Defines at what radius the Gaussian blur optimization kicks in (estimated 25% - 40% faster). The optimization uses slightly less memory and has a quality loss on smallblur radius. 0: use the optimization always (fastest, lowest quality) 3: use the optimization starting at a 3 pixel radius (quite fast) 7: use the optimization starting at a 7 pixel radius (default) >15: barely ever use the optimization (high quality)
Usage
