adc_bailout is used to limit how deep the trace_level can go. If the 
contribution of a surface drop under that value, you assume that the actual 
result is "close enough" and stop checking any further.
Increasing it does reduce the quality of the render, but that reduction is often 
not noticeable in *most* cases if you don't increase it to much. adc_bailout 0.1 
is to big, adc_bailout 0.01 to 0.02 is usualy acceptable.
