Additional notes

@christianparpart already knows the cause and the fix...I can't explain it though!

As discussed locally. This shows two problems.

1. SF Mono font probably does not expose the correct metrics to shift the pen to the right. It looks like it's always 0. This goes in line with the other Apple's font for emoji, where we already auto-center in case of zero-metrics.
2. the underline is too bold for small grid cell heights (IIRC, @cqexbesd is using 12pt size on a standard 96dpi screen)
