Find the angle of a segment from (x1, y1) -> (x2, y2).
The difference between this method and Phaser.Math.Angle.Between is that this assumes the y coordinate travels down the screen.
The x coordinate of the first point.
The y coordinate of the first point.
The x coordinate of the second point.
The y coordinate of the second point.
