[Openicc] review of new wide gamut editing space

[Jan-Peter Homann]

Hello to all,
Working with wide Gamut Images makes oonly sense with 16 Bit data.

In this case the question of Gamma 1,8 2,2 sRGB or L* is not problem. 
ProPhoto RGB standardized through ISO and Thousand users of Adobe 
Photoshop and Lightroom working with is successfully as an intermediate 
step between vendor specific RAW and outputspaces like e.g. sRGB.

I don´t see the need that the Open Source Community would need an extra 
wide gamut space.

Best regards
Jan-Peter
