All depends what you mean by OO, Jacko, all depends...
It's just a tool, a means to and end, not an end in itself, and when it gets in the way - it's the wrong tool! (See recent mention of object-orientated wank
in my diary...) Otherwise I'd be using Smalltalk, and get 2fps.
But I'm always happy to hear some good old concrete suggestions about how to make things better!
BTW, LWJGL is now very much owned by Brian Matzon, Elias Naur, Gregory Pierce, Tristan Campbell, and Luke Holden too now! So bug them, too.
(edit) And Niels Jorgensen too!
