- Scroll paning (`shift + scroll`) is now synced for the keyframe viewport, easing viewport and scrollbar (Closes#22)
- Scroll zooming out (`ctrl + scroll down`) is now bounded to avoid zooming out to infinity (Closes#19)
There is still some quirky behaviour when using scroll to zoom inwards. It does not seem to respect the `pivotPointInUnitSpace` correctly. I've tried fixing it, but I've hit a dead end.
