During implementing the fix for RFE #6899434
it was decided to extract the generic transform support for AWT/Swing
from the specific implementation for Swing components - setTransform()/getTransform().

It is quite clear how this should be done on AWT side,
but there are several possible soultions
how we can make the best out of it on the Swing side.

Having the generic transformation support will enable us
to get the early feedback from the community
and discuss the best solution.

There are three options for the next Swing fix:

1) Provide the generic transformation support only
2) Add JLayer.setTransform() as was discussed before
3) Add setTransform() to another Swing component

All of them will be throughly discussed with the team
