    app: add src-format and dest-format properties to gimp:profile-transform
    
    Need to provide the pixels in a format that matches the profile,
    simply using "RGBA float" here was a brain bug of mine. Two profiles
    and two formats are parameters the used GimpProfileTransform needs to
    work correctly.
