@jsummers This image (& similar grayscale+alpha examples) are decompiled incorrectly, but seem rendered correctly. TweakPNG shows a weird/incorrect PLTE chunk, but the tRNS chunk seems to show alpha values that are what the grayscale levels are. (FWIW, this was generated from a Wikipedia image transformed via Irfanview & then run through FileOptimizer.)
