mouse-wheel-present

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.
