make taskswitcher preview reluctant to track far finger moves
the further up the finger in the gesture activation goes, the less direct the tracking is. here's how it looks like on my dev setup (to compare with master, the task preview tracks the finger 1:1, in the new the X tracking is still directly matching, but Y becomes more and more reluctant the further up it goes):
I think it feels a bit nicer, but I'm unsure if we want to go for this as it's technically just making rare cases a tiny touch nicer with the tradeoff of slightly more complexity. nothing about this is a necessary change to make the UX good. open for feedback.
