Description
In 1.7 we created the RenderingEngine pluggable API for antialiased rendering
and line widening to provide for an open source plug to replace our dependency
on the Ductus library.  An example plug was created in the demos directory,
but that plug was only a partial implementation.

An implementation based on open source compatible code needs to be created that
implements the full pluggable API to provide a launching point for the Open JDK
efforts to replace the Ductus library.
Comments
EVALUATION The Pisces library that was created for the Mobile market was used to implement the RenderingEngine and AATileGenerator interfaces and is performing reasonably well. Some remaining issues with the new open source plug: - Performance is not as good as the Ductus library - Fixed point is used with little or no overflow protection - No support for the STROKE_CONTROL hint
