Description:
Allow use of Identity-H CMap and CID versions of Emmentaler

When -O TeX or -O TeX-GS is given, lilypond generates
postscript code that instructs ghostscript to use the
Identity-H CMap and CID versions of the emmentaler
fonts. Used e.g. by 'make doc'.

Without '-O TeX' or '-O TeX-GS' we still use the
traditional postscript code.

Documentation is missing.

Only a proof of concept, definitely not ready for
release.

Tested only with current lilypond and ghostscript master.
