2001-12-12 Michael Natterer <mitch@gimp.org> * app/core/Makefile.am * app/core/gimpimage-pick-color.[ch]: new files. gimp_image_pick_color() doesn't set the FG or BG color and doesn't touch the current palettte. * app/tools/gimpcolorpickertool.[ch]: removed the actual picking code, set the user_context's FG or BG color here. * app/gui/palette-editor.[ch]: s/palette_set_active_color/palette_editor_update_color/, don't set the FG and BG color here. The function is still #if 0'ed. * app/gui/toolbox.c: fixed WM resize hints in toolbox_style_set(), code cleanup. * app/tools/gimppainttool.[ch]: some cleanup before chopping. * app/tools/gimpsmudgetool.c: changed accordingly. * tools/pdbgen/pdb/misc_tools.pdb: removed the possibility to set the FG or BG color or add the picked color to the active palette bacause it doesn't belong here. Palette PDB wrappers are on the TODO anyway. * app/pdb/misc_tools_cmds.c * libgimp/gimpmisctools_pdb.[ch]: regenerated. * plug-ins/perl/examples/image_tile * plug-ins/perl/examples/logulator * plug-ins/script-fu/scripts/hsv-graph.scm * plug-ins/script-fu/scripts/title-header.scm: changed accordingly.
