RsvgLength values are used in [methodRsvg.Handle.get_intrinsic_dimensions], for
example, to return the CSS length values of the width and
height attributes of an <svg> element.
It is up to the calling application to convert lengths in non-pixel units
(i.e. those where the unit field is not RSVG_UNIT_PX) into something
meaningful to the application. For example, if your application knows the
dots-per-inch (DPI) it is using, it can convert lengths with unit in
RSVG_UNIT_IN or other physical units.
