multiplyInverseXYZW Method

multiply matrixInverse * [x,y,z] and return packaged as Point4d with given weight.

• Equivalent to solving matrix * result = [x,y,z]
• return as a Point4d with the same weight.
• Called by Transform with x,y,z adjusted by subtraction ((xw) - w * origin.x, etc) where xw is the pre-weighted space point.
