nl_tokens: Returns the group bounding box . Behaves like {
pl_tokens: function ( ) { var i = 0 , sprite , bb , items = this . items , len = this . length , infinity = Infinity , minX = infinity , maxHeight = - infinity , minY = infinity , maxWidth = - infinity , maxWidthBBox , maxHeightBBox ; for ( ; i < len ; i ++ ) { sprite = items [ i ] ; if ( sprite . el && ! sprite . bboxExcluded ) { bb = sprite . getBBox ( ) ; minX = Math . min ( minX , bb . x ) ; minY = Math . min ( minY , bb . y ) ; maxHeight = Math . max ( maxHeight , bb . height + bb . y ) ; maxWidth = Math . max ( maxWidth , bb . <mask> + bb . x ) ; } } return { x : minX , y : minY , height : maxHeight - minY , width : maxWidth - minX } ; }
