I think the truth should be restored : there is no protocol issue.

In february this year, Ethan and I have patched gplt_x11.c to fix=20
klipper, the KDE clipboard utility, that was polling gnuplot for its=20
pixmap every second. Ethan wrote the patch to make gnuplot only respond=20
once to klipper. I wrote a patch to make gnuplot provide the TIMESTAMP=20
atom, because klipper would poll it instead of the pixmap and see that=20
the pixmap has not changed. TIMESTAMP is part of the ICCCM, so the=20
protocol is respected here. It's just that we were a little loosy=20
regarding TIMESTAMP, whereas klipper is expecting it to work properly. I=20
think Ethan's patch may be reverted without making the bug reappear if=20
it is too annoying to prevent multiple pastes of the same pixmap.

Then, there is this problem that Daniel has pointed out (*sometimes*=20
nothing is pasted), and again I don't think it is because of protocol=20
differences. It is probably a bug hidden somewhere in the timestamps=20
provided to the Xlib functions, or something like that.

And finally, as Daniel pointed out too, the X11 terminal only exports in=20
a "pixmap" form, and that's restrictive. Few apps can use it. But that's=20
not a bug, that's an improvement.

That's two bugs and one feature request. The first one is already=20
solved, the second one is not critical for 4.2 but can probably be=20
solved nicely, and as far as the last one is concerned, I am sure Daniel=20
is on the right path. Nothing to worry about.

What a nice name !! I love it !
