#77 label distance from camera not quite right

[Anonymous]

Hi,
I've observed that the z-ind computation of a label's distance from the camera (and subsequently which label appears in front) isn't quite right.
Please see example code (it's work on an interactive tree builder)

Thanks for the really awesome project. Exactly what I needed,

I don't know what to look for. A much simpler example is needed.
