Come to think of it, the core of this bug might be outside of QtMir.
That is whatever eventually receives handleWheelEvent is failing to
scroll proportionately to the magnitude of angleDelta, and instead is
scrolling just proportionately to the number of calls to
handleWheelEvent.

Bug description:
Touchpad scrolling is disproportionately faster than mouse wheel
scrolling in Unity8 (web browser and system settings).
I can only say this with confidence today because I implemented
accurate smooth scrolling in Xmir yesterday, so I know how it should
behave.
It's possible QtMir is overreacting to the large number of events that
touchpads generate compared to a mouse wheel, without taking into
account the scroll magnitude of each one is smaller.
