As in Photoshop, right-clicking the W or H field of the Free Transform
(and Free Transform Path) options bar opens a menu of units: Pixels,
Inches, Centimeters, Millimeters, Points, Picas and Percent, the
current one checked. W and H then show the box's size in that unit at
the document's resolution (1200 px at 300 ppi is 10.16 cm), and a
value typed in it scales the box to that length; Percent, the default,
is the scale as before. The pick is remembered with the dialog
settings (`dialogs["edit.freeTransform"].sizeUnit`).
The menu is the rulers' unit menu (`rulers::unit_menu`), the
conversion is the Properties panel's `LenUnit`, and the size limits and
the link toggle work on the scale as before. Length fields are wider
(84 pt) so "2116.67 mm" fits; Percent keeps its 66 pt.
