Documentation error

Just a documentation error:

Inside VirtualJoystickEvent<S>:

    /// Delta value ranging from 0 to 1 in each vector (x and y)
    pub fn axis(&self) -> Vec2 {
        self.delta
    }

I thought from the documentation for x-axis 0 was all the way to the left, and 1 is all the way to right right.
But for the x-axis -1 is left and +1 is right. Similar for y-axis.

Maybe it should say:
/// Delta value ranging from -1 to 1 in each vector (x and y)

Please change label to enhancement. I clicked the wrong one, sorry.
