Arguments:
On Windows, this function returns true if and only if a mouse that has a wheel is installed. This function may be useful for an application that adds mouse-wheel methods to implement custom mouse-wheel behavior.
On GTK, nil is always returned because we
have not found a way to determine whether there is a mouse wheel.
