Draw freeform paths with the Pencil tool says a small star appears on
the Pencil when it is ready to draw a freeform path, and Reshape paths
with the Pencil tool says the star disappears over a selected path the
drag reshapes. The Pencil cursor had no star.
- New Cursor::PencilNew: the Pencil's crosshair with a small star where
the closing cursor has its ring. It becomes the crosshair with Use
Precise Cursors and as a system cursor.
- The Pencil shows it before a press when neither find_extend nor
find_redraw (the lookups the press uses, within Edit Selected Paths)
finds a selected path under the pointer. Over such a path and while a
stroke is drawn, the cursor has no star.
