[code-reflection] Integrated: added Emanuel Peter's normal mapping demo - not hatified yet

[Gary Frost]

This is a copy of Emanuel Peters 2005 JVMLS Normal Mapping example. 

I made a few changes to accommodate our build structure.  It has been added to hat.java and to maven. 

We should be able tio create a HAT variant of this code. Both to demo GPU perf als this will be a good reference if/when we get around to a VectorAPI backend. 


java -cp hat/job.jar  hat.java bld 
java -cp hat/job.jar hat.java run ffi-opencl normmap
