The Transform fields were sized from the row's room, the rotation field was
70 pt, the corner radius 80, Opacity 64, the stroke weight 90 and Keyboard
Increment 80, so the fields didn't line up. One `panels::field_width`, the
Transform fields' width measured from the full row, now sizes all of them (and
the Edit Artboards fields, and the Transform panel's corner radius).
