In general lower pretrace_end leads to better quality, but very often
1/image_width is more than necessary. It should correspond to
error_bound, there meaning a lower error_bound should have a lower
pretrace_end.
Some suggested values are:
error_bound 3 => pretrace_end 0.08
error_bound 1 => pretrace_end 0.02
error_bound <1 => pretrace_end 0.01
but they only give a rough idea, for low error_bounds you will probably
have to try what leads to the best quality/speed ratio.
