Should be the same under-the-hood but produces more
consistent code

a quick and dirty aspect ratio to the pinch-zoom handling

max amount of inputs in our Deque, we will still have our
first point stored (for pinching around a start-centroid mainly)

- Added a directTouch bool field to touch step function
- Some logic of how to gather accumulated zoom value

rather than doing it from the message pumping.

This produces less scattered timestamps as we now get the
timestamp from the touch monitor driver.
