Hello

I'm not sure if the pull request below has been noticed, since I have 
not seen evaluation. This is about the equals(Object) method being 
inconsistent with hashCode() in the AffineTransform class. This bug 
prevents the use of AffineTransform as keys in HashMap, unless 
AffineTransform construction is well-controlled or some workaround is 
applied before any use as key.

There is 2 different ways to fix this bug. The one proposed in current 
pull request tries to minimize the behavioral change compared to current 
implementation.
