If mplayer already has libpng for other reasons, then you just have to compare
the difference between the code to use it, vs the code for a pgm decoder and
loader. It's not clear to me that using libpng would be more complex than
writing a loader for pgm images. I suppose I can always write the code and

Just make the entire filter depend on configure finding libpng, which it
already looks for. Once you support png, there really isn't any point to
supporting another format. The advantage of png is that you can use a
compressed bitmap instead of an uncompressed greyscale image, and you could
use png images as well for the alpha-blending filter. In fact, you could use
the SAME png images for both filters.
