	* app/core/gimpcurve.[ch]: changed all values to be [0.0..1.0]
	doubles instead of [0..255] integers. Also changed the API to use
	doubles instead of ints. Still have the fixed-size arrays though.

	(gimp_curve_map): new function to map values.

	* app/gegl/gimpoperationcurves.c: remove private map() function
	and use the one from GimpCurve.

	* app/gegl/gimpcurvesconfig.c
	* app/core/gimpdrawable-curves.c: port to the new gdouble API.

	* app/tools/gimpcurvestool.c: use gimp_curve_get_uchar() to get
	the arrays for the color bars.

	* app/widgets/gimpcurveview.[ch]: port to gdouble and some cleanup.
