[IPP] Initial draft of Safe G-Code white paper

[Michael Sweet]

All,

I have posted an initial draft of "A Safe G-Code Subset for 3D Printing" to:

	https://ftp.pwg.org/pub/pwg/ipp/wd/wd-sweet-safe-gcode-20180412.docx
	https://ftp.pwg.org/pub/pwg/ipp/wd/wd-sweet-safe-gcode-20180412.pdf

The purpose of this white paper is to a) define a "safe" subset of G-code we could use as an intermediate pre-sliced format for FDM printers and b) determine what (if any) additional IPP attributes or values are needed to allow a Client or cloud service to generate suitable G-code for printing.

The end goal is to allow entry-level 3D printers with basic networking support to support IPP 3D...
