Usage notes
- Use this API in the page geometry workflow before the affected page, resource, field, or catalog object is finalised
- Keep object names, field names, resource names, and returned handles stable until the document is finalised
- Page-level changes affect subsequent operators on the same page; save and restore graphics state when a temporary setting should not leak
