#126 Doubled mouse scroll events in terminal apps

[Travis Evans]

It seems that in terminal apps using the mouse, ROXTerm is sending each mouse wheel click event twice. I observe this in Ubuntu 16.04 with ROXTerm 3.3.2 and GTK3 3.18.9, and I also saw it in an (outdated) Arch Linux installation with ROXTerm 2.9.3/GTK 3.12.2. On both systems, GNOME Terminal, for instance, behaves as expected; only ROXTerm shows the behavior.

For example, I have tmux 2.1 set up to scroll half a page of history on wheel click, but in ROXTerm each click goes a full page. In a program that should increment or decrement a widget once per click, I always get increments of two in ROXTerm. In Weechat, I can actually see that each wheel click is getting acted on twice in a row in quick succession, with an extra window repaint in between. None of this happens in other terminals.

Most likely the same as bug #127.
