    Revert "Add missing (out) annotation to gdk_rgba_parse"
    
    This reverts commit 695860958a9a2e7c825bcec4d0d42b427f0fb47e.
    
    The change introduced an introspection ABI break.

    If we want to move the parse() method to be a constructor or a class
    method, we'll need to do more testing or add new API.
