Hi Lars - thanks much for all the investigations.
tftopl naively reports the latter
tftopl is just reporting what it sees, right? Can't blame it for that.
Yes; vptotf isn't all that detailed in its messages
So maybe this is where the fix should lie: vptovf should not report
variances in design size up to <some amount>, because of the difference
between mf and tfm representations/resolutions. Wdyt?
The discrepancy seems worth reporting to Knuth (for 2020 ...). Whether
he'll deem it worth a reward, have to see.
