Box draw and related glyph outlines should extend to the full height of
the OS/2 WinAscent+WinDescent (or Typo...Ascender+LineGap+Descender if
using fsSelection bit 7 in a version 4 OS/2 table, which I doubt is the
case in EversonMono). These metrics determine the non-clipping zone and
also, in almost all Windows applications, the default vertical linespacing.
