Pedro J. Estébanez 9692549c34 Track screen drag speed
Following the universal input handling effort, this works the same for every platform, as long as the touch move event coming from it contains the relative movement.

The same tracking algorithm used to track the mouse speed is used here, but tracking separately each touch index.

Fixes #3623.
