[bug #57506] Erroneous "slant" value in Times italic font(s) for ps device

Show all headers | View raw

Follow-up Comment #4, bug #57506 (project groff):

You raise important questions, to which I don't know any answers.  You
demonstrate more font knowledge in comment #2 than I have in my entire brain.

A question also relevant to bug #58894 and bug #58897.

Werner probably knows the answer.

http://lists.gnu.org/archive/html/groff/2020-08/msg00024.html suggests that
John Gardner knows a thing or two about fonts as well.

Bug #57594 also concerns an update that should be done every release cycle.  I
wondered there (and haven't investigated any further to try to answer myself)
whether there's a checklist of updates to run for each release.

One would ideally hope the original font files contain correct data, or that
if they don't, bugs can be reported somewhere to get them corrected, so that
we don't have to patch font metrics for every release in perpetuity.
