Feature request - G-code scaling

[ibm78]

I'd like ask you if it is possible to add 3 new input fields for each axis, which will represent online scaling.

Calculation is absolutely simple:
[Coordinate sent to Arduino] = [Coordinate from file] * [Scale]
It means vhen scale is 1.0000 everything is as is now in original size.

This could be very helpful function for users which will allow have only one G code file when you want to produce final cut in different sizes. For example when I'm doing a lot of papercuts of same picture on different formats (A4, A3, A2, etc. ) I need just one G-code...

Thank you in advance for your feedback...

Martin
