If things where that easy... The problem is that in Graphics2D you can set the transform and in PDF you can only add the transform to the current one resulting in a new transform. All kind of tricks with push/restore are needed to make it work as in Graphics2D. Dispose in the copied gc does nothing as many apps write to this gcs interleaved with the original gc. If all the apps behaved as well as yours this wouldn't be an issue.
