[Openicc] review of new wide gamut editing space

[Kai-Uwe Behrmann]

Hello all,

some software projects want to preserve wide gamut data like originating 
from cameraRAW. ProPhotoRGB, which's gamut appears quite reasonable,
specifies unfortunately a gamma of 1.8, which is not good for 2.2/sRGB 
style display systems. Ideally we find a colour space to use as a intermediate 
space for displaying and storage for inclusion into the OpenICC profile 
collection.

I created a editing profile with gamma of CIE*L following the 
ECIv2/LStar-RGB profile and used the wide gamut colour primaries of 
ProPhotoRGB alias ROMM [1].

Please find the new profile attached for review and comments.
In case you know a freely distributable existing alternative or like to 
create one, that would be welcome as well.


kind regards
Kai-Uwe
