Parameters

job	The compute job to change.
kernelRadius	The kernel radius. A radius of 8 means there's 17x17 taps (8x2 + 1). Changing this parameter will trigger a recompile.
gaussianDeviationFactor	The std. deviation of a gaussian filter.
K	A big K (K > 20) means softer, blurrier shadows; but may reveal some artifacts on the edge cases ESM does not deal well, while small K (< 8) may hide those artifacts, but makes the shadows fat (fatter than normal, still blurry) and very dark. Small K combined with large radius (radius > 8) may cause self shadowing artifacts. A K larger than 80 may run into floating point precision issues (which means light bleeding or weird shadows appearing caused by NaNs). Changing this parameter will trigger a recompile.
