Dear Java2D members,

Could someone review the following webrev concerning Java2D Pisces to
enhance its performance and reduce its memory footprint (RendererContext
stored in thread local or concurrent queue):

FYI I fixed file headers in this patch and signed my OCA 3 weeks ago.

Remaining work:
- cleanup (comments ...)
- statistics to perform auto-tuning
- cache / memory cleanup (SoftReference ?): use hints or System properties
to adapt it to use cases
- another problem: fix clipping performance in Dasher / Stroker for
segments out of bounds

Could somebody support me ? ie help me working on these tasks or just to
discuss on Pisces algorithm / implementation ?

Best regards,
Laurent Bourgès
