/* Gerber: NOTES about some important commands found in RS274D and RS274X (G codes):
* Gn =
* G01 linear interpolation (right trace)
* G02, G20, G21 Circular interpolation, meaning trig <0 (clockwise)
* G03, G30, G31 Circular interpolation, meaning trigo> 0 (counterclockwise)
* G04 = comment
* G06 parabolic interpolation
* G07 Cubic Interpolation
* G10 linear interpolation (scale x10)
* G11 linear interpolation (0.1x range)
* G12 linear interpolation (0.01x scale)
* G36 Start polygon mode
* G37 Stop polygon mode (and close it)
* G54 Selection Tool
* G60 linear interpolation (scale x100)
* G70 Select Units = Inches
* G71 Select Units = Millimeters
* G74 disable 360 degrees circular interpolation (return to 90 deg mode)
* and perhaps circular interpolation (return to linear interpolation )
* see rs274xrevd_e.pdf pages 47 and 48
* Unfortunately page 47 said G74 disable G02 or G03
* and page 48 said G01 must be used to disable G02 or G03.
* Currently Gerbview disable G02 or G03 after a G74 command (tests using 2 gerber files).
* G75 enable 360 degrees circular interpolation
* G90 mode absolute coordinates
*
* X, Y
* X and Y are followed by + or - and m + n digits (not separated)
* m = integer part
* n = part after the comma
* Classic formats: m = 2, n = 3 (size 2.3)
* m = 3, n = 4 (size 3.4)
* eg
* GxxX00345Y-06123*
*
* Tools and D_CODES
* Tool number (identification of shapes)
* 10 to 999
* D_CODES:
* D01 ... D9 = command codes:
* D01 = activating light (pen down) when placement
* D02 = light extinction (pen up) when placement
* D03 = Flash
* D09 = VAPE Flash (I never see this command in gerber file)
* D51 = G54 preceded by -> Select VAPE
*
* D10 ... D999 = Identification Tool: tool selection
