reviewer needed: rendering performance backport.

It depends on
http://hg.openjdk.java.net/jdk7/2d-gate/jdk/rev/47cd69eff641
and
http://hg.openjdk.java.net/jdk7/2d-gate/jdk/rev/4d6f9aaa2600

> Could we not backport that first?

We could, but the above also depend on some other changes that would
need backporting. I'm not sure what these are yet. Should I look
into it and backport everything necessary for the direct patch from
openjdk7 to apply*?

Thanks,
Denis.

*Note: this still won't be completely possible, since in openjdk7
I use @Override notations on methods that implement interface methods,
and ecj doesn't like this, which causes problems with our build.
