inverted y axis
I'm writing a 2.5d cam program, and I'm a bit stuck on a problem.
G-code generally assumes a right-hand cartesian plane (y-axis points up, x-axis points right), but a lot of processes in computer graphics (svg) use a left-hand plane (y-axis points down, x-axis points right). My program currently uses a left-hand plane, and converting it to a right-hand plane is not trivial, and would make the code rather inelegant.
would it be acceptable if I add a feature that allows you to set an arbitrary zero point on the left-hand plane? Would this be a hindrance to the user experience, or a cool feature?
