		There may be non-blend args at the top of the stack. We first calculate
		where the blend args start in the stack. These are the last
		numMasters*numBlends) +1 args.
		The blend args starts with numMasters relative coordinate values, the  BlueValues in the list from the default master font. This is followed by
		numBlends list of values. Each of  value in one of these lists is the
		Variable Font delta for the matching region.

		We re-arrange this to be a list of numMaster entries. Each entry starts with the corresponding default font relative value, and is followed by
		the delta values. We then convert the default values, the first item in each entry, to an absolute value.
