[OpenJDK 2D-Dev] AAShapePipe concurrency & memory waste

[Sergey Bylokhov]

Hi, Laurent.
I am not an expert here but just my 50 cents.
This optimization shall take place only if it is really hotspot. But if 
it is a really hotspot - probably it would be better to remove these 
array/object allocation at all and use plane bytes?
I see that some methods which take it as argument doesn't use them. And 
most of the time we pass AATileGenerator and abox[] to the same methods, 
so it could be merged?

Also I suggest to use jmh for java micrbenchmarks.

So your test will be:
