[Radiance-general] Cumulative calculations of irradiance

[John Mardaljevic]

Hi Ivan,

When combining irradiance pics you may wish to set the pixel jitter to  
zero (i.e. -pj 0), and render at the final resolution. This will  
prevent different surfaces from possibly contributing to the summed  
irradiance for those pixels that delineate the 'line' between one  
surface and another.  The consequence is more prominent jaggies, but I  
prefer that to 'halos'.

-John
