*g* again more on that soon...
and the work I'm doing is an optional add-on to ParaGUI... it just
requires a complete rewrite of the rendering system.  Mostly done really,
just cleaning up the last few boggles...  (note: it works, it just
sometimes crashes on exit).
As soon as I do the next CVS update - most likely tomorrow - to the opengl
branch.

And to reiterate:
        (all going well) the OpenGL branch of CVS to be updated Tues
        OpenGL not required.  Or expected.  (it checks)
        Works as per standard ParaGUI - except with rewritten modular
                graphics rendering.

That's more or less how it works now....
Actually IMHO it's a mistake to have written a custom renderer for it (as
current ParaGUI has) although it's an interesting approach it negates any
bonuses of a platform that has accelerated blitting....
I'm still thinking on this...

G'day, eh? :)
