[Radiance-general] -u+ the default option in rtrace with the current release?

[Gregory J. Ward]

Hi Jelle,

Run rtrace -defaults or rpict -defaults to find out.  You'll see that  
it's now the default for rtrace, but rpict still defaults to -u-.   
Nevertheless, there are no true guarantees that two subsequent runs  
will have completely identical results if there are subtle  
differences in the input, which \ cause different sampling patterns  
due to certain thresholds being met or not during rendering.
