This is for doing masking based off the alpha channel of an image. This is a feature we want to support, but we want a more general imperative API that the declarative thing is built on top of. In the meantime, the code is getting in our way and the feature was already broken (likely from before making sky public). We just paint the mask image on top instead of doing the actual masking. This patch just removes the parsing. Followup patches will remove the implementation code. R=esprehn@chromium.org Review URL: https://codereview.chromium.org/892903002
