo, arranged a means of sharing scratch space between calls
to nsolve to prevent a lot of redundant malloc/frees (gives a 10%
speed increase even on existing platforms)
