in the Java build - which turns out to be a JVM bug in OpenJDK 6,
causing the NestedVM rendition of the expression (i==1?3:4) to be
mis-JITed. OpenJDK 7 appears not to do that any more, but this
equivalent (for these purposes) rephrasing should perturb the code
just enough to dodge the problem.

persisting between separate mouse actions. Revamp all uses of the
ndragcoords field in an attempt to stamp that out: we now distinguish
between active drags (>0), a valid click but no drag yet (0), and a
totally invalid situation in which all mouse activity will be ignored
until the next fresh attempt (-1).

line here' cross mark by dragging, and furthermore, that doing so puts
that grid edge into a stuck state that no UI action short of undo can
get it back out of. Fix drags to stop at crosses, and fix execute_move
to fault any move string that nonetheless somehow managed to try to
set a line over a cross without explicitly tagging it 'R'.

after return) to the callee (just before). Might print something
useful in the soak-test context (where that debug statement will now
be printed and previously wasn't), but the main aim is to remove the
variable 'ngen' at the main call site, which triggered a set-but-not-
used warning if the debug statement that printed it was compiled out.

in the 'unfinished' directory for a while, and has now been finished
up thanks to James Harvey putting in some effort and galvanising me to
put in the rest. This is 'Pearl', an implementation of Nikoli's 'Masyu'.
The code in Loopy that generates a random loop along grid edges to use
as the puzzle solution has been abstracted out into loopgen.[ch] so
that Pearl can use it for its puzzle solutions too. I've also
introduced a new utility module called 'tdq' (for 'to-do queue').
