It would be better to use a GL_BGRA and GL_UNSIGNED_INT_8_8_8_8_REV pixel format
and type in conjunction with a TYPE_INT_ARGB BufferedImage in the Screenshot
class if OpenGL 1.2 is available. This is a more optimized code path through
most vendors' OpenGL drivers. See the above forum posting.

Look at src/junit/com/jogamp/test/junit/jogl/offscreen/Surface2File.java,

which uses offscreen/pbuffer rendering,
reads pixel to a texture and uses TextureIO to save it to a file.

The user is free to handle it the way she wants.
