Description

I just noticed on the dev branch that the local contrast module is now producing strong halos along edges, as if the laplacian pyramid were shifted during the process. We get more lightness on the dark part of the edge.

This is only with OpenCL disabled and in the darkroom preview. Exports don't seem to be affected.
