Stand-alone test to create an image using off-screen buffer

Overview
A short code to generate a small PNG image using an off-screen buffer created with GLOffscreenAutoDrawable works perfectly on Windows, Linux, Mac OSX 10.6.8. In OSX 10.9.4 (Mevaricks) produces an empty image, not even background color.

Steps to Reproduce
Compile the code attached and run on a Mac with OSX 10.9.4 Mavericks

Actual Results
A file named test.png 100x100 pixel fully transparent, empty.

Expected Results
PNG file contains solid light pink background.

Offscreen drawable AWT/ImageIO results in black image on OSX/[Java7-Java8]

 - Using our PNGJ writer results in proper images (RGB and RGBA) on all platforms
 - Seems to be a bug w/ AWT/ImageIO

See added unit test in named commit.

Hence -> Invalid.
