When a wheel is in momenum mode and during each rotation update tick the wheel will reduce its current momentum value by this falloff percentage. The higher this value is the faster a wheel will slow down. The wheel is limited to integer math so the lowest this value can be is one.

LIB_EXPORT laResult laListWheelWidget_SetMomentumFalloffRate(
    laListWheelWidget* whl, 
    uint32_t rate
);
