This is the direction that the object is facing. This has little effect unless the object’s icon is directional. In the case of a directional icon, this selects the corresponding orientation from the icon file.
An icon file with only four (cardinal) directions makes the choice of orientation ambiguous when the true direction is a diagonal. In that case, of the two possibilities, the one closest to the previous orientation is displayed. Sounds complicated, but it’s what one would naturally expect.
