First draft of the ballot comments on the new amendment

[Hin-Tak Leung]

Hi Greg,

If you can have a look at the Microsoft code and check soon, that would be great. My implementation ( https://github.com/HinTak/Font-Validator/blob/master/DSIGInfo/DSIGInfo.cs ) was checked against at least all the Win 8.1 and win 7 shipped fonts, so I am fairly sure that's how Microsoft signs their own shipping fonts :-). The checksum's are adjusted to those without the DSIG table, but not zero'ed. 

Martin: If you can locate you old work, conceptually, the hash is simply of "a valid font stripped of the DSIG table + two bytes appended".

 I've not had a chance
 to look at the code to verify this one way or another. It
 seems to me it would be wrong to not zero out the
 CheckSumAdjustment in the head table. I will not be able to
 look at this right away, but hope to soon.
