Thanks for your advice, but it doesn't answer my question.  Please review
my initial post.  What combination of metrics should be used to set the
initial pen position appropriately?  ie How far below and to the right of
the upper left corner of a text box should the origin of the first
character be?  See
https://www.freetype.org/freetype2/docs/glyphs/glyphs-3.html for a
reference about glyph metrics.  An answer to my question would involve a
pair of integer expressions in terms of the members of FT_FaceRec and/or
FT_GlyphRec.
