Require that the voxel is a signed type
...
This means that a static_cast<float> is no longer needed to calculate the
gradient. A static_assert provides user feedback.
The next step here would be to use a MarchingCubesController-type solution
to define the density value from a voxel. This way, also the gradient can
be stored.
