Filter Step VEX node

Computes the anti-aliased weight of the step function.

See also: Filter Shadow

This operator computes the anti-aliased weight of the step function. The step function returns 0 if the test value is less than the edge value, and 1 if the test value is greater than the edge value. Filterstep, on the other hand, returns a fraction representing the filtered area under the step function.
