equals inconsistent with hashCode in AffineTransform

[Kevin Rushforth]

Your pull request is not yet ready for review (RFR), since it is not 
associated with a JBS bug ID, so it is unlikely that reviewers on this 
list are looking at it. You can file a bug against "Client Libraries" / 
"2d" at https://bugreport.java.com/ (or find a sponsor on this list who 
is willing to file it for you), and then change the title of your PR to 
include that bug ID in the title. See 
https://openjdk.org/guide/#life-of-a-pr for how to format your title.

Once your PR is RFR, you can expect that there will be some discussion 
on it, since you propose to change the implementation of equals, rather 
than limiting your change to the implementation of hashCode.
