visual support for other graphics devices

The OpenGL product can be used with devices that have no hardware OpenGL support using the Virtual Memory Driver (VMD) in Virtual GLX mode (VGL). In addition, VMD allows you to use many X11 drawables (local or remote) as “virtual devices” for three-dimensional graphics with OpenGL. This includes rendering to X terminals and other non-GLX extended X servers.
