[Anton Khirnov]

ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Sat May  5 10:22:55 2012 +0200| [25b3babe111a37697d98890400f5864f560ae167] | committer: Anton Khirnov

lavfi: always enable the scale filter and depend on sws.

The scale filter is used for internal colorspace conversions, so it must
always be present.
