# The AAT ‘cidg’ table has almost the same structure as ‘gidc’,
# just mapping CIDs to GlyphIDs instead of the reverse direction.
#
# It is useful for fonts that may be used by a PDF renderer in lieu of
# a font reference with a known glyph collection but no subsetted
# glyphs.  For instance, a PDF can say “please use a font conforming
# to Adobe-Japan-1”; the ‘cidg’ mapping is necessary if the font is,
# say, a TrueType font.  ‘gidc’ is lossy for this purpose and is
# obsoleted by ‘cidg’.
#
# For example, the first font in /System/Library/Fonts/PingFang.ttc
# (which Apple ships pre-installed on MacOS 10.12.6) has a ‘cidg’ table.
