Not a regression, but shuld go into emacs-24

[Jan Djärv]

Hello.

Jump-scrolling with Gtk+ scrollbars does not work with emacs 24 or 23.
Previously a left click on the through jumped one page forward or backwards.
A middle click on the through jumped to the place where the click was made.
A right click did nothing.

Or that was the intention.  It turns out that jumping probably never has 
worked with Gtk+.  The situation is now more pronounced as Gtk+ 3 at some 
point changed the meaning of
left click (previously page scroll, now jump)
middle click (previously jump, now does nothing)
and right click (previously did nothing, now does page scroll).

I would therefore like to commit this to the emacs-24 brach, even if the error 
is also present in emacs-23:
