pub fn post_horizontal_scroll(delta: i32)Expand description
Synthesise a horizontal scroll of delta wheel lines at the current focus.
Used by the gesture/thumbwheel capture watcher to re-inject the MX thumb
wheel’s scrolling after the wheel has been diverted over HID++ to capture its
click. delta is the device’s raw rotation; its sign follows the wheel’s
rotation convention and its magnitude (one line per rotation increment) may
need tuning per device, since the diverted resolution differs from native.
No-op (logs nothing) on platforms without CGEvent.
