Calculates the squared distance from a point to a box when projected to 2D.

The input rectangle is assumed to be on the XZ plane, and to actually represent an infinitely tall box (along the Y axis).

The planeProjection matrix projects points from 3D to 2D. The box will also be projected. The upProjNormalized vector is the normalized direction orthogonal to the 2D projection. It is the direction pointing out of the plane from the projection's point of view.

In the special case that the projection just projects 3D coordinates onto the XZ plane, this is equivalent to the distance from a point to a rectangle in 2D.
