There have certainly been quite a few features added (especially file
loaders) - but I guess 95% of it was there and working in 1.1.xx.  I
used that version to develop TuxKart.

You can probably just comment out that call.

No the GLS prefix means something else - it's in gls.h - it's somewhat unrelated.

Good plan.

So splash out on an SGI PC - purple! (Lots of $$$ - Linux pre-installed!)

Go look in your local PC store - there are a gazillion $60 PC cases in our
local Fry's in a variety of cool colours and shapes.

Aside from it's shape/colour - I can't think of a single reason to stick with
an Indy (and I used to use one all the time at work).

GLS is a 'stream I/O' protocol for OpenGL - it allows you to pass OpenGL
calls down a comms link or save them into a file...stuff like that.

However, it doesn't do you much good to be able to shunt them around if
you can't render them when they get there!
