This prevents multiple scroll events happening for wayland compositors
which send axis values other than 10. For example, libinput will
typically return 15 for each scroll wheel step, and if a wayland
compositor sends those to xwayland without normalising them, 2 scroll
wheel steps will end up as 3 xorg scroll events. By listening for the
discrete_axis event, this will now correctly send only 2 xorg scroll
events.
The wayland protocol gurantees that there will always be an axis event
following an axis_discrete event. However, it does not gurantee that
other events (including other axis_discrete+axis pairs) will not happen
in between them. So we must keep a list of outstanding axis_discrete
events.

X Server The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into. Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders. For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server All questions regarding this software should be directed at the Xorg mailing list: https://lists.freedesktop.org/mailman/listinfo/xorg Please submit bug reports to the Xorg bugzilla: https://bugs.freedesktop.org/enter_bug.cgi?product=xorg The master development code repository can be found at: git://anongit.freedesktop.org/git/xorg/xserver https://cgit.freedesktop.org/xorg/xserver For patch submission instructions, see: https://www.x.org/wiki/Development/Documentation/SubmittingPatches For more information on the git code manager, see: https://wiki.x.org/wiki/GitPage As with other projects hosted on freedesktop.org, X.Org follows its Code of Conduct, based on the Contributor Covenant.
