Add 6, 11, 15 to the list too. I rendered the whole set to some 
different square image sizes.

I also tried the following fix to great success for pattern use:

   // If seeing numerical noise, try a TINY rotation like:
   rotate z*1e-5

Whether the rotation fix will work where the tiling pattern is used as 
part of an isosurface function will depend upon 'stuff'.
