Replying to [comment:52 vbraun]:

code with if/else and the ensuing pipeline stalls.
Seriously, you're arguing that rendering 3D figures with NaN coordinates
is a good thing? I find it hard to believe that rendering a figure with
2000 faces (half of which aren't drawn due to !NaNs) is faster than first
removing the offending faces and rendering a figure with 1000 faces.
