Since we're touching this subject, is it ok for swscale-example to
depend on libavcodec? (I assume not but it's worth asking). The code
could be simplified and the correct amount of memory used if we use
AVFrame and such.

As another option I think we should add another code as
swscale-example, and turn this one into a regression suite (and not
make it depend on lavc). This code does far more than a simple example
would need, and far less in terms of options (no flags are explained,
etc...). I have a simple swscale example that uses AVFrame and outputs
a png (easy to see the result). What do you think?
