I tried Ubuntu 12.04 that uses ancient libinput (or whatever it was back
then), which doesn't support MT. Mouse doesn't move at all with this
patch being applied. Without this patch mouse moves, but it's not usable
because the cursor's position is wrong, i.e. mouse position doesn't
match the screen touches.
This means that input_mt_report_pointer_emulation() doesn't set up
everything needed for the legacy pointer emulation.
