Here's the same scene rendered with a patched beta.34 (84 seconds; the 
difference might be due to adc_bailout kicking in for the "ultraviolet" 
rays with genuine beta.34).

Note how this patch keeps the lowest- and highest-wavelength samples 
well within the visible realm for low sample counts, without adversely 
affecting high sample counts. However, the hue is still adversely affected.
