Re: [Glsdk-devel] Tutorials

[Andrew G. <and...@gm...>]

I think we could all easily participate in the peer-review process of the
explanations.  Plus, there's lots of tutorials out there explaining VBOs and
shaders anyway.  Makes for a good starting point.

I think it would be beneficial to include GL2.1 variants of the tutorials as
well, assuming they use the 3.0 forward compatible path (using 2.1
extensions).  That allows use to actually use and test these things on older
hardware (when the tutorials don't require DX10 features) and on non-Windows
platforms (while we wait for 3.0 GLX).
