Changes

As mentioned earlier, transparent colors can be produced by setting the <tt>t</tt> value for the color. Hans Hagen posted the following sample code for transparent colors on the mailing list on 2005-07-13; the yellow blocks have been added to demonstrate the order in which the blocks are drawn on the page; the first yellow block is behind the transparent red and blue blocks, while the second is in front of them.
