This overlay support specifically skips the OpenGL rendering chain, and uses GL rendering only for OSD/subtitles. This is for devices which don't have performant GL support. hwdec_rpi.c contains code ported from vo_rpi.c. vo_rpi.c is going to be deprecated. I left in the code for uploading sw surfaces (as it might be slightly more efficient for rendering sw decoded video), although it's dead code for now.
