API Vector3D CreateNormalVectorFromYawPitch

Constructs a unit vector in the given direction.
 vector = CreateNormalVectorFromYawPitch(yawRadians, pitchRadians)
== Arguments ==
; yawRadians : - Yaw about {0, 0, 1} going counter-clockwise from {1, 0, 0}.
; pitchRadians : - Pitch toward {0, 0, -1} from the nearest vector in the x,y plane.
== Returns ==
; vector : - Vector3DMixin in the given direction.
