[OpenJDK 2D-Dev] Reporitory, Accalerating blits with EA

Hi again,

- The Xrender-pipeline now is almost able to run common swing
applications, copyArea and some bugs are still waiting to be killed,
but more or less it should work after.
Its only the "hack" release where I tried all the stuff out and I plan
to rewrite it starting next week or so, but it would be great if I
could upload it to the OpenJDK repository.
What should I do to get access to it?

- My blit-functions currently are not called if composition with
extra-alpha is requested, although I have registered my Blits with
CompositeType.AnyAlpha. Are there further requirements to get this

- How does ExtraAlpha influence composition for operators other than SRC_OVER?
For now I implement extra-alpha as a 1x1 A8 mask, however although the
results are consistent when SRC_OVER is used, when SRC is used the
image gets darker and darker the lower the EA value becomes with
Xrender, but the RI seems to ignore the the extra-alpha value set.

Thank you in advance, lg Clemens
