Please enable libswscale in ffmpeg build

[GoogleCodeExporter]

I'd like to use libswscale but current ffmpeg build does not enable it.

This is not a 'defect' - it is rather a request for adding "--enable-swscale" 
to the ffmpeg's configure.

Of course, it did it in my tree already. but it would be nice if it worked 
out-of-the-box.
