Reviewed by Eric Seidel.

Change RenderTableSection cell width, row height and border calculations
back to use integers. Table layout is done on integer bounds to comply
with the specification and to ensure that columns given the same width,
including percentage widths, are rendered with identical widths. The same
applies to heights.

No new tests.
