Support for Pgenerator

[lillgunde]

A great future feature for the modernization of Displaycal would be Pgenerator support.

Also,
When using the "Auto-Optimized" selection under the profiling tab there is no way of knowing what
patches are being sent to the renderer/patch generator.

It would be nice if you could specify what output the software is sending the pattern generator.
REC.709 /D65 , BT2020 /D65, BT2020 P3/65 etc. and adjust the patterns accordingly.

I believe you can condition the first set of patches to be picked from a certain gamut so that instead of randomly firing patches Argyll generates patches from a known gamut, which I believe more or less matches your request.

To do that:

1. Go the profiling tab
2. In the Profile type section, select the cog wheel icon:
   
3. Select the profil from the source profile section
   

P.S: Just to let you know, there is a bug related to that dialog, I'll create a bug report for that.
