2001-03-06 Michael Natterer <mitch@gimp.org> * app/gimage.[ch]: removed the layer mask functions. * app/gimpchannel.[ch]: added a boolean "dummy" parameter to gimp_channel_copy() so it has the same signature as gimp_layer_copy() and can be used by the GimpDrawableListView to generically duplicate drawables. * app/gimpcontainerview.c: call "select_item" with a NULL item before changing the underlying GimpContainer so subclasses have a chance to update (e.g. set button sensitivity). * app/gimpdnd.c: folded all the GtkType comparing code into a utility function (much more readable now). * app/gimpdrawablelistview.[ch]: activated the "raise", "lower", "duplicate" and "delete". I'm not really happy with all those function pointers passed to the constructor (and the dummy parameters I've added to some GimpChannel functions) -- OTOH the generic view maybe worth the "gboolean dummy" cruft hanging around in the channel class. * app/gimplayer.[ch]: removed the "apply_mask", "edit_mask" and "show_mask" booleans ... * app/gimplayermask.[ch]: .. and added them here together with proper accessors and "*_changed" signals. This also makes the layer mask undo code much clearer as we don't have to store the booleans separately. * app/gimplayerlistitem.c: badly hacked to acheive the correct indicator being drawn around the active drawable. This needs a new GimpPreview function for setting the border color. * app/gimplistitem.c: smaller horizontal spacing. * app/gimppreview.[ch]: added the "border_width" parameter also to gimp_preview_set_size() so we can modify all previews the same way after creation. * app/layers_dialog.c: no need to push an undo group around the "duplicate layer" code. Was this an artefact or did I miss something here ??? * app/channel_ops.c * app/channels_dialog.c * app/gimage_mask.c * app/gimpcontainergridview.c * app/gimpcontainerlistview.c * app/gimpdrawablelistitem.c * app/gimpimage.[ch] * app/qmask.c * app/test_commands.c * app/undo.c * app/xcf.c * app/pdb/channel_cmds.c * tools/pdbgen/pdb/channel.pdb * app/pdb/selection_cmds.c * tools/pdbgen/pdb/selection.pdb: changed accordingly. * app/pdb/internal_procs.c * app/pdb/layer_cmds.c * libgimp/gimplayer_pdb.[ch] * tools/pdbgen/pdb/layer.pdb: commented out the layer mask accessors from the perl code, so the functions temporarily disappeared all over the place. * plug-ins/Makefile.am: don't build XJT until the layer mask stuff is back. * pixmaps/eye.xpm: cropped it to it's minimal size.
