I was trying out the isosurface in the SuperPatch, when I added a torus to a
long series of formulas. What happened, to my surprise was something I never
expected. I got this error message:

error: Too long function - parser is bored

There must be some of Ken's AI resident within it... I knew it!

So people, can this be solved, or will I just have to live with shorter
functions? BTW, here's the one I used:

{(x^4 + z^4 + y^4 + 2*x^2*z^2 + 2*x^2*y^2 + 2*z^2*y^2 - 2*(r0^2+r1^2)*x^2 +
2*(r0^2-r1^2)*z^2 - 2*(r0^2+r1^2)*y^2 + (r0^2-r1^2)^2)
*
(sqrt(x^2+z^2)-.6)
*
(sqrt(y^2+z^2)-.6)
*
((x-x1)*(x-x2) & (z-z1)*(z-z2) & (y-y1)*(y-y2) + (sqrt(x^2+(y-3)^2+z^2)-1))
*
((x-i1)*(x-i2) & (z-k1)*(z-k2) & (y-j1)*(y-j2) + (sqrt((x-3)^2+y^2+z^2)-1))
*
((x-l1)*(x-l2) & (z-n1)*(z-n2) & (y-m1)*(y-m2) + (sqrt((x+3)^2+y^2+z^2)-1))
*
((x-u1)*(x-u2) & (z-w1)*(z-w2) & (y-v1)*(y-v2) + (sqrt(x^2+(y+3)^2+z^2)-1))}
