Fix sub pixel raw motion

I had the issue on the Witcher 3, getting slow mouse movement unregistered and
hitting seemingly random "walls".
I found it came from wine receiving "fractions"/"sub-pixel" mouse motion
(motion >0.0 but <1.0). The cause is probably my high dpi mouse that I setup
with 'libinput Accel Speed' to "-0.5" (same as xorg.conf "AccelSpeed").

I made this patch on wine-3.14: it accumulates those "sub-pixel" motion and
sends to windows when there is a "full pixels" motions (because it does not
handle fractions; movements <1.0 are truncated to 0, so ignored).

This is my first patch, so probably not perfect.

Also, this bug could be related and fixed with the patch:
