When loading schematics/pcbs, notification of font replacements might be
warranted but in libraries, this warning is not helpful and intrusive
(cherry picked from commit 11c6164934)
We can't assume that the ignored connection exists when trying to set
the junction size. We use int_max for the default instead of 0 so that
later, we don't try to create a minor track with 0 width in loadNets()
