Calculates a projected point from 2 known points and the X/Y offsets from point 1 using point1 and 2 to define the positive X axis.  The X/Y offsets can also be specified as the distance and a rotation angle if bRotation is set to TRUE

Note [!]

This will be interpreted as Rotation Angle or Y Coordinate depending on the bRotation parameter.
