Ah yeah fair point. Sorry shoulda thought of that.

It's the release available on the main site, so version 3.6.2, June 2009.
The file I'm currently looking in is render.cpp in the Start_Adaptive_Tracing
method.
I'm getting confused at line 1535, which should be :

for (xx = 0; xx < sub_pixel_size * Frame.Screen_Width + 1; xx++)

Thanks
