[OpenJDK 2D-Dev] RFR: 8038875: Remove use of ServiceLoader in finding class implementing sun.java2d.pipe. RenderingEngine

[Jim Graham]

If they specify something on the command line, and that doesn't exist, 
then we end up with Pisces even if Ductus is available.  Is that 
intentional?

Also, why the switch from "getProperty(, default)" to the basic 
getProperty() and manually applying the default?
