OpenGL GLX extensions

[Suhaib Siddiqi <s_m_siddiqi at yahoo dot com>]

Below is the info for people who were interested in
SGI OpenGL GLX extensions in XFree for Windows/Cygwin.

The X-server (XWIN.EXE) released yesterday is fully
capable of doing 3D rendering using SGI OpenGL GLX
extensions and double-bufferring etc.

If you are oprting OpenGL/X11 applications from a UNIX
box to Windows, use SGI OpenGL 1.2.1 from "contrib"
directory at 

ftp://sources.redhat.com/pub/cygwin/xfre/contrib.

Remote OpenGL applications from a SGI or other UNIX
boxes should display properly on XWIN X-server.

The XWIN server passed all the SGI OPenGL test
examples
from SGI OpenGL SI 1.2.1.

Below is xglinfo for your info:
