The other excellent feature of such demos is that they exercise parts
of the program that don't otherwise get a lot of coverage in testing.
The failure of "nibbles" on qt or wxt provided a convenient diagnostic
tool for identifying and repairing a fundamental limitation on our
mousing implementation.  So this week's gnuplot is that much better
than last weeks, and all because of nibbles :-)    
(which now, by the way, works fine on both qt and wxt).
