Soft-breaking Changes

Changes that may break existing code whose fixing is trivial:

• change object.points() to object.points everywhere.
• change object.cell_centers to object.cell_centers().points everywhere.
• change Picture() to Image() everywhere.

Hard-breaking Changes

Changes that will break existing code and need active thinking and some work to adapt

• None
