Seems like there are a lot more files being added than are documented in this
file. Is this due to the other files not documented in their current location?

[shadi, 2014/06/24 00:57:38]

Correct. I tried to focus on encrypted files which need some documentation
(which I also know what they are used for :).

 [3] KeyIds and Keys are created by left rotating key ID [1] and key [2] using
     std::rotate for every new crypto period. This is only for testing. The
     actual key rotation algorithm is often much more complicated.

   These differ between implementations because color space-converted frames are
   not specified to the last bit and GLES shader/texture filtering
   precision varies.
