Thanks a lot for the suggestions, especially to mention the references
to discussions and other projects - I've completly forgotten to
include references ;)

Well, it also depends wether the code of the new Direct3D/OpenGL
pipelines will be opened early enough. There are some contraints about
which code may be used.
The disadvantage I see with extending the existing pipelines is code
duplication and not so maintenance friendly code, on the other side
already a lot of stuff already works so its some kind of tradeof. I'll
play a bit with it and see what can be done how ;)

Absolutly, thats the main reason why I think XRender as Java2D backend
makes sence (thanks, seems I've not mentioned this enough).
Some of the open-source drivers bundled with Xorg already accalerate
XRender (Intel, ATI/AMD), and because EXA will be the default
accaleration architecture soon, in the mid-term almost all drivers
will have good XRender accaleration.
I'll put some explanations and links to the proposal to make this more clear.
Thanks a lot for your suggestions, lg Clemens
