box-layout: Fix child offsets

Browse Source 
Currently, BoxLayout interprets the box passed into allocate() in
a fairly peculiar way:
 - in the direction of the box, all space between [xy]1 and [xy]2
   is distributed among children (e.g. children occupy the entire
   width/height of the box, offset by [xy]1)
 - in the opposite direction, expanded children receive space
   between [xy]1 and the height/width of the box (e.g. children
   occupy the width/height of the box minus [xy]1, offset by [xy]1)
The second behavior doesn't make much sense, so adjust it to interpret
the box parameter in the same way as the first one.
