That worked brilliantly and I now have a test-case of a 1000-piece puzzle
with about 800 pieces solved.  No need for a script ... just one "line editor"
command in vi, :202,$ s/=.*$/=<X from line 201> <Y from line 201>/

The slowness in fitting one piece is reproducible, as is a simpler case of
slowness when just trying to drag the 800-odd pieces in the solved part.

I will investigate the problem in more detail over the next week or two,
putting timing and debug messages in Palapeli or QGV, as required.

Christmas time in Australia is also the beginning of the summer holiday
season, so I will fit Palapeli work in when I can.  However I think if I can
nail it down to a simple test-case it will be sufficient to solve the problem
(wherever it lies) in time for KDE 4.5, when Palapeli starts to provide more
support for large puzzles.  It would be nice to solve it in 4.4, but ... :-)

I will keep you posted.  Cheers, Ian W.
