gtk,scrolledwindow: Rework physics behind kinetic scrolling

Browse Source

The maths being used didn't resemble much about velocities or
friction/deceleration, so reimplement it in terms of velocity
vectors and decelerations, measured in pixels/ms^2.

Overshooting is also handled within the deceleration effect,
turning into a constant acceleration vector in the opposite
direction so it returns elastically within the boundaries.
