7# The AAT ‘cidg’ table has almost the same structure as ‘gidc’,
8# just mapping CIDs to GlyphIDs instead of the reverse direction.
9#
10# It is useful for fonts that may be used by a PDF renderer in lieu of
11# a font reference with a known glyph collection but no subsetted
12# glyphs.  For instance, a PDF can say “please use a font conforming
13# to Adobe-Japan-1”; the ‘cidg’ mapping is necessary if the font is,
14# say, a TrueType font.  ‘gidc’ is lossy for this purpose and is
15# obsoleted by ‘cidg’.
16#
17# For example, the first font in /System/Library/Fonts/PingFang.ttc
18# (which Apple ships pre-installed on MacOS 10.12.6) has a ‘cidg’ table.
