A 2 dimensional vector with integer coordinates. Clear code will distinguish between situation where (x,y) is a location (ON_2iPoint) or a direction (ON_2iVector) and use the appropriate class.

default |
Default construction intentionally leaves x and y uninitialized. Use something like ON_2iVector pt(1,2); or ON_2iVector pt = ON_2iVector::Zero; when you need an initialized ON_2iVector.

For those times when a direction was incorrectly represented by a point. It is intentional that there is not an ON_2iVector constructor from an ON_2iPoint.
