Oh, I was familiar with that, but, the Concern there ( "faster execution") is
that "Faster execution" is not the same as "ordering" a file for *needs*. So I
don't think any Controller would ever get that issue right.

Even for vinyl cutting, Your best off having the drag knife starting and ending
on a corner node, not in the middle of a curve. Seldom does it matter The order
of which line to cut first with Vinyl, because there is nothing to fall loose
or out of place. I have the option to select the hpgl output as "drawn" (which
includes editing any and all vectors for direction, start point and even
depth), From left to right, right to left, top down or bottom up. But, that's
at the design software.

Obviously, when CNC Routing or machining, The "faster execution" can be a
hazard ! Its a good Idea to cut "holes" before the "profiles"...
