- app: gimp_context_get_(foreground|background)() are now returning a GeglColor. - libgimp: PDB functions named similarly in libgimp are returning a newly allocated GeglColor too. - A few other PDB functions (the ones using these functions) were updated and their signature changed to use GeglColor too, when relevant. Plug-ins which use any of the changed libgimp functions were fixed. - GimpContext: signals "(foreground|background)-changed" are now passing a GeglColor. - libgimpconfig: new macro GIMP_CONFIG_PROP_COLOR using gegl_param_spec_color(). - GimpContext: properties "foreground" and "background" are now GeglParamColor properties. - app: All code interacting with GimpContext objects were updated to receive a GeglColor (that they may still convert, or no, to GimpRGB for now). - app: gimp_prop_gegl_color_button_new() was added as an alternative to gimp_prop_color_button_new() when the property is a GeglParamColor. Eventually the former should replace completely the latter. - libgimpwidgets: gimp_prop_color_area_new() now works on GeglParamColor properties only. - libgimp: gimp_procedure_dialog_get_widget() will generate a GimpColorArea for GeglTypeParamColor arguments.
