Describe the bug

The Fyne scroll accelerate logic - where scrolling above a certain input speed has a multiplicative factor applied to it to create an accelerated scrolling rate, causes poor UX with scrolling where it suddenly "jumps" to a faster scroll rate leading to a perception of "unsmoothness".

See github.com/dweymouth/supersonic/issues/418

A potential solution would be to apply a smooth function to gradually increase effective scroll rate based on input scroll rate, or disable the scroll accelerate logic for MacOS if the OS already handles it at the driver level.

How to reproduce

Run fyne demo - scroll the grid wrap at varying speeds

A little testing suggests that scroll acceleration may not be needed at all on MacOS since the OS seems to apply its own scroll acceleration curve already
