- This will equal zero if the point C is on the line formed by
- points A and B, and will have a different sign depending on the
- side. Which side this is depends on the orientation of your (x,y)
- coordinates, but you can plug test values for A,B and C into this
- formula to determine whether negative values are to the left or to
- the right.
