DND cleanup part 1:

2002-09-02  Michael Natterer  <mitch@gimp.org>

	DND cleanup part 1:

	* app/widgets/gimpdnd.[ch]: changed all gimp_dnd_*_dest_set() and
	_unset() functions to _dest_add() and _dest_remove(). Switch from
	using static arrays of GtkTargetEntries to dynamic GtkTargetLists.
	The _add() and _remove() functions configure the drag dest
	automatically if not already done, so there is no need to call
	gtk_drag_dest_set() on the widget any more. Drag source cleanup
	will follow...

	Renamed silly function names gimp_gtk_* to gimp_dnd_*

	* app/display/gimpdisplayshell.c
	* app/tools/gimpblendtool.c
	* app/widgets/gimpcolormapeditor.c
	* app/widgets/gimpcontainerview.c
	* app/widgets/gimpgradienteditor.c
	* app/widgets/gimplistitem.c
	* app/widgets/gimpmenuitem.c
	* app/widgets/gimppreview.c
	* app/widgets/gimppaletteeditor.c
	* app/widgets/gimpselectioneditor.c
	* app/widgets/gimptoolbox-color-area.c
	* app/widgets/gimptoolbox-indicator-area.c
	* app/widgets/gimptoolbox.c
	* app/gui/about-dialog.c
	* app/gui/color-select.c
	* app/gui/device-status-dialog.c
	* app/gui/tool-options-dialog.c: changed accordingly. Removed
	all calls to gtk_drag_dest_set() and their GtkTargetEntry tables.

	* app/widgets/gimpchannellistitem.c: enabled some commented out
	dnd code (which will not work since dnd needs more love...)

	* app/widgets/gimpitemlistview.[ch]: added a third
	"gboolean interactive" parameter to GimpItemNewFunc.

	* app/gui/channels-commands.[ch]
	* app/gui/layers-commands.[ch]
	* app/gui/vectors-commands.[ch]: if the new_item_func is called
	with "interactive == FALSE", don't pop up a dialog but silently
	create a new item of the image's size.

	* app/widgets/gimpdrawablelistview.c: use the new feature to allow
	color and pattern drops to the "New" button, which creates a new
	layer/channel filled with the color/pattern.
	(special feature for drc ;-)

	* app/widgets/gimppaletteeditor.c: fixed event handling so we see
	the context menu again. Also, don't redraw on "expose", since
	GtkPreview does that for us.
