2005-07-11 Michael Natterer <mitch@gimp.org> * app/core/gimppickable.[ch]: added GimpPickable::get_opacity_at() * app/core/gimpchannel.[ch]: removed gimp_channel_value() and implement ::get_opacity_at() instead. * app/core/gimplayer.[ch]: removed gimp_layer_pick_correlate() and implement ::get_opacity_at() instead. * app/core/gimpselection.c: GimpChannel::value() doesn't exist any more. * app/core/gimpprojection.c: implement ::get_opacity_at(), always returns OPAQUE. * app/core/gimpimage.c * app/tools/gimpbucketfilltool.c * app/tools/gimpclonetool.c * app/tools/gimpfliptool.c * app/tools/gimpiscissorstool.c * app/tools/gimpnewrectselecttool.c * app/tools/gimprectangletool.c * app/tools/gimpselectiontool.c * app/tools/gimptransformtool.c * tools/pdbgen/pdb/selection.pdb: changed accordingly. * app/pdb/selection_cmds.c: regenerated.
