Hi Stefano, Since I've been playing with this for the past few days, I thought I would offer my findings so far.
SVG can also be used to wrap bitmap images, but I wouldn't recommend it. For the professional writing book, I've been experimenting with support for the different formats and trying to see which one offers the best output (for both screen and print). (Since there's an entire chapter dedicated to images and exchanging data between programs, I've had plenty of time to play.) So far, the leader seems to be PDF (with EPS running a close second place), at least when using pdflatex. I've experienced occasional weirdness when processing with XeTeX and still haven't been able to determine why. Unfortunately, SVG doesn't fare so well. At least on my Ubuntu 9.10 box, LyX has a hard time converting the images for preview and LaTeX will produce all kinds of strange output. Especially if the SVG makes use of unsupported tags. And of course, both Inkscape and Adobe Illustrator will produce SVG with tags that other applications don't recognize. (And just because it is SVG doesn't mean that another SVG editor will be able to read it. See http://www.oak-tree.us/blog/index.php/2008/12/13/wpf-svg-xaml-part1 for more.) Luckily, however, Inkscape has FANTASTIC support for exporting to PDF. (I only discovered this the other day and Inkscape has now become my new favorite program.) It can import PDF files from Adobe CS3 and other programs (while maintaining full support for text and other elements), resize the document boundaries and then export back to PDF seamlessly. It also handles technical drawings created in Dia and Kivio (native file formats for both programs). I've even had good luck with material from Visio (if it's first been exported to PDF). For raster images, it seems like PNG works the best (though most of the raster images I've been using are screenshots). A friend who does layout/design has suggested that I spend some time with PDF raster images, but I haven't yet seen the need. Hope this is of some help.

You can wrap bitmap files in it, I think (e.g. when scanner software offer a "Save as pdf" option). File format in itself is not necessarily an indication of bitmap vs. vector graphics. With the possible exception of SVG, perhaps (which I use but am pretty ignorant about)?
