gimp/app/display/gimpdisplayshell-layer-select.c
Michael Natterer af976a75c3 app: add a GimpColorConfig to GimpDisplayShell 
Use the shell's color config for color managing the display and
various auxiliary widgets attached to it, like the notebook tab widget
and navigation popup.

The config is currently just a reference to the global prefs config,
so no behavior changed.
