I would like to reopen the following issue:

Not adding a registrationPoint clip on the stage is the same as adding it in (0, 0).
This was never the problem. The problem is that in this case the registrationPoint concept is not neglected, but destroyed. You can perform any test setting the registrationPoint to (0, 0) and then to (1, 1). You should expect to see little difference, but instead the result is useless.
