Peter Hutterer af88b43f9e dix: don't emulate scroll events for non-existing axes (#47281) 
Test case:
- create a device with REL_HWHEEL and ABS_X and ABS_Y. evdev 2.7.0 will set
  that up as device with 1 relative axis
- move pointer to VGA1
- xrandr --output VGA1 --off

Warps the pointer to the new spot and calls GPE with the x/y mask bits set.
When running through the loop to check for scroll event, this overruns the
axes and may try to emulate scroll events based on random garbage in the
memory. If that memory contained non-zero for the scroll type but near-zero
for the increment field, the server would hang in an infinite loop.

This was the trigger for this suggested, never-merged, patch here:

					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:
http://en.wikipedia.org/wiki/X_server

All questions regarding this software should be directed at the
Xorg mailing list:
