2003-11-10 Michael Natterer <mitch@gimp.org> * libgimpwidgets/Makefile.am * libgimpwidgets/gimpwidgets.h * libgimpwidgets/gimpwidgetstypes.h * libgimpwidgets/gimpcolorselection.[ch]: new widget derived from GtkVBox. Contains a GimpColorNotebook, GimpColorScales and new/old color areas as known from the app's color_notebook. Will soon be used to replace GtkColorSelection for plug-ins. * app/gui/color-notebook.c: removed most code and use a GimpColorSelection widget. Moved the "Reset" button to the action_area. Cleanup.
