/**
* Packer is a layout manager which automatically places child windows
* inside its area against the left, right, top, or bottom side.
* Each time a child is placed, the remaining space is decreased by the
* amount of space taken by the child window.
* The side against which a child is placed is determined by the LAYOUT_SIDE_TOP,
* LAYOUT_SIDE_BOTTOM, LAYOUT_SIDE_LEFT, and LAYOUT_SIDE_RIGHT hints given by
* the child window.  Other layout hints from the child are observed as far as
* sensible.  So for example, a child placed against the right edge can still
* have LAYOUT_FILL_Y or LAYOUT_TOP, and so on.
* The last child may have both LAYOUT_FILL_X and LAYOUT_FILL_Y, in which
* case it will be placed to take all remaining space.
