[arch-dev-public] sdl12-compat

Hi all, SDL1 has been deprecated for a while now but we still have some games and programs which depend on it. Fedora started using SDL's compatbility library sdl12-compat which implements sdl1 using sdl2 which means you can run games under wayland, get better controller support and an actual maintainer library. [1] I've packaged sdl12-compat in [community-testing] and it replaces sdl, it was tested with chromium-bsu, caph and dwarffortress which all runs fine under the compatibility layer. Virtualbox and caph were successfully recompiled to test if we can still rebuild SDL1 programs. Please go forth and test :) [1] https://fedoraproject.org/wiki/Changes/SDL12onSDL2 Greetings, Jelle van der Waa
