/* TTBD
Need to add support for SPECTRAL_NM SPECTRAL_PCT type spectral values.
i.e. format with wavlength then corrsponding value.
See /src/argyll/test/JosvanRiswick/R080505.cgt
Do we need to worry about normalising display values to Y = 100, or marking
them not normalised ?
Should have an option to output .ti1 files instead of .ti3 ?
Should parse and support XRGA & Polarized tags.
We could then add an XRGA selection for the output.
