Just to place this info somewhere ...
Nicolas Rougier pointed out to me the function gluPickMatrix, which I though
I'd never known.
Reading back in the red book, it does sound familiar. However, the red book
also proposes an approach to do picking via rendering to the backbuffer, which
is what visvis is using now. Although it might be a wee bit slower, it is
easier than the pickmatrix approach and allows more control over what objects
you want to be able to pick. I'll probably stick to using that approach for the
time being; I expect the changes proposed in issue 41 to improve performance a
lot for this case (see also issue 47).
