[inline, static]

i + 1 and i - 1 modulo 3

Defined as macros in Trimesh.

define NEXT(i) ((i)<2 ? (i)+1 : (i)-2) define PREV(i) ((i)>0 ? (i)-1 : (i)+2)

According to Trimesh doc,

``This way of computing it tends to be faster than using ''

but I (Roland) just can't believe it... We should profile some code first.
