Issue description

An expression in a linked view is not updated when the base view position is changed.

X,Y properties are set to Prop_Output to avoid extra recompute of geometry when the position of the view changes. This means that X,Y changes in the base view do not trigger a recalculation of the expression in the linked view.

X,Y were changed to Prop_NoRecompute, but this causes excessive updating of geometry in Sections and Details, and so the change was reverted.

The linked view needs to know that the change triggering the recalculation is only for position and that the geometry does not need to be recomputed.

Anything else?
