Ok, SDL2 has a migration guide and it will not be a five minutes patch
for Povray.

https://wiki.libsdl.org/MigrationGuide?highlight=%28SDL_WM_SetCaption%29

Most calls made in Povray have been updated to new functions, so there
might be a bit of change in logic too, and a need for detecting libsdl2
along with libsdl1.2 (none, either or both might be present)
