[Radiance-general] texfunc with -aa 0

[Stephen Wasilewski]

Hi Greg and Jon,
This is an indirectly lit surface (a ceiling).  I am not seeing the same
patterning I get with -aa >0.  In a small test scene, I see the normal
pertubation if I apply a specularity to the material, but not if it is
purely diffuse, images below are with a diffuse material.  In longer runs
that clean up the noise I see the same lack of pattern:

vwrays -ff -vf 1.vf -x 400 -y 400 | rtrace  `vwrays -d -vf 1.vf -x 400 -y
400` -ffc -n 8  -ab 3 -lr -4 -lw 1e-4 -ad 200 -as 0 -aa 0 -av .04 .04 .04
test.oct > nocache.hdr:
