Move implementation private files from com.jogamp.<module>.impl. to jogamp.<module> (1/2) - rename task
- com.jogamp.opengl.impl -> jogamp.opengl - com.jogamp.opengl.util.glsl.fixedfunc.impl -> jogamp.opengl.util.glsl.fixedfunc - com.jogamp.nativewindow.impl -> jogamp.nativewindow - com.jogamp.newt.impl -> jogamp.newt This sorts implementation details from the top level, ie skipping the public 'com', allowing a better seperation of public classes and implementation details and also reduces strings. This approach of public/private seperation is also used in the OpenJDK.
