Now there's support on swscale-test to specify input/output formats,
and also to specify a reference file to avoid unnecessary SSDs. This
halved the time it takes to run the full test (when a reference is
given), so it should be fast enough to run regtests.

OTOH with the addition of crc output, the output is 7.something mb and
the bz2'd output is 500 something kb. It would be nice to have the
results for many different optimizations too, so that would be quite a
lot of data. Does anyone have any good idea on where that should be
made available for the tests to run? (FFmpeg svn, some other repo,
fate-suite/, ...?)
