Traditionally (and on most backends) there's a single master pointer driven by all pointing devices. The notable exception is Wayland though, where master pointing devices are created per capability in the case of pointer/touch, and one for each drawing tablet. This function call makes it easy to access all these. https://bugzilla.gnome.org/show_bug.cgi?id=790920
