Subject: [PATCH] Let other constraints reconcile a partly fixed entity's free
 points

8) A moved entity that a Fixed holds only in part no longer pins its free
   points as hard anchors: they stay where the edit put them unless another
   constraint on the entity (e.g. Vertical) moves them, so the fixed point
   holds and the solve no longer fails when the two disagree.
