Letting go of the modifier key before the last momentum-scroll events arrive will cause the scroll direction to change. This problem can be seen by going to egui.rs and opening the "Scene" example. Hold down shift, start a momentum-scroll (on a Mac trackpad), then quickly let go of shift: you'll see the scroll direction change, which feels wrong. Store the modifiers at the start of the event, thanks to the new `phase` info added in * emilk#7669 Note that this solution only works on native; not on web. * Break out wheel/scroll handling into own file * Simplify it a lot by deciding late on wether an input is a scroll or a zoom * Assume input is already smooth if there are `phase` events

Problem
Letting go of the modifier key before the last momentum-scroll events arrive will cause the scroll direction to change. This problem can be seen by going to egui.rs and opening the "Scene" example. Hold down shift, start a momentum-scroll (on a Mac trackpad), then quickly let go of shift: you'll see the scroll direction change, which feels wrong.
Solution
Store the modifiers at the start of the event, thanks to the new
phaseinfo added inis_scrolling/is_smooth_scrollingutil, checking for active scroll action. #7669Note that this solution only works on native; not on web.
