2001-01-29 Michael Natterer <mitch@gimp.org> * app/apptypes.h: removed the "Layer" typedef. * app/layer.[ch]: removed the defines of the old function names. Don't implement methods of the parent class (get_name, get_tattoo, ...) but define them as macros. They will go to a separate "pdb_glue.h" header because they are used only by the PDB to simplify code generation (no application file should say gimp_layer_get_tattoo() but always gimp_drawable_get_tatoo()). * app/channel.h * app/channel_ops.c * app/channels_dialog.c * app/commands.c * app/convert.c * app/disp_callbacks.c * app/floating_sel.[ch] * app/gdisplay.c * app/gimage.c * app/gimage_mask.c * app/gimage_mask.h * app/gimpdnd.c * app/gimpdrawable.h * app/gimpimage.[ch] * app/gimplayermask.h * app/global_edit.c * app/image_new.c * app/layer_select.c * app/layers_dialog.c * app/resize.c * app/undo.c * app/xcf.[ch] * app/pdb/drawable_cmds.c * app/pdb/floating_sel_cmds.c * app/pdb/image_cmds.c * app/pdb/layer_cmds.c * app/tools/bucket_fill.c * app/tools/by_color_select.c * app/tools/clone.c * app/tools/crop.c * app/tools/edit_selection.c * app/tools/ink.c * app/tools/move.c * app/tools/paint_core.c * app/tools/rect_select.c * app/tools/text_tool.c * app/tools/transform_core.c * tools/pdbgen/pdb/drawable.pdb * tools/pdbgen/pdb/floating_sel.pdb * tools/pdbgen/pdb/image.pdb * tools/pdbgen/pdb/layer.pdb: changed accordingly, cleanup.
