Package: sponsorship-requests Followup-For: Bug #1025642 You're welcome (although I'll mention: I'm not eligible to be a sponsor here, and am only commenting as a peer reviewer).
I'm not sure about that copyright file, because it's stating that the license for the entire src/gui/default_theme.c file is CC-0 - is that what you intend? (my assumption was that your code in that file is intended to be BSD-2-clause, but since there are encoded representations of other files included within it, we should explain what the copyright terms that apply to those files are)
