Ok, let's the Unsafe variant.

I have created the openjdk branch on my github to track changes:

I pulled it and used get_source.sh to retrieve the complete jdk9 code.

I am going to prepare the initial webrev based on marlin 0.5.5 with the
following changes:
- refactor package org.marlin to sun.java2d.marlin
- refactor class PiscesRenderingEngine to MarlinRenderingEngine

Can I keep the new awt.geom.FastPath2D (or wait for another Path2D patch)
and AAShapePipe patches ?
