To ease changing all the VOs to the new OSD rendering, fallbacks, conversions, support code etc. was left all over the code. Now that all VOs have been changed, all that code is inactive. Remove it. Strip down spudec.c. We don't need the old grayscale and scaling stuff anymore. (Not removing spudec itself yet - I'm not confident that the libavcodec DVD sub decoder is sufficient, and it would also require some hacks to get DVD palette and resolution information from libdvdread to libavcodec.) The option --spuaa, --spualign, --spugauss were used with the old sub scaling code, and don't do anything anymore.
