	* 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.
