@7c6f434c this breaks renpy, as mentioned in the description; I was hoping to fix that before getting this merged

[7c6f434c]

Oops, sorry

[lheckemann]

To be fair, renpy built fine before this change but it doesn't actually run... So I think the most appropriate course of action would be to mark it as broken?

[7c6f434c]

Well, updating it has a chance of being really easy — need to build the dependencies first, though.

[lheckemann]

It's not really easy, it complains about not being able to find SDL2 even though I've added it to the build inputs.

[7c6f434c]

It is not supposed to be built with pygame anyway, they want their own pygames_sdl2 fork.
