Derived routines for shape bitmap mask form nsWindow.cpp, at WindowSurfaceX11Image we compose a final RGBA image and then create the shape mask from image alpha channel. Also the implementation is slightly simplified as it's meant as a fallback only. MozReview-Commit-ID: 6VtGcsVKlcv --HG-- extra : rebase_source : e8b96d68082ae687e376bc89c79f88f9c34cdc15
