Note that you can also activate anisotropic texture filtering external to
FlightGear with no code changes if you have nvidia hardware. The nvidia
control panel offers a number of global configuration options. Or you can
do it via an environment variable in linux (read the nvidia driver readme)
export __GL_DEFAULT_LOG_ANISO=3
I would also like to suggest that we should think carefully about hard
coding anisotropic texture filtering into the code and configurations. This
could have a negative performance impact on some platforms, and the actual
implementation details could perhaps be different.
I would prefer some sort of global configuration where the individual users
can set anisotropic filtering for all textures at the same time, versus a
hard coded mechanism to set these for individual textures. We may want to
consider a simlar setting for FSAA if OSG exposes a mechanism to set that.

Curt.
