    file-bmp: Fix order of data in RGBA_8888 images
    
    See #678250, #678252, etc. for example bug reports.
    
    This fix should be sufficient in fixing BMP output, but it looks
    like some apps like Firefox have broken BMP loaders which do not
    care for the masks. We would have to change the masks for them.
