This is in preparation for receiving XI2 touch events. The version change is necessary as the events aren't sent at all otherwise.

This is the required version for XInput2 touch events. It also allows to greatly simplify the code by listening to master device events only and get rid of device id tracking:
Under XInput2 protocol version < 2.1, RawEvents are not supposed to be sent if a pointer grab is active. However slave device events are still received regardless of this specification and Wine implemented a workaround to receive RawEvents during pointer grabs by listening to these slave device events.
By advertising the support of XInput2 version >= 2.1, where RawEvents are sent even during pointer grabs, we ensure to receive the RawMotion even if a mouse grab is active. --- dlls/winex11.drv/mouse.c | 50 +++++++-------------------------------- dlls/winex11.drv/x11drv.h | 5 +--- 2 files changed, 9 insertions(+), 46 deletions(-)

Valuator names aren't well specified, and although they are usually named "Rel X/Y" or "Abs X/Y", there are cases where the names are different.
Lets just assume that the first two valuators are the X/Y axes, as it seems to be generally the case. --- dlls/winex11.drv/mouse.c | 21 ++++++++++----------- 1 file changed, 10 insertions(+), 11 deletions(-)
