Looking for a diagram I saw once that explianed "Graphics In Linux"

[RoboJ1M]

Hi,

I once saw a very useful diagram that showed the relationship between all of the disparate segments of the entire graphical sub system of GNU/Linux systems.

It was all baloons connected by lines. But I lost the link and now I can't find it and, as such, can never remember what Mesa does and how it relates to Gallium3D, etc, etc, etc.

Anybody know of this diagram?

Thanks,

J1M.
