[osg-users] Convert from screen space to world space and back to screen space.

[Zach Basanese]

Thanks for the response Steal.

So, if I'm reading that post correctly, I can multiply my vector of (x, y, 0) by ModelInverse*ViewInverse*WindowMatrix, apply my 3D rotations, and then multiply the resulting vector by Model*View*Window to get back to screen-space.

I'll give it a try!
