ViewportLayout.java.layoutContainer rewrite (proposed fix)

The current ViewportLayout.java.layoutContainer method seems behaving
differently from Sun's implementation in the following ways:
1. If the view is smaller than the port where it should be displayed, the view
is bottom aligned. For instance, if the table is displayed in the frame that is
larger than the table size, the table body is bottom aligned (large whitespace
between table header and table body). This is not correct, in Sun's
implementation the table is always top aligned is such case.
2. If the view width is exactly the same as the view port width, it should be
set as such and the view offset must be set to zero, instead of performing
unnecessary calculations.  Somehow the view offset is calculated different from
zero, this results the unexpected whitespace at the left border of the tables
and text areas in the Swing demo.

The patch seems bringing no regressions, as far as I was able to test.

        * javax/swing/ViewportLayout.java (layoutContainer):
        If Scrollable tracks dimension, set view size to the port size. 
        If port is larger than the view, move the view to the top/left.
