Radiosity with 5 bounces. Very slight time effect here. In that scene, most 
radiosity ray hit the backgrouns after the first bounce. Whenever you reach the 
background, you stop. You may also reach the adc_bailout well before you've done 
all the bounces. You should see little to no difference between 3 and 5 bounces 
in both time and quality.
