left-bound-info and right-bound-info are calculated at the beginning of
Line_spanner::print, so this setting of Beam properties, albeit late in
the game, would be in keeping with the stage at which these properties
are calculated in the Line_spanner.  Granted, I could be using one bad
practice to justify another, but it seems like in the Line_spanner case,
this is an appropriate place to calculate this information.
