[Ronald S. Bultje]

ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Tue Jun  7 11:06:44 2011 -0400| [e458b536052a35fe3b0f221ca3ccb308faa84f35] | committer: Ronald S. Bultje

swscale: merge macros that are used only once.

This reduces source code size without affecting the binary.
