Bug 1398: Fixing native test allowing its execution using JOGL 2.3.2 and latest tip using XCode 11

Changes to test
- Using own 'NSApplicationMain' entry to avoid the 'missing Info.plist' message!

- Configurable CLASSPATH and LIBPATH at compile time.
  Note that the java.library.path is now hardcoded as well.

- Don't close stderr in test, just fflush

- Don't close the JVM after launch via 'die(env)', let it run.

- Java: Add GLEventListener RedSquareES2 to see something in action @ 30fps

- Java: GLCanvase visible bounds
