Positioned elements change size

 Testcase: http://pages.prodigy.net/chris_beall/Amaya/positionedbox.html

It's my understanding that positioning an element should not alter the
dimensions of that element, unless the positions of two OPPOSITE sides (e.g.
top and bottom) are specified.

In the testcase above, Amaya increases the size of elements which are either
'absolute' or 'fixed' positioned, when two ADJACENT sides have been
specified with the positioning.

Compare this rendering with Opera, Firefox, or even IE6, all of which leave
the element size unchanged.

[The test case shows several other issues, but this post is intended to
address the size issue only.]
