System-wide iPad gestures produce a click event on activation about osu-framework HOT 3 OPEN

This does do the exact same thing for me.

Since SDL is used for input handling on iOS, and SDL_TouchFingerEvent doesn't seem to have a notion of canceling an event. This should be reported first to upstream, preferably with verbose SDL_HINT_EVENT_LOGGING enabled.

I know that Android has a similar notion of canceling motion events. And the same thing could apply to desktop: the window loosing focus when a mouse button is held (via alt-tab or another app coming to the foreground).

Not sure what's the best way to implement in o!f. On a high level, if a touch up input is cancelled, it shouldn't fire a ClickEvent. The touch/mouse up event should still fire so it doesn't get stuck in a down state.

A good start would be to implement a "Cancelled" state to button input events, which "MouseButtonEventManager" uses as an indicator to not fire a click event while still firing a mouse up event.

That would also replace an existing flag in that class that works similarly (used in hold-for-right-click logic).
