Remarks

Gets or sets a float value that helps prevent light bleeding (having areas that should be in shadow fully illuminated) for variance shadow mapping.

The value is used to map all shadow values from 0 ... ShadowThreshold to 0 and then linearly rescale the values from ShadowThreshold to 1 into 0 to 1.
