The rationale was:
This tells which events get delivered to the window while grabbing. XWayland
might be sensitive to `GDK_TOUCH_MASK` while Xorg is not.
So the Idea was to keep the current way (with `gdk_pointer_grab` or
`gdk_device_grab`, and adding the "deliver TOUCH events to me" might fix it.
Another place to investigate is:
#define GDK_FILTERED_EVENTS_MASK static_cast<GdkEventMask>(GDK_ALL_EVENTS_MASK \
& ~GDK_TOUCH_MASK)
It seems that Xorg converts touch events to regular mouse events, but XWayland
might be different.
