Thanks for your detailed analysis, it matches my variant, so I prefer keeping 
FloatMath with fewer methods.
I agree min/max can use jdk math as I manually inlined important calls inside 
very hot loops in Renderer.

Here is my latest version of FloatMath (jdk branch):
https://github.com/bourgesl/marlin-renderer/blob/jdk/src/main/java/sun/java2d/marlin/FloatMath.java

Marlin renderer 0.9.4.5 has few more patches that I have to propose to 
openjdk/jdk as I did for openjfx:
https://github.com/openjdk/jfx/pull/674

Thanks
