Bug 106

---- Reported by bjannu 2004-08-30 13:46:24 ----

JOGL doesn work on Intel extreme graphics (its shared memory graphics hardware).

any JOGL apps fails to start up. 
following is the exception.

This has been fixed by providing a fall-through path in
WindowsGLContext.choosePixelFormatAndCreateContext(); if
wglGetPixelFormatAttribivARB fails with an error code of 0, it falls back to
using ChoosePixelFormat.

This allows at least simple JOGL programs to work on Intel Extreme graphics
hardware. Note that issues have still been seen where if any OpenGL rendering is
done from the AWT thread, attempting to swap the buffers on another thread will
fail. This is a bug in Intel's drivers that can be worked around with careful
organization of the application's JOGL initialization code.
