Indeed, I didn't know much about size-in-pixels but since the
first example I saw used it, I kept using it. But now I got
it. The images show up nicely now.

Except one thing I just noticed. An 'ã' which appears in a
page-item, shows up ok while running the presentation but in the
postscript shows as a 'ª'.

Do I need to add any escape character in drscheme for it to
convert correctly?

Oh, and is it possible to convert also to postscript the
slideshow comments? Maybe the comments should come at the end or
right after their respective slide?
