It took me a while to realize, that Canvas3D picking does not use PickingLibrary, instead it passes a picking request to lwjgl functions. I couldn't figure out why setPickable(false) was being ignored on my Nodes until I spent some time with the debugger; pickable is used only by PickingLibrary. 

Should Canvas3D use PickingLibrary instead, especially seeing how PickingLibrary is *much* faster? Or at least make a note that those methods are deprecated and slow, that might save someone else this confusion.

Sorry for making lots of work!

OpenGL picking was once a lot slower. I wanted to kick it out of the API but someone complained. Then I discovered, how to dramatically tune it and it had indeed become a lot faster. Actually I thought, it was just as fast as PickingLibrary or at least the difference wasn't that big.

Long story short, I currently don't remember, if GL-picking has some advantages over software picking. So I would not want to remove it until I have checked it. On the other hand GL-picking is contamenating the render code. So I would love to remove it. I will keep that in mind and thanks for the info.
