Every pen, transform and window command here is the command set of the original Graphic Editor, recovered from PM.TOS on a 360 KB single-sided Atari floppy. Grey is not a colour: it is a 50% vertical dither, every other column, exactly as the 1985 editor wrote it. The 122 stock shapes are decoded from SLIB.SHP — 122 records of 578 bytes, each an 88 × 52 bitmap behind a four-byte header. Dots are 120 dpi across and 72 dpi down, so a shape that looks squat on this square grid prints very nearly square; the panel above shows it at true proportions.
