[Openicc] What is exactly needed: Gutenprint GUI selectors

Hello list, hello robert,
If we have a serialized Gutenprint Settings, I would recommend to use 
following qualifiers / selctors as part of the setting, which are 
displayed in the printing GUI (e.g. CPD)

1) MediaType (Should be detailed as needed)
- Photopaper Generic
- Epson Photopaper 210g

2) Resolution / Quality Mode
360 DpI - draft
720 DpI - High Quality
1440 DpI - Best Quality

These qualifiers could be used either in a PPD, from which the Printing 
GUI is generated or they could be used as ICC profile DictType 
Meta-data, if a Colormanagement Framework like e.g. g-c-m or Oyranos is 
involved in creating the printing GUI.
In the last case, the PPD should be stripped of from color relevant entries.

Please note for the ICC case, that I would additionally include the 
complete settings also as ICC dictType Meta-data.
The two qualifiers / selectors are used to create the Printing GUI from 
the available printer ICC-profiles but hiding the profile filenames from 
the user interaction.

The complete driver settings have to be communicated to 
rastertogutenprint (e.g. as CUPS job ticket data extracted from the ICC 

Best regards
