2003-05-16 Michael Natterer <mitch@gimp.org> * app/core/gimpimage-mask.[ch] (gimp_image_mask_extract): added "gboolean cut_image" parameter so we can float selections without cutting them from the original drawable. * app/gui/select-commands.c * tools/pdbgen/pdb/selection.pdb: pass cut_image == TRUE. * app/pdb/selection_cmds.c: regenerated. * app/tools/tools-enums.[ch]: added SELECTION_MOVE_COPY value to the SelectOps enum. * app/tools/gimpselectiontool.c: use the new mode when <ctrl>+<alt>-dragging a selction (yes, this is evil but there are no modifiers left). * app/tools/gimpeditselectiontool.[ch]: extended EditType enum by EDIT_MASK_COPY_TO_LAYER_TRANSLATE and pass cut_image == FALSE if it's passed to init_edit_selection(). * app/tools/gimpfreeselecttool.c * app/tools/gimpfuzzyselecttool.c * app/tools/gimprectselecttool.c: pass the new mode to GimpEditSelectionTool.
