	A patch from Federico to add a spiral gradient type. The patch
	has been slightly modified to allow both clockwise and anticlockwise
	spirals and the numbers used to represent these types of gradients
	have been made to follow on from currently allocated numbers (I hope
	this will not break any scripts).
