Subject: Space around images in LaTeX output is sometimes a bit large

When we look at images in documents we see for a number of images a big amount of white space around the image.
This is e.g. the case in the doxygen manual at page 99 of the 1.8.20 version.

- using `\raggedbottom` sees to it that the space inside the page is removed (there might be some white space when the next image doesn't fit anymore. (See https://tex.stackexchange.com/questions/566779/placing-figures-on-a-fixed-place-without-lot-of-space-around-it)
- use `\centering` instead of `\begin{center}` as the center environment adds some extra white space (see a comment with the question, on a different subject though: https://stackoverflow.com/questions/64328597/pdftex-warning-saying-about-duplicate-figures#comment113772445_64328597)
