Smart Morph v1.1
by Sp00kyFox, 2014
Determines the brightest (or darkest) pixel X in the orthogonal neighborship of pixel E (including itself).
Output is a linear combination of X and E weighted with their luma difference d (range: [0.0, 1.0]):
w = sstp{sat[(d - CUTLO)/(CUTHI - CUTLO)]^PWR} * (STRMAX - STRMIN) + STRMIN
with
sstp(x) := smoothstep(0, 1, x) = -2x^3 + 3x^2
sat(x) := saturate(x) = max(0, min(1, x))
