Please add support for overlay planes. Overlay plane hardware is often found on
higher end video hardware such as nVidia's Quadro series of video cards.
Their availability can be queried through glXGetVisualConfigs and/or
glXGetFBConfigs request on X11 platforms and through the wglDescribeLayerPlane
API on Windows. I'm not sure about OSX.
Unfortunately this will require the addition of 8 bit rendering in jogl since
overlay planes are almost exclusively 8 bits deep.
