- Irix 4.0.x uses X as its native windowing model...and as such,
- the X server knows about all windows.
- However, GL drawing calls dont generally go through the X server,
- but go directly to the hardware. While every program, even
- ones that use only the GL is an X program in the sense that
- they do talk to the X server to some extent.
- Please note that the person who said that the simulator is
- not an X program _is_ a SGI person...:)...he does know what
- he is talking about.
