[FFmpeg-cvslog] swscale: do not forget to swap data in formats with different endianness

[Kostya Shishkov]

ffmpeg | branch: master | Kostya Shishkov <kostya.shishkov at gmail.com> | Wed Oct 31 11:26:32 2012 +0100| [38fdf7258035eb520ca152e9bea6d95cdfaca424] | committer: Diego Biurrun

swscale: do not forget to swap data in formats with different endianness

Otherwise during scaling it will try to interpret input in the wrong way and
that leads to the test results disagreeing on different platforms and with
different optimizations.
