Request: mouse click to 3d position and ray direction

[gilescope]

Would be cool to show how to go from mouse click to 3d point and ray direction so that if people wanted to select something in 3d they could. This would nicely round off the example. (Thank you for writing the tutorial - much appreciated!)

I'm also having a headache about this, and the creation of shadow mapping

These are too examples that I've been meaning to do. Especially shadow mapping. I might tackle them during the holidays.
