    Description

      The smask feature /S /Alpha is either not implemented or not working at all. I have two files that are wrongly rendered with the current software, and correctly rendered when the feature is disabled (!). As a first step, I am disabling it for now and attach test files. Johns proposed patch has also disabled the feature, so I think we can agree on that.
