From 4cda4b70dbcd21cf57e1e253ddba32b88bcaec18 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>

Subject: 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.
