Implemented #7100 (initialize layer mask with a copy of the image) 

2002-02-20  Michael Natterer  <mitch@gimp.org>

	Implemented #7100 (initialize layer mask with a copy of the image)

	* app/core/core-types.h: added ADD_COPY_MASK and ADD_INV_COPY_MASK
	enum values.

	* app/pdb/layer_cmds.c
	* libgimp/gimpenums.h
	* plug-ins/script-fu/script-fu-constants.c
	* tools/pdbgen/enums.pl: regenerated.

	* app/core/gimplayer.c (gimp_layer_create_mask): implement
	the new layer mask add modes.

	* app/gui/layers-commands.c (layers_add_mask_query): added radio
	buttons for the new modes.

	* app/paint-funcs/paint-funcs.c (flatten_region): this function
	was never needed so nobody noticed that it never worked. Fixed now.

	* app/undo.c
	* app/core/gimplayermask.h
	* app/core/gimpimage.c: the "mode" field of LayerMaskUndo is
	obsolete since some earlier 1.3 layer mask change. Removed it.
	(Makes mask undos work again)
