TrueExponentialBlur & Light Theory

TrueExponentialBlur is a gizmo that hopefully simplifies the task of exponential blurs/glows to a single, physically accurate, operation.

Along with providing a mathematically accurate light falloff, it also managed to achieve the result in a single operation, which blur-stacking methods do not.
