Cover previously-untested Canvas methods in CanvasTest:

  • item creation and types, bbox, coordinate conversion, move/scale, find and addtag queries, tags, item configuration, stacking order, text-item editing, selection, focus, scan and postscript;
  • the create_arc, create_oval, create_bitmap, create_image, create_text and create_window item creation methods, checking coordinates, default and explicit options, valid enumerations and rejection of invalid values;
  • tag_bind() and tag_unbind(), checking the returned function id and binding script, querying bound sequences, the add parameter, event delivery to items via a tag, and removal of a single binding by id or all bindings for a sequence.

create_bitmap() does not report an unknown bitmap name on macOS/Aqua,
where bitmaps are resolved lazily.
