Gimp/app/display/gimpcursorview.c
Jehan 86854ee66f app: GimpColorFrame is now much more space aware. 
This one is kind of a huge deal, because the info returned by the color frame
was kind of messy (even though it improved lately, but space associated to color
data had to be kept in-sync by hand, which was bug-prone).

Now the color frame stores the data as a GeglColor, always aware of its space
and therefore able to do much nicer conversion. Also RGB and Grayscale options
now display the profile name of the color space (until now, we had only this for
the CMYK option using the proofing profile).

I still wish to get more options. Typically some people may want to get
RGB/Grayscale/CMYK values to other spaces (maybe sRGB, one of their favorite
profile as set in Preferences or just any random profile which they could load
from disk). Giving such ability to basically live-convert their pixel data to
various other color space would be very nice. We'll see if this will be
implemented for GIMP 3 or for after.
