Should the mapper `update()` methods be deprecated?
SingleCodimSingleGeomTypeMapper have an
update() method, which recomputes the internal state. That method dates from a long time ago, when
GridView objects had reference semantics. Nowadays,
GridView objects have value semantics, however; updating a mapper therefore requires telling it about the new
GridView. This is what @carsten.graeser implemented in !487 (merged).
This leaves the question of what to do with the old methods (
update without argument). Should they be deprecated? Or do they still serve a purpose?
