Underscore too bold

[automatedbugreportingfacility]

This is a regression from PR #4615. The underscore for the last 2 chars in "NUMERO D’IMMATRICULATION" is too bold.

Enforce minimum line widths

[Snuffleupagus]

That looks "fun". Compared to the recent issue #6117, this is unfortunately not related to the fact that we fail to invalidate the getSinglePixelWidth cache. Rather the issue seems to be that, for that particular line, the actual getSinglePixelWidth method returns an "incorrect" value.

Unfortunately I've no idea how to address that :-(
Given the number of issues/bugs fixed by PR #4615, and considering how broken the rendering of some of those PDF files were before that PR, backing it out isn't really an option in my opinion.

Agreed, I've got another regression where getSinglePixelWidth might be falling short, and it's NOT from PR #4615, but PR #4521. If you're interested in looking into that, I can file a separate issue or paste it here.

Please open a new issue; if it turns out that the issues are in fact the same, we can always close one as a duplicate of the other.

@calixteman It seems that PR #12812 actually regressed this even further, can you please take a look?
