JDK-8220154 Improve java2d rendering performance on macOS by using Metal framework

[Sergey Bylokhov]

Hi, Alexey.

You are welcome!

I know that one of the goal of this work is to improve the performance of 2d pipeline, did you try to drop the usage of the RenderQueue? I guess metal could be used from the different threads.
Also did you try to compare stuff currently implemented in metal to the equivalent stuff in OGL?
