Pivoting my finger around the tip but not getting appropriate precise cursor
movement

With the patch from https://bugs.freedesktop.org/show_bug.cgi?id=90735,
trackpad cursor movement is much improved for fast and medium-speed movements.
But it's still sluggish and imprecise for very slow movements. To move the
cursor 5-10 pixels should ideally be accomplishable with very subtle, precise
finger movement--such as pivoting your finger around the very tip without
actually moving the tip. Pivoting your finger like this right now generally
results in no cursor movement at all, or jerky, erratic movement.

I've attached an evemu recording of me pivoting my finger around its tip,
expecting to get very precise cursor movement, but instead getting either
nothing, or erratic, jerky movements.
