- The Image Trace panel's Advanced options sit under a full-width collapsible header (widgets::section_toggle, also used by New Document's Advanced Options); whether it is open is kept with the UI preferences. - View: Tracing Result, Tracing Result with Outlines, Outlines, Outlines with Source Image and Source Image, in the panel, the Control bar and the Properties panel. The view is saved in the Image Trace object's settings (`trace.view`), kept when it is traced again, set with the new `imageTrace.setView` command (or `view` on imageTrace.make) and drawn by the canvas only (RenderOptions::trace_views): exports, printing and Expand keep the tracing result.

//! An Image Trace object is a group whose `trace` holds `{preset, params, view}` (see

//! `imageTrace.make`). The view is a viewing aid only: exports, printing and Expand always use the

//! tracing result, whatever it is set to.
