% Load a TrueType font from a file as a Type 42 PostScript font.
% The thing that makes this really messy is the handling of encodings.
% There are 2 interacting tables that affect the encoding:
% 'cmap' provides multiple maps from character codes to glyph indices
% 'post' maps glyph indices to glyph names (if present)
% What we need to get out of this is:
% Encoding mapping character codes to glyph names
% (the composition of cmap and post)
% CharStrings mapping glyph names to glyph indices
% (the inverse of post)
% If the post table is missing, we have to take a guess based on the cmap
% table.
