Comment the Mac build out of Buildscr, since I no longer have a
working Mac and hence can't build it any more.

Error checking in Pattern, which was until now the only remaining game
that _ought_ to have it but did not.

I've tried to implement it before and found that the most obvious
approach was so effective as to constitute a spoiler, so this is a
deliberately weakened approach which in a bit of play-testing seems to
be a more sensible balance. It won't necessarily tell you at the very
instant you put a foot wrong, but it will at least ensure that (my
usual minimum standard) once you've filled in the whole grid you will
either have seen a victory flash, or an error indicator showing you
why not.

Change some instances of 'print $thing' to 'print $thing || ""', to
prevent annoying Perl warnings when $thing is undefined.

Fix redundant redrawing in Pegs. Apparently it has always redrawn
every single peg and hole on the board, every time it did any kind of
redraw at all, because I forgot to update the array in the drawstate
indicating the last-drawn state of each position. And nobody's noticed
until now!

Add an explicit -lm to the link lines in Makefile.gtk, after two users
reported on the same day that this is now necessary since up-to-date
GNU tools won't consider it sufficient to have libm be a dependency of
other explicitly referenced libraries if you're directly referring to
the contents of libm yourself.

Increase by 1 in every direction the size of the blitter used to save
the background under a Guess coloured peg in mid-drag. Currently it
assumes the circle doesn't extend into the next pixel, which the docs
for draw_circle warn might happen due to antialiasing.

Swap a 'max' for a 'min', fixing an out-of-range colour component
being passed to the front end.

Increase by 1 pixel the clip rectangle used to draw and erase the
Black Box finish button. Like the Guess blitter, it was assuming
non-expansion of circles.

Typo fix from Helge Kreutzmann, forwarded from Debian.

Add a difficulty exception to prevent Pearl spinning forever when
asked to generate a 5x5 Tricky puzzle. (Debian bug #667963)

Permit users to reconfigure the default setting for each puzzle using
another of those hacky environment variables.
