Change metapage command to switch text size only locally
Hi, I just discovered that the explicit change of the font size in the
\metapage commands affects the remaining text.
\includes for the different parts of the frontmatter (and chapters etc.) and improve single chapters by means of
\includeonly for faster rendering.
Then I discovered that a chapter was warning-free if I only compiled the chapter alone (or the whole thesis without the meta page), but 4 underfull vboxes were reported if I also include the metapage.
Unfortunately, I have no in-depth understanding of what's going on, but could avoid this problem with the change of this merge request.
