PDFDocument.close()
Close the document and free its resources; resolves once they are released. A viewer still open on it refuses undo, redo,
snapshot() and Download with a reported DOCUMENT_CLOSED (its exporter rejects with it): destroy the viewer, or open a new document. After Kernstra.destroy() has recovered from an ENGINE_FAILED fault the document is already released, and close() does nothing.methodLifecyclesince 1.0.0
