Torque does not return negative values

[martinburch]

Way down in the Torque Category documentation, it's noted in -torque-aggregation-function that "Torque does not return negative values"

The behavior appears to be that all negative values are converted to 0.

Why doesn't Torque return negative values? Can this be fixed?

values outside of 0 - 255 are clamped to that range. To use negative values, the input domain has to be mapped to 0-255.
