Comment 1 for bug 1840501

@Matt, unfortunately it returns the anchor position of the module. It looks like someone forgot to override this in the MODULE object to return the geometrical center of the footprint which is what MODULE.GetFootprintRect().Centre() does. Technically you are correct but I'm reluctant to change this for fear of breaking something due to MODULE::GetCenter() being used incorrectly somewhere else withing KiCad.
