This is under beta 5 (win95), but another user has reported that it also
generates an error under beta 6.
Isn't int allowed in iso-functions or is this a bug?
#include "functions.inc"
#declare fn_X = function(x,y,z) {int(x) }
isosurface {
function { fn_X(x, y, z) }
contained_by { box { -1, 1 } }
accuracy 0.001
max_gradient 4
pigment{Yellow}
