Ah, good to know you, or rather your patches, are affected, too :-)

Your changes look beautiful in my eyes. Symbol and float atom are still
one pixel less tall than object and message boxes, but I don't know if
you actually intended to make them the same. Box width is the same as
it was in 0.47/macOS 0.46/Ubuntu 14.04, at least for font size 10. 

Attached is a screenshot of the bugfix/metrics-sizing branch compiled
on macOS 10.11 (Tk 8.6.7) and Ubuntu 16.04 (Tk 8.6.5). Boxes do have
the same dimensions on each platform.

Thanks for your work!
