====== Lip file format ======

Lip is a humanly readable text file via bis tool Wave2Lip that analyses a wss or ogg sound file and produces lip sync for the speaking character.
<code cpp>
frame = 0.040	// constant
0.000, 0	// start time to millisecs, range 0..7
0.080, 2
.....
11.080, -1	//e nd 11.080 is also length of sound file
</code>

  * The range appears to be the various "mimics" you can have on character's face
  * The last time parm == length of sound file
