Michael Natterer 65235b91a9 new function gimp_drawable_set_visible(). Renamed gimp_drawable_visible()
2001-03-04  Michael Natterer  <mitch@gimp.org>

	* app/gimpdrawable.[ch]: new function gimp_drawable_set_visible().
	Renamed gimp_drawable_visible() to gimp_drawable_get_visible().
	Added a "visibility_changed" signal.

	* app/gimplistitem.[ch]: new virtual function "set_viewable"
	which allows subclasses to connect to the viewable's signals.

	* app/gimpdrawablelistitem.[ch]: added an eye button. Implement
	"set_viewable" to connect to the "visibility_changed" signal.

	* app/gimpchannel.[ch]: removed unused function
	gimp_channel_toggle_visibility().

	* app/channels_dialog.c
	* app/floating_sel.c
	* app/gimage_mask.c
	* app/gimpimage.c
	* app/gimplayer.c
	* app/layers_dialog.c
	* app/xcf.c
	* app/pdb/channel_cmds.c
	* app/pdb/layer_cmds.c
	* app/pdb/pdb_glue.h
	* tools/pdbgen/pdb/channel.pdb
	* tools/pdbgen/pdb/layer.pdb: removed direct access of
	drawable->visible and use the functions instead. Also makes PDB
	code generation nicer.

	* pixmaps/eye.xpm: cropped it a bit.
