I did notice that in the MPlayer docs.  I wanted to start with the
simpler one to get a feel of how to turn an mp filter into a regular one.

I also noticed that eq2 has a "simple" mode that is the same as eq.  I
was planning on merging the two into one file, perhaps with a second
filter class that is only allows setting the values from eq.

As an after thought, this could also serve as some slight documentation
for a newbie looking to write their own filter.
