These values will be used for clickpad press and drag with two fingers.
While the clickpad button is not pressed, cumulative_d{x,y} will match x
and y values. Once the clickpad button is pressed, cumulative_d{x,y}
will be updated with the relative motion of each active touch on the
touchpad. This allows for dragging with one finger while another finger
stays stationary holding the clickpad button down.
This is an easier and less latent approach than trying to guess which
touch was the "dragging" touch.

Should this be wrapped in HAVE_MTDEV (or HAVE_MULTITOUCH)?
Probably. I forgot to test HAVE_MTDEV=0 and HAVE_MULTITOUCH=0 before
sending this patch set out, and I know there are issues. I plan to send
another patch set out soon with fixes for these issues.
Thanks,
