parbox <-
auto_crop: boolIf @on, the
width of the parbox as a graphical
object is made to fit exactly the content. If @off
(default), the width is the minimum of the parbox<-line_width
and the width of the content.
Auto cropping is used mostly for defining table-cells, where the
natural width of the cell is (initially) determined by the content.
If parbox->geometry
is invoked with an explicit width, parbox<-auto_crop
is automatically set to @off,
trying to fullfil the requested width as closely as possible.
