Seeking to establish the scale between pixels and mm
Measuring the S71PL129NC0 footprint on L8

4 corner balls of this fp:

	(4698,443)	(5250,443)

	(4697,893)	(5249,895)

rounding width to 552 pixels, height to 450 pixels
the actual dimensions are supposed to be 8.80x7.20 mm

estimating somewhere between 62.5 and 62.8 pixels per mm
