Bug#714399: a7xpg: spaceship drifts to upper left corner of screen making gameplay impossible

[Jason Quinn]

You are right, Peter! I ran jstest-gtk and my mouse is being detected
as a joystick! I quickly tried the game with and without my mouse and
this toggles the problem. It is a Microsoft Wireless Mobile Mouse 4000
(Model 1383). I happen to have TWO of the same mice and I tested both
and they both exhibit the same problem. I then tried calibrating the
mouse using jstest-gtk but I still cannot get the mouse to work.

jstest-gtk detects both mice as "Microsoft Microsoft® Nano
Transceiver v1.0" and as "Device: /dev/input/js0" with "Axes: 37" and
"Buttons:57". ALL the axes are shown in the jstest-gtk information
window show with value -32767 except for Axis 10 and 11 which are 0.

It becomes a question now whether the mouse is sending invalid output
and/or the game is not processing valid input.

Cheers,
Jason
