To make the options simple, what about doing as follows?



* --bigpdfs / -b

Keep its behavior

i.e.
- Define and use some encodings for Emmentaler. (Also using "show"
instead of "glyphshow")
- For PDF output, embed full set (non-subset) font (if there is no bugs
in Ghostscript)

This option is for full set (non-subset) embedded font intermediate
PDFs, and later uses MuPDF etc. to remove duplicate the fonts.

This method is simple and easy to understand.
However, the size of the intermediate PDF increases.
Also, the current Ghostscript does not work properly because there seems
to be a bug in which full set of fonts can not be embedded.



* -dgs-neverembed-fonts

Add behavior

Current behavior
- For PDF output, It does not embed fonts except TrueType fonts.

Added behavior
- Define and use some encodings for Emmentaler. (Also using "show"
instead of "glyphshow")
- For PDF output, It does not embed fonts except TrueType fonts.

This option is for non-embedded font intermediate PDFs, and later uses
Ghostscript to embed missing fonts.

This method needs to pass the missing fonts to Ghostscript.
In other words, it is for specialists.
However, if it is used properly, it works even with the current
Ghostscript.
