if the float pixel * 65535.0f > 2147483647.0f
lrintf may overfow and return negative values, depending on implementation.
nan and +/-inf values may also be implementation defined
clamp the values between 0,1 before scaling, so lrintf
always works.
values <=0.0f, -inf, nan = 0.0f
values >=1.0f, +inf = 1.0f
