WINEDEBUG=+cursor,+win wine minetest.exe | trimmed to one repetition of the
bugged SetCursorPos call

Discovered by testing Minetest 5.9.0 [1] in Wine. In-game, the cursor is always
moved to the center. However, when the xinput "Coordinate Transformation
Matrix" parameter, the cursor moves to unpredictable positions (bottom right
corner, for example). The game becomes unplayable.

I think it's caused by "X11DRV_SetCursorPos" because skipping
"NtUserSetCursorPos" entirely does avoid this issue. The cursor position is no
longer centred, but the game does not look as glitchy any more.

System specifications:

* Ubuntu 22.04, X11, xfce4
* amdgpu driver

Reproduced in Wine 9.1, Wine 9.17 and Proton 9.0-2.

Reproduced with

* Wine's virtual desktop on and off
* Window manager decorations on and off (winecfg)
* Window manager control on and off (winecfg)

Steps to reproduce:

1. xinput list
2. Remember the xinput <ID> of the mouse (Virtual core pointer -> HID)
3. xinput --set-prop <ID> 'Coordinate Transformation Matrix' 1.1 0 0 0 1.1 0 0
0 1
4. Join a world in Minetest and try to play

This problem does not occur when the Transformation Matrix is set to "1.0 0 0 0
1.0 0 0 0 1". It also does not occur on Windows due to lack of xinput and X11
in the first place.
