	* app/widgets/gimpcurveview.[ch]: port the "xpos" API
	to [0.0..1.0] doubles too.

	* app/tools/gimpcurvestool.[ch]: rename "col_value" member to
	"picked_color" and use gdouble instead of gint. Also use GimpCurve
	API to map the values instead of accessing the curve directly.
	Fixes setting curve anchor points by color picking.
