+/* 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. Since Sept 2014, file attributes can be found here
+ * if the line starts by G04 #@!
+ * 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
