[glu3-devel] Still in development?

[Cameron Berkenpas]

Hello,

So is it safe to assume that GLU3 is well on its way to becoming a standard? 
All I've seen is a brief blog post about this.

I had a feeling there was a trick to this, but I wanted to see if there was a 
better ("official") way to go about it. Another way to handle it might be to 
give GLUmat4 a member function that returns a GLfloat *, either way works for 
me.

Yes, glLoadMatrix() is from the old fixed pipeline stuff, but it's convenient 
that GLU3 can be used with the older stuff. :)

Thank you for the response!
