Usage notes
- Use this API in the graphics and color management workflow before the affected page, resource, field, or catalog object is finalized
- Keep object names, field names, resource names, and returned handles stable until the document is finalized
- Register named color resources before using them from page-level painting commands
- Page-level changes affect subsequent operators on the same page; save and restore graphics state when a temporary setting should not leak
