Ok, I see. The difference comes from different design. Thank you for explanation.
+1 to file as a non-bug difference. On 12/7/06, Alexey Petrenko <[EMAIL PROTECTED]> wrote:

It looks like RI has to transforms in their Graphics2D implementation: from 0,0 to client area and user transform. User can not override first transfrom in this case. Our implementation has just one transform. This makes implementation more clean and easy and let to avoid unnecessary transform composition.
