Since this propagating backwards is unbounded, it is not something you want to be doing in real time. So, it might have to be done when the file is read in. But, it should solve a number of problems, such as high speed contouring, where there is a pass with bumpy Z moves across a surface, and then a roughly 180 turn to scan back the other way.
