	Cleaned up the remaining libgimp API issues:

	* libgimp/gimppixelfetcher.[ch] (enum GimpPixelFetcherEdgeMode):
	added new enum value GIMP_PIXEL_FETCHER_EDGE_BACKGROUND so we
	can actually use the bg_color feature of the GimpPixelFetcher.

	(gimp_pixel_fetcher_new): added "gboolean shadow" parameter
	because it must not change while the GimpPixelFetcher exists.

	(gimp_pixel_fetcher_set_shadow): removed.

	(gimp_pixel_fetcher_set_bg_color): added "GimpRGB *color"
	parameter and don't call gimp_palette_get_foreground().

	(gimp_pixel_fetcher_get_pixel): handle BACKGROUND mode. Cleaned up
	the function.

	(gimp_get_bg_guchar)
	(gimp_get_fg_guchar): removed these functions...

	* libgimp/gimpdrawable.[ch]: ...and added
	gimp_drawable_get_color_uchar() instead.

	* libgimp/gimp.def
	* plug-ins/common/blinds.c
	* plug-ins/common/checkerboard.c
	* plug-ins/common/cubism.c
	* plug-ins/common/curve_bend.c
	* plug-ins/common/displace.c
	* plug-ins/common/edge.c
	* plug-ins/common/illusion.c
	* plug-ins/common/mblur.c
	* plug-ins/common/mosaic.c
	* plug-ins/common/plasma.c
	* plug-ins/common/polar.c
	* plug-ins/common/ripple.c
	* plug-ins/common/shift.c
	* plug-ins/common/spread.c
	* plug-ins/common/tileit.c
	* plug-ins/common/whirlpinch.c
	* plug-ins/gflare/gflare.c
	* plug-ins/libgimpoldpreview/gimpoldpreview.c: changed accordingly.

	(Didn't test the changed plug-ins because I wanted to get this
	API change into CVS as soon as possible)
