[racket] slideshow latex generates poor quality pdf

I don't have time to dig into this right now, but just for the record it
may be a transparency problem of the pngs. Adding a colored background may
solve the issue.
Changing the resolution of the images with `(latex-dpi 600)' (instead of
150) does not change anything.
