glyf (i.e. contour) analysis reports on libre fonts.

I’m not talking about the glyf test code. The wording of the warning message W1110 is exactly the same in the help file from 2003 and 2016. So logic dictates that it was written in or before 2003.

They rewrote the glyf test substantially between 2003 and 2009 and did not update the text. That, to me, indicates that they still thought the text were current when they updated the code.
