Maybe it is possible to use the higher precision for this as well.
I assume we just have to use it when converting to
java areas in Java2DConverter.

OK, that's what I expected :-)
As I said, the patch was a quick hack, I just wanted to demonstrate that
we only have to change a few lines to store the higher precision,
and it will not cost more memory.

OK, I see. I'll try with the same data to check what can be changed.
