[pdftex] support for svg

[story at uakron.edu]

In the PDF spec, Section 9.4 covers Alternate Representations and there is an
outlined example of use.  The only application that I know of is Adobe Photoshop Album, you 
can create a slideshow presentation and save it to a PDF doc.

Leonard Rosenthol, of PDFSages, announced a SVG plugin available for the free download, 
you must have Acrobat 6.0.  I've tried it and it works  well.  It turns out you only need acrobat 
to embed the svg, someone with adobe reader 6.0 can view the svg without the plug-in.
