What is the point given by the x,y coordinate in SDL_EVENT_FINGER_MOTION?

The documentation essentially consists of “Normalized in the range 0…1”.

If there is only one finger down one would assume that it corresponds to the location of that finger within the window. True?

If there are multiple fingers down, then what is it? Is it the location of the finger whose ID is given in the event? Is it the centroid position of all the down fingers? Something else?

Location of the finger whose ID is given. If other touching fingers move, they will get their own events.

Thank you, @icculus.
