	* libgimpcolor/gimprgb.h (GIMP_RGB_INTENSITY): removed the
	addition of 0.001 that isn't correct for use with integers (should
	be 0.5 then) and just plain wrong for use with floats/doubles.

	* app/base/temp-buf.c
	* app/core/gimpdrawable.c
	* app/core/gimpimage-convert.c
	* app/core/gimpimage.c
	* plug-ins/common/aa.c
	* plug-ins/common/engrave.c
	* plug-ins/common/gradmap.c
	* plug-ins/common/newsprint.c
	* plug-ins/gflare/gflare.c
	* plug-ins/gfli/gfli.c
	* plug-ins/pagecurl/pagecurl.c: add 0.5 to the result of
	GIMP_RGB_INTENSITY() in all places that use it with integers.
